[Libav-user] change pixel format without scaling data ? // more3

[jim morgenstern]

Sorry -- top-posting is anew concept for me;  email says plain text.

I use this many ways.  For one instance:  
Input is YUV422
Output Is RGB16

#define YUV444 PIX_FMT_YUV444P16LE

(That must of course make the code much more readable and significantly ease the search for a problem as the one you seem to be having...)

So what did you pass as in_pix_fmt and out_pix_fmt ?

Please do not top-post on this mailing list, it is considered rude. And please force your mailer to "text-only".
