Can't download youtube videos with HLS enabled

[Tintin232]

bug description

When downloading certain videos, the download stops a second after it starts. This seems to be consistent with certain channels, for example, any videos that I try downloading from the SpongeBob SquarePants Official (https://www.youtube.com/channel/UCx27Pkk8plpiosF14qXq-VA) channel will fail. Likewise with other channels.

can you specify exact links that don’t work?

[Tintin232]

Actually, testing it now, ANY video I tried downloading (from many different channels) gets this issue.

seems like it only happens only when the hls option is enabled, try turning it off: https://cobalt.tools/settings/video#youtube-hls

Without HLS the download doesn't work though, keeps on pausing and restarting and ends with "Network Error".

Same issue here, except on my side, cobalt downloads a 0 B file.

This behaviour is akin to #816.

I affirm this only happens with HLS format.

Video: Sullivan King - Venomous (feat. Spencer Charnas of Ice Nine Kills) [Lyric Video]

The "Network Error"/"Failed" issue without HLS only occurs to me on longer videos, ex. ROBLOX_OOF.mp3 getting cut off after 23:22 (full length 1:57:48). Probably subject of #647.

fixed in api v10.4.3, try again and lmk if hls still doesn't work!

Seems to have worked for H.265; VP9 is still broken, downloading empty files.

I was able to get some downloads ~hour ago, now I am getting <5 KB/s downloads speeds for some reason. Could be high traffic on main instance or something. Nevermind, all works well now for me. Thank you for fixing the issue!

youtube doesn't have h265 streams (yet at least), what are you talking about?

[onegentig]

Apologies, I meant H.264. I was talking about this option:
