Youtube Video Quality Sorting Incorrect

[zx2c4]

youtube-dl seems to download the 1280x720 version when a 1920x1080 version is available. What gives?

Here's what it chooses by default:

zx2c4@thinkpad /tmp $ youtube-dl --get-format https://www.youtube.com/watch?v=eYztYCbV_8U
136 - 1280x720 (DASH video)+140 - audio only (DASH audio)

It seems to me that the superior video resolution of 137 combined with the superior audio quality of 22 would be the best.

What's wrong with the auto-selection algorithm?

Bitrate takes precedence over width and height.

[zx2c4]

@dstftw Strangely I don't think that bitrate is even correct. The resultant file for the 1080p version is in fact larger.

I don't think that bitrate is even correct

FYI: There was a long debate without a conclusion at #6018

[zx2c4]

No what I mean is that the displayed bitrate just isn't correct. I don't think it's a matter of differing codecs or something.

[yan12125]

Well, the bitrate value is provided by YouTube.

This video is unlisted, maybe that's why it's treated differently by YouTube internally.
