First of all: thanks for the great software!
I am not sure if this is a bug or if I just misunderstand the video format selection process

  • I've verified and I assure that I'm running youtube-dl 2019.01.17
    (double-checked :-) )

What is the purpose of your issue?

  • Bug report (encountered problems with youtube-dl)

When using bestvideo[vcodec!=av01][height<=?1080] (Output A) it downloads format 137 (avc1) as one would expect.

But when using bestvideo[vcodec!=av01][height<=?720] (Output B) it downloads format 398, which is av01 and should not happen because of [vcodec!=av01].

The expected behaviour would be the download of format 22, whicht is not av01 and <=720.

I also tried without the trailing /best but the results are exactly the same.

I am terribly sorry if I just understood something wrong (and possibly wasted someones time :-) ) but I tested this very thoroughly, read through the complete section of format selection again and could not find an explanation for the strange behaviour.

And most redundantly: Thank you all again so much for this incredible piece of software, it's keeping my whole family sane ;-)

P.S.: I actually use -f 'bestvideo[height<=?1080][vcodec!=av01][vcodec!=vp9]+bestaudio/best' but removed the vp9 exclusion and tried to change the order to make sure it has nothing to do with that.

There is no such codec av01. You must either use its full name or "begins with" comparison.

Thanks for the answer. I just realized the name is actually av01.0.05M.08. Is there a "does not begin with" equivalent?
