[FFmpeg-user] decoding to raw format

[William Pearlman]

I have not ben able to decode h264 video to raw format (sequence of
headerless image frames).  Here is an example of the dialog.

Unrecognized option 'rawvideo'.
Error splitting the argument list: Option not found
--------------------------------------------------------------------------------------------
I have written omitting "-rawvideo" and just the "-" and specified
"-decoder=h264" and get "Unrecognized option" or "Unrecognized format".

The 252037.h264 file was produced by "ffmpeg -i 252037.mov 252037.h264".
  The compression relative to MOV was impressive and the quality displayed
using ffplay was excellent.  Please tell me the correct command line usage.
  Thank you.
