Bug#898575: In-memory cache grows almost without bound
The same with mpv 0.32 playing flac stream from online radio Config: cache=no demuxer-max-back-bytes=100KiB demuxer-max-bytes=2MiB Ram usage constantly growing (last seen as much as 700MB and cpu usage is growing with memory). Memory leak ?

I think (through some experimentation) that "--cache=no --cache-secs=10" will work on 0.29 and 0.27 giving the same behavior as "--cache=no" did on 0.27.

Can you see if > it has improved the situation? My situation is somewhat unusal -- I'm streaming from a local server that acts as a proxy, so I want to minimise prefetching (to avoid using up server resources). I doubt that the default configuration will suit me, but that's okay. What's not okay is that with older versions, I could simply tell my users to run mpv with "--cache no". With the new version, I'm going to have to ship a script. -- Juliusz

I think I agree that the manpage needs some clarification to note that the --cache option only affects the stream cache. In the meantime I uploaded mpv 0.29 which has adjusted the cache sizes a bit (although the behavior of --cache has not changed). Can you see if it has improved the situation?

The issue here was the size of > the demuxer cache (which caches already demuxed packets). This is completely unintuitive, and undocumented. From the manual page: --cache= Set the size of the cache in kilobytes, disable it with no, or automatically enable it if needed with auto (default: auto). The manual page needs fixing, at the very least.

That's correct. The --cache option only affects the stream cache (which is correctly disabled by that option). The issue here was the size of the demuxer cache (which caches already demuxed packets). This cache is not affected by the --cache option. Upstream enabled this cache and set it to a very large size. This was reduced in 0.29 thus mitigating the issue.

See these upstream issues about other people complaining about the same thing! https://github.com/mpv-player/mpv/issues/5359 https://github.com/mpv-player/mpv/issues/5652 https://github.com/mpv-player/mpv/issues/5799 However, in this commit the maximum cache size was reduced to 150MB, so hopefully 0.29 will improve this: https://github.com/mpv-player/mpv/commit/e167812406f97443d6422f4dd088a59db842f43a Thanks, James signature.asc Description: OpenPGP digital signature
Bug#898575: In-memory cache grows almost without bound
Package: mpv Version: 0.28.2-1 When streaming over HTTP from localhost, the in-memory cache grows seemingly without bound (RSS just got up to 700MB). Running with --cache=no does *not* work around the issue. Downgrading to 0.27.2-1 fixes the issue.
