Description John Foliot 2011-07-28 21:49:03 UTC
current text:

"When a video element whose media resource has a video channel is potentially playing, it represents the frame of video at the continuously increasing "current" position. When the current playback position changes such that the last frame rendered is no longer the frame corresponding to the current playback position in the video, the new frame must be rendered. Similarly, any audio associated with the media resource must, if played, be played synchronized with the current playback position, at the element's effective media volume."

recommended change:

"When a video element whose media resource has a video channel is potentially playing, it represents the frame of video at the continuously increasing "current" position. When the current playback position changes such that the last frame rendered is no longer the frame corresponding to the current playback position in the video, the new frame must be rendered. Similarly, any audio, text or other tracks associated with the media resource must, if played, be played synchronized with the current playback position, at the element's effective media volume."

Please state potential issues when filing bugs instead of text substitutions that may or may not make sense.

Deducting from the above the problem seems to be that associated tracks are not synchronized.
