Could you post the log?

Could you post the log?

mpv.log

I don't see a write request in that log; are you sure you dumped the cache while outputting the log file?

In any case, is the audio track included if instead of using the script you run

async dump-cache 0 no file.mp4

either through the console or with a keybind?

ctrl+Z to start dumping, ctrl+X to stop, maybe I shouldn't use ctrl+X to stop? BTW，I noticed that if I don't stop the dumping, the file on disk is a bit smaller (9,699,372 vs 9,769,038), is that matters?

I'm sure, here's what I did: a. del the mpv log file b. open a stream video via mpv c. ctrl+Z to start dumping d. ctrl+X to stop it e. exit mpv then I got a muted video file, and the log file.

ran the script in mpv console, it printed this: Snipaste_2023-11-27_17-01-31 and got the same muted file (the same size in byte).

I read the "dump-cache" part of mpv wiki, and tried to run the followed script in console:

dump-cache 0 10 f:/file.mp4

then I got a video file with no audio.

So, I think there's something wrong with the mpv "dump-cache" command?

This script wraps dump-cache so if this issue happens when not using streamsave and instead using dump-cache directly in mpv then yes it's potentially a problem with mpv. I still don't see the recorder being initialized in your log so if you report it on their issue tracker I would recommend you produce another log file while also running mpv with --no-config from the command line.
