Pruning transcoding temp files

[Steve E 2]

Emby 4.8.11.0 + win 11 + hd homerun for live tv

Whats the right way to  manage the "transcoding temporary files" folder?
Files keep piling up in them until switching the channel off

I tried this

emby server > live tv > advanced > live stream buffer size limit (hours) - set at 1

emby server > transcoding > transcoding temporary path - set and excluded in realtime anti virus scans

Thanks

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

I reviewed your live tv setup docs

https://emby.media/support/articles/Live-TV.html

The homerun and tv guide work fine, and picture beautiful,  but I didnt find instructions for cache management

I set these in the admin gui to keep the trancoding temp files to an hour

emby server > transcoding > transcoding temporary path - set and excluded in windows realtime anti virus scans

emby server > live tv > advanced > live tv buffer size - set at 1 hr 

I'd like to set it for size rather than hours, but dont see a setting for that

Then clicked on a channel and watched something

In the transcoding temp folder two directories were made

The one with the long number works fine - after an hour the oldest files start disappearing

The other one keeps growing

Either I did something wrong, or something's not working right

OK that one is specific to the playback transcoding, not the actual live stream. Currently for playback transcoding of live tv, these segments don't get cleaned up until playback has finished, but this is something we plan to improve on in upcoming updates.

For playback transcoding of non-live tv content, that does support cleaning out segments during playback. Live TV is just a little bit more complex so it hasn't been added there yet. Thanks.

Hmm that's confusing ?? why is that setting in Live TV section ??

If it does not control that ?

There's two transcoding temp entries. One is for the shared buffer, and this does support the size limit. That's what that option applies to.

Then there is one for active playback session of that buffer.
