quickfix:

diff -r vlc-2.1.2-orig/modules/codec/avcodec/video.c 
vlc-2.1.2-orig-1/modules/codec/avcodec/video.c
891a892,895
>             if(!p_src){
>                 //msg_Err( p_dec, "ffmpeg_CopyPicture`: 
> p_ff_pic->data[%d]==0, p_pic->i_planes==%d", i_plane, p_pic->i_planes );
>                 continue;
>             }

this doesn't fix the source of the problem but at least vlc doesn't
crash
