Hi , All
Amit Dor-Shifer in "Encoding raw alaw to PCM"
asked if ffmpeg able to decode raw g729 stream into some form of PCM
Quick investigation shows that such decoding is not possible with
existing raw pcm demuxers due to lack
of proper g.729 initialization.
Attached patch adds simple demuxer especially for g.729.
With this patch FFmpeg can decode provided sample using "ffmpeg -f
g729 -i test_123.sample test_123.wav" command line(or even "ffmpeg -i
test123.g729 test123.wav" after renaming sample file).
I've also added special option "bit_rate" for selecting between @8k
and @6.4k modes.
Asking for review/comment.
