after taking care of mplayer in F-17+ I have tried to check which is the
latest mplayer compiling w/ ffmpeg in F-16. The answer is 2011-09-24
snapshot, aka r34129 - in r34130 CODEC_ID_G729 was added, which is
missing from ffmpeg-0.8 branch.
This is almost a month fresher than what we have now, and limited
testing shows it fixes  at least.
The question is why Rathann chose to update to 2011-08-16 (r34996)
snapshot on 23rd September. Rathann, do you happen to remember? Were
there any things blocking update to later snapshot?
If not, I would like to update mplayer in F-16 to the latest possible
