[FFmpeg-devel] Unable to transcode correctly MPEG2 video file to uncompressed MOV file

[Thomas Parmegiani]

Hi all !

I am trying to transcode MPEG2 video file to uncompressed mov file. I did
not get any errors and the file seems to be readable both on OSX and WINXP.
But the resulting file is filled with white blank frames. Is it a problem of
conversion or did I miss a parameter ?

Thanks in advance,

Thomas
