Sample Files

No response

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• 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]

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]

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.

oh wait yes the stream was in manifestless mode 🤦
