format filter filesize not working

[jodersus]

Hi,
I am trying to use youtube-dl embedded in a simply python app that limits video download size.
I am using ydl_opts = {'format' : 'best[filesize<16M]'} literally copied from the README Format Selection Examples ([https://github.com/rg3/youtube-dl/blob/master/README.md#format-selection-examples]) but I get ERROR requested format not available:

>>> ydl_opts = {'format':'best[filesize<=16M]'}
>>> u = "https://www.google.es/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjvorrGg9XLAhXD1xQKHYwIDn0QtwIIHTAA&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Da1Y73sPHKxw&usg=AFQjCNEnG8QQmxXN9_8R1c3u-KhK5SrC3A&sig2=2UYmwCW9yFd-Wlh3rh_ZHA"
>>> ydl = YoutubeDL(ydl_opts)
>>> ydl.add_default_info_extractors()
>>> info = ydl.extract_info(u, download = False)

Any help will be greatly appreciated

Best,

filesize metadata is not present for videoaudio formats thus your condition fails. You can add ? to it to allow it to pass when no filesize is present: filesize<?16M.

Thanks. Can I not filter for video-only and audio-only formats separately, at least?

[dstftw]

Use grouping with parentheses.

[jodersus]

Ok, I'll look into that. Thanks!
