Dear experts,

I need to decode (and export as jpg) H.264 and MPEG-2 I-pictures from within 
the source code of an application I'm writing in C. I linked against libavcodec 
in the hope that avcodec_decode_video() could do it but it seems that it only 
works for .mpg and not for raw elementary streams. I basically used the code 
from libavcodec's old apiexample.c (no AVPacket).

Using ffmpeg on the 2 samples provided, I can easily decode them:
ffmpeg -f h264 -i sample.264 -s 600x400 sample_%d.jpg
ffmpeg -f mpegvideo -i sample.mpeg2 -s 600x400 sample_%d.jpg

Can you please point out the function that I should use to achieve this using 
libavcodec?


Also same question in 
http://ffmpeg.org/pipermail/libav-user/2011-April/000053.html.But links 
missed.Can you help me?
