Summary of the bug:
Bug has been obviously introduced by commit
e42028925bddfdfe46dcd2b7312148379ef4d62e
(previous commit, 394130efe32f85c1f0582094add4376e32ebf20c, is doing just
fine)
Which is not surprising, since this commit is exactly about first_pts.
while encoding, ffmpeg is complaining about pts/dts. And audio file
contains blank. After a while, it's apparently working normaly again ; but
video and audio are totaly unsynchronized.
How to reproduce:
{{{
% ffmpeg -i bugreport.ts -vsync 1 out.yuv -async 480 -f s16le out.raw
ffmpeg version : git commit e42028925bddfdfe46dcd2b7312148379ef4d62e (and
all git versions since that, including the last one)
built on arch linux, 64bits
}}}
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
