We're in control of said dependency and fbarchard is planning on updating the library in time for Mstone-6.

We've fixed a bunch of the audio playback issues (so it shouldn't play twice/in bursts), but we're missing the very beginning part of the sound clip due to a bug in FFmpeg. I've attached the before/after ffmpeg_unittest results based on when FFmpeg was at DEPS r49485 versus tip of tree (currently DEPS r54360)... so we introduced some sort of regression but I think it's the same root issue as issue 49709 . Punting out of Mstone-6 as a result.

Adding two test cases to ffmpeg_unittest from user bug reports.
Issue 47761 (short Ogg files don't play) is currently failing and requires fixing FFmpeg.
Issue 50045 (MP4 moof atom playback issue) is currently passing as expected.

I'm seeing similar behavior with short MP3 files (used for sound effects). Sound will not play twice, or will play only after a long delay. Sometimes the sound is clipped. Very erratic.

Short WAV and MP3 files play properly now with http://codereview.chromium.org/6776024. OGG files if using the default HTML5 UI controls don't want to play the very first 20ms or so of the file though, which is probably a different issue since before this fix, the file wasn't playing at all.
