+   * 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

+   * 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.

+ * Returns whether or not the loader should wait for a timeline change from the timeline
+ * change controller before processing the segment.
+ *
+ * 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.

+ *
+ * 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.

+   * 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.
