Description

Format selection with "tbr" is not working

It appears that selection of videos via tbr is broken. I have been testing this with a few youtube videos and it doesn't appear to be specific to a single video failing.

From the readme: "You can combine format filters, so -f "[height <=? 720][tbr>500]" selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 KBit/s."

If I attempt to use that specifier an error is returned: "requested format not available"

When I checked out the output of --print-json there are many entries with non-null tbr values, the example below should be a candidate for a valid video

You are applying format selection to video+audio formats represented by a single file. No tbr meta data is provided for such formats by YouTube thus you are getting no requested format available error correctly.
