dirkf commented 1 month ago

Or ask for .mkv and sort out any desired conversion locally. Or pass additional ffmpeg arguments to force transcoding during the merge step (may fall into the category of "possible but inadvisable").

The message vp9 only supported in MP4 from ffmpeg is misleading. MP4 and MOV are technically similar containers, so the same muxer code handles both, but they support different content types. The message lacks the introductory context "Out of the two major container formats that this code implements, ...".

stephane-archer commented 1 month ago

why would it be in the category of "possible but inadvisable"? otherwise my next command would be ffmpeg -i downloadedvideo.mkv output.mov because my next program can't read mkv

bashonly commented 1 month ago

can your next program read mp4?

--merge-output mp4 --remux mp4

should work in most cases

bashonly commented 1 month ago

or if you only want to download codecs that are supported by the mov container:

-S vcodec:h264,res,acodec:aac --merge-output mov --remux mov
stephane-archer commented 1 month ago

@bashonly the next program is final cut: https://support.apple.com/en-gb/guide/final-cut-pro/ver2833f855/mac so it supports the mp4 container but not the vp9 codec, (h265 works) Does this next line make sense to get the best quality with a compatible format? is there a way to sort formats for video and audio separately? -S vcodec:h265,vcodec:h264,quality,res,acodec:aac --merge-output mov --remux mov

bashonly commented 1 month ago

vcodec:h265,vcodec:h264 is not valid syntax

youtube doesn't serve h265 anyways, so I think -S vcodec:h264,res,acodec:aac --merge-output mov --remux mov should be enough

stephane-archer commented 1 month ago

@bashonly what about: yt-dlp -f 'bestvideo*[vcodec*=avc1]+bestaudio[acodec*=mp4a]' --merge-output mov $argv is it better to use -f or -S?

bashonly commented 1 month ago

It's better to use -S. Format sorting is "smart" and knows that h264 == avc == avc1, etc. With -f you need to be exact, and the representation of the codec can vary from site to site.

stephane-archer commented 1 month ago

@bashonly Moving back to the original subject of the opened issue, does yt-dlp --recode mov always transcode, or is able to remux compatible format with the target container?

bashonly commented 1 month ago

--recode will always re-encode. --remux will losslessly remux; but it only works if the codecs are compatible with the target container. Re-encoding can change the codec+container; remuxing can only change the container.

stephane-archer commented 1 month ago

so we can imagine an option like: --smart-recode or the fact of using --recode and --remux at the same time should avoid useless re-encode?
