New submission from Dennis Meuwissen <[EMAIL PROTECTED]>:
When using a cmdline as such:
ffmpeg -i ..\samples\mov.mov -s 720x360 -padtop 60 -r 29.97 -vcodec mpeg2video
-bufsize 1835008 -packetsize 2048 -muxrate 10080000 -minrate 8000k -maxrate
8000k -b 8000k -sws_flags +bilinear -an -threads 2 -strict 2 -f mpeg2video -map
0:0 output.mpg
Resulting mpeg plays but is entirely green. This does not happen when -sws_flags
+lanczos or spline is used, but does when bilinear and fast_bilinear is used. I
have not tried other sws filters.
FFMPEG output looks normal:
