Porteus switched from youtube-dl to yt-dlp - and how to get the most recent version

[Rava]

When you interrupt a download and start it anew using youtube-dl it will continue the partial download.

yt-dlp seems to be unable to do so by default - at least in some cases.
Even when yt-dlp claims this

Code: Select all

    -c, --continue                  Resume partially downloaded files/fragments
                                    (default)
    --no-continue                   Do not resume partially downloaded
                                    fragments. If the file is not fragmented,
                                    restart download of the entire file

I realized that it will not continue a partially downloaded files/fragments. At least when I tried doing so on an https://www.cbsnews.com/news/ URL - maybe that was because of some "If the […]file is not fragmented, restart download of the entire file" issue?
Or was it because of the crypto+https:// part?

The cbsnews.com/news/ one was this

Code: Select all

yt-dlp -f hls-500+hls-audio_aac-English-1 https://www.cbsnews.com/news/president-joe-biden-taiwan-60-minutes-2022-09-18/

and it looked quite fragmented to me:

Code: Select all

What are your experiences with continuing a partial download using yt-dlp?

[Rava]

Only while I did my most recent download I realized something weird with yt-dlp:

Code: Select all

Do you see it?
I obviously download 2 formats - a video only one - 244 and an audio-only-one - 249.
Still it tells me this

[info] 9TCdf8xes1M: Downloading 1 format(s): 244+249

No, 244+249 are two formats, not one.
But whatever. That is so minor I not even bother to report that as a bug to the yt-dlp developers.
