Description

I have a youtuber which posts songs on a regular basis. He has a massive love for random special characters. Here are three failing URL's:

https://www.youtube.com/watch?v=dlhJsonLQ3c
https://www.youtube.com/watch?v=8GZsvUHJvfQ
https://www.youtube.com/watch?v=ykSMrgjSeGE

I've sampled the last one with two commands, one to convert to MP3 and one that doesn't. It fails extracting everytime I attempt something, which makes it tedious to extract a big playlist with these songs in them.

Thanks

He has a massive love for random special characters. Here are three failing URL's: https://www.youtube.com/watch?v=dlhJsonLQ3c https://www.youtube.com/watch?v=8GZsvUHJvfQ https://www.youtube.com/watch?v=ykSMrgjSeGE I've sampled the last one with two commands, one to convert to MP3 and one that doesn't. It fails extracting everytime I attempt something, which makes it tedious to extract a big playlist with these songs in them. Thanks

Just an added comment for this issue for anyone wondering: The issue is while converting in ffmpeg. The string fails because of special characters:

I ran this command:

C:\temp\playlist\test>C:\temp\ffmpeg -y -loglevel "repeat+info" -i "file:Teneneh - Rahim x Dallas B [Flow Promo] By 🇿🇿 Dj Akme 🇿 🇿🇿 🇿🇿 🇿🇿 🇿🇿 🇿🇿-8GZsvUHJvfQ.webm" test.mp3

And it works. However, the way that the youtube-dl exec hands off the string to ffmpeg, it fails everytime. Here is how ffmpeg interprets the filename, which might be the cause due to special characters:

Input #0, matroska,webm, from 'file:Teneneh - Rahim x Dallas B [Flow Promo] By ≡ƒç»≡ƒç▓ Dj Akme ≡ƒöÑ ≡ƒç║≡ƒç¼ ≡ƒç│≡ƒç¼ ≡ƒç╕≡ƒç▒ ≡ƒç¼≡ƒç¡ ≡ƒç╣≡ƒç┐-8GZsvUHJvfQ.webm':
Metadata:

So is the issue with the extraction part of youtube-dl? No, this works fine to pull the webm. The issue is post extraction and during conversion, but ONLY when using youtube-dl commands to invoke ffmpeg, as running the SAME command manually through ffmpeg handles the conversion well.

@dstftw Don't know if there's anything more you can do to investigate this, is there a way to strip special characters? Can we rename the file post extraction with a command? I'd really like to get this to work, because the workaround right now is that everything DJ Akme needs to be saved to a separate file, needs to be extracted manually and needs to be converted manually. Becomes pretty tedious a task to manage... PC's I use are in Canadian French for language. Could it be a language/formatting issue?

Also, reran your command: youtube-dl https://www.youtube.com/watch?v=ykSMrgjSeGE -x --verbose and it fails. Result below.
