[FFmpeg-user] Transcoding (dvvideo -> libx264) --> not video, only gray

Fri Apr 13 08:44:18 CEST 2012

Hi,

I have installed gpac --> libx264 --> ffmpeg

I have tested x264 and works for me.
I have tested ffmpeg: dvvideo to mpg1 and works.
I have tested ffmpeg: mpg1 to libx264 and works.
But all tests from dvvideo to libx264 makes all frames in gray (all pixels
are gray in each frame)
