I kind of reproduce this problem with ffmpeg-svn and
the video streamed here: http://www.youtube.com/watch?v=8z4WvVs7YTc

Would be worth downloading the flv and analyze it using an off-line
NetStream based player.

With GNASH_DEBUG_DECODING uncommented the code does not compile..

NetStream_as.cpp: In member function `void
gnash::NetStream_as::pushDecodedAudioFrames(unsigned int)':
NetStream_as.cpp:1117: error: `_audioQueue' undeclared (first use this function)

Try uncommenting
//#define GNASH_DEBUG_DECODING
in libcore/asobj/NetStream_as.cpp

re-run and attach the log.

Gnash + FFmpeg is still completely unusable with any media. Gnash still doesn't buffer the data properly so any media chops all the time since it'll play the content it has downloaded, run out of frames to play and then download some more as opposed to buffering additional content before running out.

When this happens the debug log shows message like the following..
