Description korppi_metsa 2024-04-10 09:03:59 UTC

SUMMARY
Audio playback periodically freezes when using VLC backend. I haven't observed this with the Qt backend.

STEPS TO REPRODUCE
1. Set audio backend to VLC Player.
2. Stream a podcast for a while - longer works better for reproducing.

OBSERVED RESULT
After a while, usually around the 20-30 minute mark, playback freezes and has to be restarted via right click -> stream. No error log is produced, no crash occurs. It reminds me of when a video stops buffering.

EXPECTED RESULT
Playback should be smooth and not freeze or stop when using VLC backend.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Garuda (Arch Linux)
KDE Plasma Version: 6.0.3
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.3

ADDITIONAL INFORMATION
Qt backend works normally without this problem, but it gets annoying having to switch to it every time.

I've been streaming podcast episodes for several hours now from several feeds, and did not encounter any issue.
Given the fact that it's the backend which causes problems, there's probably nothing that can be done from Kasts side.  It's probably an upstream (libvlc) or downstream (archlinux packaging of libvlc) problem, or a problem with your network connection.

I'll close the bug report now because I simply can't reproduce it.
If you find a way to predictably reproduce the problem, then please feel free to re-open this bug report.
