I don't see any evidence of it downloading the full video? Just a slow download speed

You're right, tried downloading 10 seconds and it worked.
Is there a way to speed up the download speed?, 100kb/s is very slow.

[bashonly]

You could try downloading a different format, e.g. 140

Downloading with ffmpeg is naturally slow since ffmpeg is unable to abide by youtube's http chunk size limitation (for which they'll throttle your download speed when exceeded).

Sometimes a particular format will give a slow download rate, while others fare better (hence the suggestion).

Youtube also seems to be experimenting with throttling download speeds for iOS client formats, so you could also try --extractor-arg "youtube:player_client=web"

Still stuck at 100kb/s, even tried with:

-f 140 --extractor-arg "youtube:player_client=web" --throttled-rate 500K -r 5M -N 6

It's probably just this then. IIRC the http chunk size throttling doesn't apply to formats 18 and 22, if those are available / usable for you. You would be downloading video & audio and extracting the audio, but even so it would prob still be faster if you got a "normal" download speed instead of 100KB/s

It worked much better, the only problem is that sometimes they are not available or is not the best quality.
How one's can know what formats are not throttled by ffmpeg?
