+SIL OPEN FONT LICENSE
+Version 1.1 - 26 February 2007
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS

+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as

+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font

+   * Primary timing in VHS goes by video. This is different from most media players, as
+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^

+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may
+   * not be aligned perfectly, even for matching segment indexes.

+   *    00100000 = length 3 because there are 2 zeros before a 1.
+   *    00000011 = length 7 because there are 6 zeros before a 1.
+   *
+   * 2. The bits used for length are removed from the first byte
+   *    Then all the bytes are merged into a value. NOTE: this
+   *    is not the case for id ebml tags as there id includes

+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader            ^
+   *
+   * In the above example, both audio and video loaders are loading segments from timeline
+   * 0, but imagine that the seek originated from timeline 1.
+   *
+   * When seeking to a new timeline, the timestamp offset will be set based on the expected
+   * segment start of the loaded video segment. In order to maintain sync, the audio loader
+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may

+لا، لا شيئ البتة

+00:06:40.625 --> 00:06:42.958

+وكيف... وكيف أنه غاية في الكمال
+
+58
+00:07:24.083 --> 00:07:27.417
+! لا يا بروغ، لا أرى ذلك
+
+59
+00:07:27.542 --> 00:07:30.333
+لا أرى ذلك لأنه لا يوجد شيئ هناك
+
+60
+00:07:31.500 --> 00:07:35.333

+لشيئ لا وجود له ؟

+Ingenting.
+- Säker?
+
+42
+00:06:06.333 --> 00:06:07.958
+Ingenting alls.
+
+43
+00:06:08.042 --> 00:06:12.625
+Jaså. och till höger om dig...
+Vad ser du där. Emo?
+
+44
+00:06:13.750 --> 00:06:15.583
+Samma där Proog...
+
+45
+00:06:15.583 --> 00:06:18.083
+Exakt samma där. ingenting!
+
+46
+00:06:18.083 --> 00:06:19.667
+Perfekt.
+
+47
+00:06:40.500 --> 00:06:42.917
+Lyssna Proog! Hör du?
+
+48
+00:06:43.500 --> 00:06:45.125
+Kan vi gå dit?
+
+49
+00:06:45.208 --> 00:06:48.125
+Gå dit?
+Det är inte tryggt.
+
+50
+00:06:49.583 --> 00:06:52.583
+Men. men...
+- Tro mig. det inte säkert.
+
+51
+00:06:53.000 --> 00:06:54.292
+Men kanske om jag -
+
+52
+00:06:54.292 --> 00:06:56.333
+Nej.
+
+53
+00:06:57.208 --> 00:07:00.167
+Men -
+- Nej. NEJ!
+
+54
+00:07:00.917 --> 00:07:03.792
+Några fler frågor Emo?
+
+55
+00:07:04.250 --> 00:07:05.875
+Nej.
+
+56
+00:07:09.542 --> 00:07:11.375
+Emo?
+- Ja?
+
+57
+00:07:11.542 --> 00:07:15.667
+Emo. varför...
+
+58
+00:07:15.792 --> 00:07:18.583
+Varför kan du inte se skönheten i det här?
+
+59
+00:07:18.792 --> 00:07:21.708
+Hur det fungerar.
+
+60
+00:07:21.833 --> 00:07:24.000
+Hur perfekt det är.
+
+61
+00:07:24.083 --> 00:07:27.333
+Nej Proog. jag kan inte se det.
+
+62
+00:07:27.333 --> 00:07:30.333
+Jag ser det inte. för det finns inget där.
+
+63
+00:07:31.292 --> 00:07:35.333
+Och varför skulle jag lägga mitt liv
+i händerna på något som inte finns?
+
+64
+00:07:35.333 --> 00:07:37.083
+Kan du berätta det för mig?
+- Emo...
+
+65
+00:07:37.083 --> 00:07:39.167
+Svara mig!
+
+66
+00:07:43.500 --> 00:07:45.208
+Proog...
+
+67
+00:07:45.208 --> 00:07:47.083
+Du är inte frisk!
+
+68
+00:07:47.167 --> 00:07:49.292
+Håll dig borta från mig!
+
+69
+00:07:52.292 --> 00:07:55.083
+Nej! Emo!
+Det är en fälla!
+
+70
+00:07:55.375 --> 00:07:57.208
+Heh. det är en fälla.
+
+71
+00:07:57.208 --> 00:08:01.708
+På vänster sida ser vi...
+Babylons hängande trädgårdar!
+
+72
+00:08:01.958 --> 00:08:04.000
+Vad sägs om den fällan?
+
+73
+00:08:05.458 --> 00:08:07.333
+Nej. Emo.
+
+74
+00:08:08.917 --> 00:08:12.667
+Till höger ser vi...
+Gissa!
+
+75
+00:08:12.750 --> 00:08:15.125
+Rhodos koloss!
+
+76
+00:08:15.375 --> 00:08:16.500
+Nej!
+
+77
+00:08:16.500 --> 00:08:20.250
+Kolossen på Rhodos!
+Och den är här för din skull. Proog...
+
+78
+00:08:20.250 --> 00:08:23.250
+Bara för din skull.
+
+79
+00:08:50.917 --> 00:08:53.250
+Den är där...
+
+80
+00:08:53.625 --> 00:08:56.417
+Tro mig.
+Emo...
+
+81
+00:08:57.000 --> 00:09:00.000
+Det är den.
+Det är den...

