YouTube import fail for some videos (vp9?)

[fenarinarsa]

Describe the current behavior

Youtube import fails for some videos. It looks like yt-dlp is downloading the webm/vp9 version of the video.

Steps to reproduce

1. Try to import the following video https://www.youtube.com/watch?v=FZ5BKKAkGsU
2. Check import logs

Describe the expected behavior

yt-dlp should download the mp4 video instead of the webm version.

It looks like the filter in yt-dlp should better be something like this to avoid vp9/vp9.2/opus codecs:

-f bestvideo*[vcodec!=av01][vcodec!=vp9.2][vcodec!=vp9]+bestaudio[acodec!=opus]/best[vcodec!=av01][vcodec!=vp9][vcodec!=vp9.2][acodec!=opus]/bestvideo[ext=mp4]+bestaudio[ext=m4a]/best

Hi,

Unfortunately 4k videos on youtube use vp9 and are not available in avc1. Then we can't exclude vp9 from the query.

I suggest to upgrade ffmpeg to 5.1, it should fix this issue

[fenarinarsa]

ffmpeg 5.1 is not available for debian bullseye, even in backports, so for now I'll stick with my patch.

You can get ffmpeg static builds from here - https://johnvansickle.com/ffmpeg/

Could the the docker image be updated with such a ffmpeg version to take that into account. I'm encountering the problem for approx 2% of my videos.
