[Ffmpeg-devel] Incorrect JPEG decoding

[Cyril Russo]

Hi all,

   I have a JPEG file extacted from a MJPEG stream which decodes
correctly with libjpeg but it is all grey (128 for Y, U and V) when 
decoded with mjpeg.c from libavcodec.
The file can be downloaded from http://xryl669ny.free.fr/MyFile000.jpg


How do you debug the avcodec library ?
Can I be of any help ?

BTW, I'm using the same code with other MJPEG sources, and they work
correctly (422P, J420P and 420P all work okay).

Thanks for helping me solve this bug
