1909	Add support for skipping a header for rawvideo inputs	erezst		"Some programs dump uncompressed video files with a custom header at the beginning. To use these files as inputs for FFMPEG, the rawvideo codec needs to be able to skip this header.

The input format is:
    [ Header - e.g. 100 bytes]
    [ Frame #1 ]
    [ Frame #2 ]
    [ ... ]
    [ Frame #N ]

Header -- a fixed-length header (for example, 100 bytes).
Frame - A raw video frame in some pix_fmt (e.g. YUV422p).

A command-line for encoding this file to H.264 might be:

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 this feature request is about."	enhancement	closed	wish	FFmpeg	git-master	fixed					1	0
