[X] I attached the backtrace in the case of a crash.

I also get some errors and it seems specific to this specific youtube stream somehow, can you reproduce this on any other youtube stream? I can't

heppens to all live streams

mrfragger commented 23 hours ago

yea if live stream it won't work but if it's a recorded live stream then no problem in mpv.conf

ytdl-raw-options = extractor-args="youtube:skip=hls"
ytdl-format = bestvideo*[height<=?360]+worstaudio/worst

This is likely due to broken DASH support in ffmpeg. Nothing to fix here.

dosent yt-dlp also have support of m3u8 manifests? why not use that

sfan5 commented 17 hours ago

ytdl_hook should be using that by default unless you have enabled use_manifests. However, IIRC in certain cases with some youtube content only DASH is possible.

solomoncyj commented 17 hours ago

oh wait yes the stream was in manifestless mode 🤦
