any workaround for this youtube-dl bug?

newbiesforever · 12-11-2022, 03:39 PM

I have tried to use youtube-dl -x to download the audio from some videos. It is giving the following error message:

Code:

This makes youtube-dl useless for the moment to me. Any ideas?

Good luck.

Might be an old version of Yt.

in addition to above your code box shows you can run that command with verbose to get more info

yt-dlp version 2022.06.29

Didn't know that.

aus9 · 12-14-2022, 12:53 AM

debian is https://packages.debian.org/bullseye/youtube-dl v 2021.06.06-1

mine comes from MX distro and may be out of date

upstream https://youtube-dl.org/
v2021.12.17

pan64 · 12-14-2022, 01:14 AM

just some background information: youtube modifies their services continuously (you can say improve them if you wish). Therefore, the downloader must somehow track these undocumented changes. Youtube doesn't really care that the downloader works (or is compatible) either. So better to use an uptodate version, as it was suggested (Make sure you are using the latest version) or use a better alternative (see post #2)

business_kid · 12-14-2022, 04:02 AM

This usually does it

Code:

sudo youtube-dl -U

I prefer yt-dlp because it doesn't succumb to youtube's bandwidth-limiting tricks nearly as much.

+ one for yt-dlp

You can always scrape the virtual url for the video that you wish, and manually dump the audio from it. Use your web inspector or python script etc.

I just looked at the video you are trying to get.

https://m.youtube.com/watch?v=xfYS9ZE7-uo

Format 140(m4a)

Code:

url="https://rr4---sn-vgqsrnes.googlevideo.com/videoplayback?expire=1671049780&ei=1N2ZY9__Ovew2_gPtIutqAI&ip=108.188.145.145&id=o-AI08cDxwhq9YikeO9csoWPxZZ60itX-1XS5ftuvhIMuc&itag=140&source=youtube&requiressl=yes&mh=PV&mm=31%2C29&mn=sn-vgqsrnes%2Csn-vgqskn6z&ms=au%2Crdu&mv=m&mvi=4&pl=21&initcwndbps=1205000&spc=SFxXNnT25xTfHI07QonbbpwZ6_oXtWs&vprv=1&svpuc=1&mime=audio%2Fmp4&gir=yes&clen=33088035&otfp=1&dur=2044.447&lmt=1625421874993145&mt=1671027694&fvip=3&keepalive=yes&fexp=24001373%2C24007246&c=ANDROID&txp=7211222&sparams=expire%2Cei%2Cip%2Cid%2Citag%2Csource%2Crequiressl%2Cspc%2Cvprv%2Csvpuc%2Cmime%2Cgir%2Cclen%2Cotfp%2Cdur%2Clmt&sig=AOq0QJ8wRQIhAOwNAR2XJtJzwqjcXDHFXmU6zf4_Ydgf5IzhwIm1k7Y5AiAxEUEiwTFnMTFsymw9HeF73TBi9drAtO9ZJyUkTILZ_w%3D%3D&lsparams=mh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps&lsig=AG3C_xAwRAIgV1ZqtWJX-864BPBnZwjXYVL8-Q53lUpuFaubmRiKENYCIDiRPmYSas8ALDOKwuLBRy8a1qZdThlkuLsNWraZzJii"

ffmpeg -i "$url" -vn -c:a copy myaud.m4a

That virtual url is probably only good for a bit. But, I was able to download it.

I find this to be more evidence that Youtube is at fault: on further attempts, I find that sometimes the audio downloads normally; and sometimes it fails with that error message . It's unpredictable.

you must not use sudo with that downloader, that is pointless

business_kid · 12-20-2022, 03:45 AM

Not on my box. Youtube-dl is in /usr/local/bin.

And? why did you post that?

hish2021 · 12-20-2022, 09:41 AM

Code:

-U, --update                         Update this program to latest version.
                                     Make sure that you have sufficient
                                     permissions (run with sudo if needed)

^ from the GitHub page.
I download the binary to ~/bin and run it from there. Then, youtube-dl -U is enough; no sudo.

I now use yt-dlp. Same there.
