[FFmpeg-devel] Irregular codec

Hello All,

I've been writing a demuxer and a decoder for the SMV format (SigmaTel 
Motion Video) for ffmpeg. It begins with a WAV file, then the SMV header 
afterwards, then an array of jpegs. I was trying to get my demuxer to be 
able to read the SMV header, but since it's practically in the middle of 
the file, the buffer is not that big! So I can't read the header through 
the buffer. How can I somehow read in the middle of the file with the 
demuxer_probe(AVProbeData *p) function to be able to read the header 
(especially with demuxer_read_header())?
