youtube-dl - select quality?

Post#1 by Rava » 12 Mar 2020, 08:08

According to the help info, there is no way of telling youtube-dl which audio and video quality it should download. [1]

Maybe one wants just to watch a silly clip (and later delete it) offline and one not needs the full-HD quality for that, so being able to e.g. choose 360, 480, 720 or 1080 would be a neat feature.

For now, it seems all that youtube-dl is able to do is always download the largest file / best quality.
Is there maybe a hidden parameter that would enable youtube-dl doing so?

_______________
[1] The only hit for quality is this:

Code: Select all

    --audio-quality QUALITY          Specify ffmpeg/avconv audio quality, insert
                                     a value between 0 (better) and 9 (worse)
                                     for VBR or a specific bitrate like 128K
                                     (default 5)
Cheers!

use youtube-dl -F first to get a list of the available video/audio formats

Example:

Code: Select all

guest@porteus:~/Test$ youtube-dl -F https://www.youtube.com/watch?v=0LyAey51CmQ

download whatever you want with youtube-dl -f <format code> <video address>

Quote from the page linked above:
You can merge the video and audio of two formats into a single file using -f <video-format>+<audio-format>
(requires ffmpeg or avconv installed),
for example -f bestvideo+bestaudio will download the best video-only format, the best audio-only format
and mux them together with ffmpeg/avconv.