+00:00:00.000 --> 00:00:05.000

+The orange open movie project presents

+

+2

+00:00:05.010 --> 00:00:12.000

+Introductory titles are showing on the background of a water pool with fishes swimming and mechanical objects lying on a stone floor.

+

+3

+00:00:12.010 --> 00:00:14.800

+elephants dream

+

+4

+00:00:26.100 --> 00:00:28.206

+Two people stand on a small bridge.

+

+5

+00:00:30.010 --> 00:00:40.000

+The old man, Proog, shoves the younger and less experienced Emo on the ground to save him from being mowed down by a barrage of jack plugs that whir back and forth between the two massive switch-board-like walls.

+

+6

+00:00:40.000 --> 00:00:47.000

+The plugs are oblivious of the two, endlessly channeling streams of bizarre sounds and data.

+

+7

+00:00:48.494 --> 00:00:51.994

+Emo sits on the bridge and checks his limbs.

+

+8

+00:01:09.150 --> 00:01:16.030

+After the squealing plugs move on, Proog makes sure that Emo is unharmed and urges him onwards through a crack in one of the plug-walls.

+

+9

+00:01:18.050 --> 00:01:24.000

+They walk through the narrow hall into a massive room that fades away into blackness on all sides.

+

+10

+00:01:24.050 --> 00:01:34.200

+Only one path is visible, suspended in mid-air that runs between thousands of dangling electric cables on which sit crowds of robin-like robotic birds.

+

+11

+00:01:36.000 --> 00:01:40.000

+As Proog and Emo enter the room, the birds begin to wake up and notice them.

+

+12

+00:01:42.000 --> 00:01:50.000

+Realizing the danger, Proog grabs Emo by the arm.

+

+13

+00:01:50.050 --> 00:02:00.000

+They run along the increasingly bizarre path as the birds begin to swarm.

+

+14

+00:02:00.050 --> 00:02:11.000

+All sound is blocked out by the birds which are making the same noises as the jack-plugs, garbled screaming and obscure sentences and static.

+

+15

+00:02:12.600 --> 00:02:17.000

+The path dead-ends, stopping in the middle of no-where above the infinite drop.

+

+16

+00:02:17.600 --> 00:02:22.000

+Proog turns around as the birds reach them and begin to dive-bomb at them.

+

+17

+00:02:22.600 --> 00:02:28.000

+At the last moment, Proog takes out an old candlestick phone and the birds dive into the speaker piece.

+

+18

+00:02:28.600 --> 00:02:31.000

+The screen cuts to black.

+

+19

+00:02:31.600 --> 00:02:38.000

+In the next scene, Proog stands at one end of a room, suspiciously watching what is probably the same candlestick phone, which is ringing.

+

+20

+00:02:38.500 --> 00:02:41.000

+Emo watches from the other side of the room.

+

+21

+00:02:41.500 --> 00:02:43.000

+The phone continues to ring.

+

+22

+00:02:43.500 --> 00:02:48.000

+After a while Emo approaches it to answer it, but Proog slaps his hand away.

+

+23

+00:02:57.972 --> 00:02:59.100

+Proog takes the ear-piece off the hook.

+

+24

+00:03:13.500 --> 00:03:18.054

+The phone speaker revealed a mass of clawed, fleshy polyps which scream and gibber obscenely.

+

+25

+00:03:25.000 --> 00:03:33.000

+There is a solemn silence as Emo looks around the room and the technical objects therein.

+

+26

+00:03:38.000 --> 00:03:44.000

+Emo laughs disbelievingly and Proog walks away.

+

+27

+00:03:46.000 --> 00:03:54.000

+In the next scene, the two enter another massive black room.

+

+28

+00:03:54.500 --> 00:04:04.000

+There is no path, the entry platform is the only structure that seems to be there except for another exit, lit distantly at the far side.

+

+29

+00:04:04.500 --> 00:04:14.000

+Proog takes a step forward into the void, and his feet are suddenly caught by giant typewriter arms that rocket up out of the blackness to catch his feet as he dances across mid-air.

