Hi,
While helping a guy to stack 'scale' and 'crop' video filters, we've
encountered a possible bug, so I think it's better to report it, although
I'm not sure if the duplicate of this report exist.
Anyway: "scale=-1:480,crop=iw-mod(iw,2):480" gives: No such filter:
'2):480'
when
-vf "scale=-1:480,crop=iw-mod(iw,2):480"
is given, ffmpeg mistakes the comma in the parenthesis for the delimiter
of video filters (or this is the intended behavior?)
however, the issue can be resolved with a workaround:
"scale=-1:480,crop=(iw-mod(iw\,2)):480"
