When running youtube-dl (without any parameters) it always checks ffmpeg and ffprobe versions twice.

07:10:23.459397       25389 /sbin/ldconfig -p

07:10:23.582957       25393 ffmpeg -version
07:10:23.634771       25394 ffprobe -version
07:10:23.687911       25397 ffmpeg -version
07:10:23.734922       25398 ffprobe -version

I think it's useless to check versions of binaries twice.
I'd be happy with a --force-ffmpeg-version=4.0.2 parameter, for skip checking binaries on every run. (I run a dozens of youtube-dl per one second)

If you run it without any parameters it should not check anything. If you run it with -v it will check each executable once for debug output. It may output it twice due to avconv/avprobe symlinked to ffmpeg counterparts on your OS. Read issue template and provide complete verbose log along with strace output.

Ok, i have a /etc/youtube-dl.conf which contains
--add-metadata --embed-thumbnail
parameters. Each of them checking for ffmpeg once. Can it be one check at all? Or no check at all with a parameter?
