yt-dlp support

[mornroc]

I downloaded yt-dlp and added it to my system PATH variable. Is there anything else that needs to be done to use it? Any variables in .env that need to be changed? For some reason it doesn't seem to be using it.

I am using the v2026.03.17 release of the discord bot. Everything else seems to work. it connects, ingests my token, I can use slash commands. I see in the console log 403 errors.

Snips of log:

"403 Forbidden" means the link to the youtube track had restrictions. Acording to your log yt-dlp is indeed unavailable to the bot (it just tried kkdai parsers). Yt-dlp should be in PATH - it's enough for the bot to use it.

This is how yt-dlp is called

melodix/pkg/music/parsers/ytdlp/link.go

Line 16 in 5ddc171

ytdlp := exec.Command("yt-dlp", "-j", "-f", "bestaudio", track.URL)

It's the similar way you would do in terminal - check if yt-dlp can be called directly from there.

If you still are having issue - there is a Discord support server link (check Readme).
