Fedora 21's gnash-plugin 0.8.10 plays this video in sync with its audio. This can be closed now.

I cannot reproduce with gnash 0.8.11dev (master-21895-8c6e91d) and FFmpeg (avcodec version: 53.35.0)

Yes, seek to 0:01 mostly fixes the sync though it still seems a little off.

I confirm the hiccup and lost sync, but seek-to-start fixes it for me, not there ?

When I browse to this YouTube video:

http://www.youtube.com/watch?v=hMtZfW2z9dw

the audio and video start in sync, then there's a hiccup, then the audio lags behind the video for the rest of the video. Pause/unpause doesn't fix it, rewind-to-the-beginning doesn't fix it.

I'm working from a recent git clone, dc48e20782711e3977ed43367d8ebcd3599c06f5.

I can collect more data on this if necessary. It seems like it should be easily reproducible.