+

+30

+00:04:14.500 --> 00:04:22.000

+Emo follows Proog with somewhat less enthusiasm as the older man leads the way.

+

+31

+00:04:52.000 --> 00:04:58.000

+They reach the end of the room and go through a hall into a small compartment.

+

+32

+00:05:02.000 --> 00:05:06.000

+Proog presses a button, and the door shuts.

+

+33

+00:05:06.500 --> 00:05:09.000

+It is an elevator.

+

+34

+00:05:09.500 --> 00:05:24.000

+The elevator lurches suddenly as it is grabbed by a giant mechanical arm and thrown upwards, rushing up through an ever-widening tunnel.

+

+35

+00:05:26.500 --> 00:05:32.000

+When it begins to slow down, another arm grabs the capsule and throws it even further up.

+

+36

+00:05:32.500 --> 00:05:40.000

+As it moves up, the walls unlock and fall away, leaving only the floor with the two on it, rushing higher and higher.

+

+37

+00:05:54.500 --> 00:05:59.000

+They exit the tunnel into a black sky and the platform reaches the peak of its arc.

+

+38

+00:06:19.500 --> 00:06:26.000

+The elevator begins to drop down another shaft, coming to rest as it slams into the floor of another room and bringing the two to a level stop.

+

+39

+00:06:26.500 --> 00:06:28.000

+A camera briefly illumiates.

+

+40

+00:06:28.010 --> 00:06:34.000

+They are in a large, dingy room filled with strange, generator-like devices and dotted with boxy holographic projectors.

+

+41

+00:06:34.500 --> 00:06:38.000

+One of them is projecting a portion of wall with a door in it right beside them.

+

+42

+00:06:38.500 --> 00:06:40.000

+The door seems harmless enough.

+

+43

+00:06:42.800 --> 00:06:45.100

+From behind the door comes light music.

+

+44

+00:06:56.000 --> 00:07:00.100

+Proog presses a button on his cane, which changes the holograph to another wall.

+

+45

+00:07:05.100 --> 00:07:11.000

+Proog finishes the wall, and boxes them into a Safe Room, out of the view of anything outside.

+

+46

+00:07:39.000 --> 00:07:42.500

+Proog slaps him, trying to bring him to his senses.

+

+47

+00:07:45.000 --> 00:07:52.000

+Emo storms away down the length of the room towards a wall he apparently cannot see and the wall begins to move, extending the length of the room.

+

+48

+00:08:00.000 --> 00:08:07.000

+The walls begin to discolour and mechanical roots start tearing through the walls to his left.

+

+49

+00:08:07.010 --> 00:08:09.000

+The roots move forwards toward Proog.

+

+50

+00:08:22.000 --> 00:08:31.000

+The rest of the safety wall crumples away as a pair of massive hands heave out of the ground and begin to attack.

+

+51

+00:08:31.010 --> 00:08:37.000

+Proog is knocked down by the shockwave, while Emo turns and begins to walk away, waving his finger around his temple in the 'crazy' sign.

+

+52

+00:08:37.010 --> 00:08:44.000

+In a last effort, Proog extricates himself from the tentacle roots, and cracks Emo over the back of the head with his cane.

+

+53

+00:08:44.500 --> 00:08:51.000

+As Emo collapses, everything falls away, and Proog and Emo are left in one tiny patch of light in the middle of blackness.

+

+54

+00:09:00.000 --> 00:09:20.000

+The scene fades to black while panning over a pile of tentacle roots lying on the ground.

+ * Primary timing in VHS goes by video. This is different from most media players, as
+ * audio is more often used as the primary timing source. For the foreseeable future, VHS
+ * will continue to use video as the primary timing source, due to the current logic and
+ * expectations built around it.
+
+ * Since the timing follows video, in order to maintain sync, the video loader is
+ * responsible for setting both audio and video source buffer timestamp offsets.
+ *
+ * Setting different values for audio and video source buffers could lead to
+ * desyncing. The following examples demonstrate some of the situations where this
+ * distinction is important. Note that all of these cases involve demuxed content. When
+ * content is muxed, the audio and video are packaged together, therefore syncing
+ * separate media playlists is not an issue.
+ *
+ * CASE 1: Audio prepares to load a new timeline before video:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:                     ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader              ^
+ *
+ * In the above example, the audio loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the video loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the audio loader goes ahead and loads and appends the 6th segment before the video
+ * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+ * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+ * the audio loader must provide the audioAppendStart value to trim the content in the
+ * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+ * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+ * segment until that value is provided.
+ *
+ * CASE 2: Video prepares to load a new timeline before audio:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:             ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader                      ^
+ *
+ * In the above example, the video loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the audio loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the video loader goes ahead and loads and appends the 6th segment, then once the
+ * segment is loaded and processed, both the video and audio timestamp offsets will be
+ * set, since video is used as the primary timing source. This is to ensure content lines
+ * up appropriately, as any modifications to the video timing are reflected by audio when
+ * the video loader sets the audio and video timestamp offsets to the same value. However,
+ * setting the timestamp offset for audio before audio has had a chance to change
+ * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+ * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+ *
+ * CASE 3: When seeking, audio prepares to load a new timeline before video
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:           ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader            ^
+ *
+ * In the above example, both audio and video loaders are loading segments from timeline
+ * 0, but imagine that the seek originated from timeline 1.
+ *
+ * When seeking to a new timeline, the timestamp offset will be set based on the expected
+ * segment start of the loaded video segment. In order to maintain sync, the audio loader
+ * must wait for the video loader to load its segment and update both the audio and video
+ * timestamp offsets before it may load and append its own segment. This is the case
+ * whether the seek results in a mismatched segment request (e.g., the audio loader
+ * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+ * loaders choose to load the same segment index from each playlist, as the segments may

