- Issue started after the following happened: I think it broke after Rumble changed something?

Reproduction Steps

Trying to stream certain videos (Others work) from rumble.com with mpv --no-config, I also tried adding --profile=fast and --hwdec=yes.

Expected Behavior

The videos should be able to stream using mpv with yt-dlp.

Actual Behavior

When streaming videos from rumble.com with mpv and yt-dlp the video will be a slow moving and blurry slideshow while audio works as expected. When downloading the video with yt-dlp and then watching it with mpv it will work.

Log File

output.txt

Sample Files

The clips from the Jimmy Dore consistently reproduce this, for example the three most recent ones. (No comment on the videos since I haven't watched them)

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.

From your logs I see that yt-dlp extracted video that is 0.5 fps.
This is probably why video looks like slideshow.

Looking into what yt-dlp extracts from url is below. But mpv incorrectly selects 180p video by default.

mpv uses bestvideo+bestaudio/best by default.

$ yt-dlp -f 'bestvideo+bestaudio/best' -g https://rumble.com/v6tuamx-tim-dillon-schools-unbearable-cnn-host-on-basic-comedy-facts.html

https://1a-1791.com/video/fww1/64/s8/2/z/z/k/N/zzkNy.Gaa.aac

Using recommended format by yt-dlp selects 1080p video.

$ yt-dlp -f 'bestvideo*+bestaudio/best' -g https://rumble.com/v6tuamx-tim-dillon-schools-unbearable-cnn-host-on-basic-comedy-facts.html

Fix

Force mpv to use recommended format bestvideo*+bestaudio/best by yt-dlp.

$ mpv --no-config --ytdl-format='bestvideo*+bestaudio/best' https://rumble.com/v6tuamx-tim-dillon-schools-unbearable-cnn-host-on-basic-comedy-facts.html

[orbea]

That works, thanks. Why did it work for me if I used yt-dlp to download the video rather than using mpv to stream the video?

[e2dk4r]

I worded confusingly that yt-dlp selects 1080p video by default. My previous comment now edited to clear confusion.
