[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Thu Apr 20 09:36:03 2023 +0200| [38c937e8c48608fd1574729365aa991b189138cb] | committer: Anton Khirnov

fftools/ffmpeg: drop undocumented runtime debug-setting

This feature is of highly questionable usefulness and - as the comment
in the code says - is not actually supported by the API.
