Video content randomly freezing and stopping with Jack

Unread post by tom__ » 2019-02-25, 02:16

Video content content appears to randomly start slowing down then completely stopping to a pause when using Jack Audio Subsystem. This happens consistently. I talked to a friend who knows a lot about programming with Linux audio subsystems and he said it's most likely an issue with how the program handles buffering. A lot of programs do no implement this correctly and fail like this when Jack is using an uncommon buffer size, such as used in high latency audio production setups.

Has anyone else experienced this, and also does anyone know a fix for this?
Thanks

This may be irrelevant. For one thing, I'm not sure exactly what you mean by "consistently". But, FWIW, I have similar issues with Pulse. But NOT consistently. I've always assumed the problem was either at the source or in the connection in between (like maybe a bandwidth issue) because a video on another page will play just fine. I might come back to the problem page the next day & it will work fine.

What I meant by consistently is that it is reproducible.

You may want to create an issue on our GitHub tracker with the exact environment you're working in and steps to reproduce, so we can put it on our backlog for things to look at. Unfortunately our de facto media component owner (Travis) currently has very little time to work on UXP and priority there is to get EME updated to Google's new API. But at least it will be known and others may be able to look at it too.
