By default, yt-dlp tries to download the best available quality if you don't pass any options. This is generally
equivalent to using -f bestvideo*+bestaudio/best. However, if multiple audiostreams is enabled (--audio-multistreams),
the default format changes to -f bestvideo+bestaudio/best. Similarly, if ffmpeg is unavailable, or if you use yt-dlp
to stream to stdout (-o -), the default becomes -f best/bestvideo+bestaudio.
So I think that it should normally pull down the best audio unless you get into some situation where YouTube doesn’t offer a format that simultaneously has the combination of highest audio quality with the highest video quality; if it has to do so to get the highest video quality then, it’ll sacrifice audio quality.
EDIT: Hmm. I could have sworn that there was more text about prioritizing relative audio and video quality at one point in the man page, but I don’t see anything there now. Maybe it can just always get the best audio quality, regardless of video quality, can pull 'em entirely separately.
I mean, you don’t need anything; it’ll work with no flags. I have these:
That’ll just embed some useful metadata in the file.
Note that subtitles doesn’t include automatic subtitles. For that you have to do --write-auto-subs in conjunction
Thanks.
EDIT: There isn’t an
--embed-auto-subs
, but there is a--write-auto-subs
.Fixed thanks.
Also if you just want the audio to listen to (I like to do this with TTRPGs) you can do:
yt-dlp -x -f bestaudio
Also works great in a pinch for getting sounds and music for FoundryVTT.
I’m pretty sure that it defaults to best quality.
goes looking at man page
