My format string:
u'-f', u'bestvideo[ext=mp4][height=480]+bestaudio[ext=m4a]/bestvideo[ext=mp4][height>360][height<=480]+bestaudio/bestvideo[height<=480]+bestaudio/best[height<=480]/worst',

Breaking that down:
bestvideo[ext=mp4][height=480]+bestaudio[ext=m4a]
bestvideo[ext=mp4][height>360][height<=480]+bestaudio
bestvideo[height<=480]+bestaudio
best[height<=480]
worst

The goal here:

1. If there is a 480p mp4, take that.
2. If not, then if there is an mp4 better than 360, take that.
3. Otherwise, since conversion will be needed, take the best up to 480.

This CBS recording of Stephen Colbert has these two formats:
hls-1332 mp4 768x432 1332k , avc1.77.30, mp4a.40.2
rtmp-1928 flv 848x480 1928k

I want that hls-1332
I get the rtmp-1928

The flv to mp4 conversion is time consuming, noisy (maxes my fan), etc. 432p is "good enough".

The separation of best video + bestaudio is needed for dealing with youtube's dash. But here, the 432p should match
bestvideo[ext=mp4][height>360][height<=480]+bestaudio
and it has the best audio already in the track.

Unfortunately, it's not working.
I don't know what I'm doing wrong.

CBS does not provide any bestvideo format thus bestvideo expressions won't match anything falling back to best[height<=480] that correctly matches rtmp-1928 as the best format among formats with height under or equal to 480. Add [ext=mp4] to best if only interested in mp4.

Ok, then 1, I know what to do, and

2: What the heck is "best video" then? I see about 15 different video formats in that list?

[yan12125]

best video means the best video-only (no audio) format. As all formats provided by CBS contain both video and audio, they don't fit the term "best video". Few websites provide such formats, of which YouTube is the most well-known one.

Okay, thank you.
