Comment 1 Gianluca Gabrielli 2021-06-04 12:43:08 UTC

The following packages don't implement the affected function `static av_cold void uninit(AVFilterContext *ctx)`:
 - SUSE:SLE-15-SP2:Update/ffmpeg   3.4.2
 - SUSE:SLE-15:Update/ffmpeg       3.4.2

The following package is already patched:
 - openSUSE:Factory/ffmpeg-4       4.4