+   *
+   * User activity gets checked asynchronously. So what could happen is a tap event
+   * on the video turns the controls off. Then the `touchend` event bubbles up to
+   * the player. Which, if it reported user activity, would turn the controls right
+   * back on. We also don't want to completely block touch events from bubbling up.
+   * Furthermore a `touchmove` event and anything other than a tap, should not turn
+   * controls back on.

+ * Primary timing in VHS goes by video. This is different from most media players, as
+ * audio is more often used as the primary timing source. For the foreseeable future, VHS
+ * will continue to use video as the primary timing source, due to the current logic and
+ * expectations built around it.
+
+ * Since the timing follows video, in order to maintain sync, the video loader is
+ * responsible for setting both audio and video source buffer timestamp offsets.
+ *
+ * Setting different values for audio and video source buffers could lead to
+ * desyncing. The following examples demonstrate some of the situations where this
+ * distinction is important. Note that all of these cases involve demuxed content. When
+ * content is muxed, the audio and video are packaged together, therefore syncing
+ * separate media playlists is not an issue.
+ *
+ * CASE 1: Audio prepares to load a new timeline before video:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:                     ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader              ^
+ *
+ * In the above example, the audio loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the video loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the audio loader goes ahead and loads and appends the 6th segment before the video
+ * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+ * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+ * the audio loader must provide the audioAppendStart value to trim the content in the
+ * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+ * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+ * segment until that value is provided.
+ *
+ * CASE 2: Video prepares to load a new timeline before audio:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:             ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader                      ^
+ *
+ * In the above example, the video loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the audio loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the video loader goes ahead and loads and appends the 6th segment, then once the
+ * segment is loaded and processed, both the video and audio timestamp offsets will be
+ * set, since video is used as the primary timing source. This is to ensure content lines
+ * up appropriately, as any modifications to the video timing are reflected by audio when
+ * the video loader sets the audio and video timestamp offsets to the same value. However,
+ * setting the timestamp offset for audio before audio has had a chance to change
+ * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+ * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+ *
+ * CASE 3: When seeking, audio prepares to load a new timeline before video
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:           ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader            ^
+ *
+ * In the above example, both audio and video loaders are loading segments from timeline
+ * 0, but imagine that the seek originated from timeline 1.
+ *
+ * When seeking to a new timeline, the timestamp offset will be set based on the expected
+ * segment start of the loaded video segment. In order to maintain sync, the audio loader
+ * must wait for the video loader to load its segment and update both the audio and video
+ * timestamp offsets before it may load and append its own segment. This is the case
+ * whether the seek results in a mismatched segment request (e.g., the audio loader
+ * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+ * loaders choose to load the same segment index from each playlist, as the segments may

+   * EBLM uses "vints" tags. Every vint tag contains

+   * 1. The length from the first byte. You get this by
+   *    converting the byte to binary and counting the zeros
+   *    before a 1. Then you add 1 to that. Examples
+   *    00011111 = length 4 because there are 3 zeros before a 1.
+   *    00100000 = length 3 because there are 2 zeros before a 1.
+   *    00000011 = length 7 because there are 6 zeros before a 1.
+   *
+   * 2. The bits used for length are removed from the first byte
+   *    Then all the bytes are merged into a value. NOTE: this
+   *    is not the case for id ebml tags as there id includes
+   *    length bits.

+   * Primary timing in VHS goes by video. This is different from most media players, as
+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader            ^
+   *
+   * In the above example, both audio and video loaders are loading segments from timeline
+   * 0, but imagine that the seek originated from timeline 1.
+   *
+   * When seeking to a new timeline, the timestamp offset will be set based on the expected
+   * segment start of the loaded video segment. In order to maintain sync, the audio loader
+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may
+   * not be aligned perfectly, even for matching segment indexes.
