You always should append .%(ext)s to the output template, otherwise it might cause even more problems (Like when the name contains a .).

Why do you want to download without the extension in the first place?

dirkf commented 2 weeks ago

Presumably the merge process is applying the extension even though it wasn't specified in the output template.

Actually, as the first log shows, yt-dlp is forcing the {format_id}.webm extension to avoid having one format overwrite the other (function correct_ext(), I think), the merge command is using a temp.webm extension for the output, and that is being renamed by just removing the temp. part (because dl_filename passed to the post_process() is that temp filename when no file has been downloaded).

Would the answer to this be a documentation note that an output template with no %(ext)s is likely to cause unexpected behaviour except in very simple cases, like downloading one combined format video with a specific filename?

pukkandan commented 2 weeks ago

I swear there is an open issue for this, but I can't find it

krasnh commented 2 weeks ago

but I can't find it

And I was looking for it. I was also surprised that for the entire existence of "yt-dlp", I was the first one who encountered this problem. :)

upd. If this is not a problem but a feature, it is advisable to mention it in the readme.

dirkf commented 2 weeks ago

This old upstream issue, with its relatives, is somewhat similar: user who specified a fixed --output value (in particular, without %(ext)s) was surprised when the final file had a .webm or .mkv extension as a side-effect of merging.
