[FFmpeg-user] Error message when combining -vf and -af in command line

[Christian Ebert]

Hi,

Using -vf and -af in 1 command results in this error message:

Only '-vf scale' read, ignoring remaining -vf options: Use ',' to separate filters
Only '-af aresample' read, ignoring remaining -af options: Use ',' to separate filters

The message does not have any consequences.

Happens also with -filter:v plus -filter:a

Does not happen with -filter_complex

Does this mean that -vf plus -af is deprecated? Or is it a bug?

ffmpeg -i BigBuckBunny_640x360.m4v -vf scale -af aresample out.mpeg
