Description
Running e.g. the following command:
ffmpeg -i input.mp4 -vf select='gt(ih\,1080)',scale=-2:1080 output.mp4
causes the following error:
[Parsed_select_0 @ 00000196cee7f500] [Eval @ 00000087f25fe3d0] Undefined constant or missing '(' in 'ih,1080)' [Parsed_select_0 @ 00000196cee7f500] Error while parsing expression 'gt(ih,1080)' [AVFilterGraph @ 00000196cee7f440] Error initializing filters Invalid argument
Support for ih
and iw
constants in the select
filter would allow interesting complex one-line filters.
