I'll explain in further details. I have a program that dumps video into a custom format.The format is: [ Header - 100 bytes] [ Frame #1 ] [ Frame #2 ] [ ... ] [ Frame #N ]
Header -- a fixed-length header (100 bytes).Frame - A raw video frame in YUYV422.
I am trying to convert the file to an H.264 stream, but or that I need a way to skip the header.
I would like to run a command similar to-
ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt yuv422p -skipheader 100 -i <SOURCE_VIDEO> -s 640x480 -r 30 -vcodec libx264 <OUTPUT_FILE>The '-skipheader 100' parameter is what I can't find.
I prefer to have this capability as part of ffmpeg, and avoid an unnecessary file-copy as uncompressed files are huge.

Sorry about that -- didn't know the proper netiquette.
