Are there any relevant logs in server output? Which encoder are you using, and does the issue happen on software encoding as well?

galister commented 2 days ago

no relevant logs other than the socket closed ones from the prior disconnect. this is on vaapi, will test with x264, but the issue is quite rare, so not sure when i'll have more info
