[FFmpeg-user] Decoding Raw YUV Frames From MPEG2

[Stu]

Hello,

I know this sounds pretty obvious, but I'm having trouble getting accurate results when decoding a standard MPEG2 video file into its component raw YUV.

My command line is simple (from the documentation page):-
ffmpeg -i F:\ak.m2v output.yuv

Looking at the output file in a hex editor, a significant percentage of samples are out of range (16-235).  MPEG2 can't physically store samples like this, so I'm curious as to where they are coming from and if they can be clipped.

This was run with the ffmpeg-20130202-git-985e93a-win64-static build, btw.

Regards
