Description

When I try to run script on streaming video it freezes for ten seconds and gives me a prompt with a general error(Encode failed! Check logs). It only occurs when I use it with ani-cli script(https://github.com/pystardust/ani-cli). I have no problem encoding streaming video from youtube (mpv "https://www.youtube.com/videolink") and cutting files on my local HDD. It worked well, until I had to update ani-cli script again(because their sources switching encryption keys frequently). Then it failed to evoke an mpv. So I updated mpv and all dependencies from official rep. Then it started to give that error. I updated your script as well, but nothing change. I don't have a backup, so I can't provide more information about working version I was using(it was at least couple month old).
