Bug ID: 459925
Summary: VLC showing black screen instead video but Kaffeine
plays without problems
Classification: Frameworks and Libraries
Product: phonon-backend-vlc
Version: unspecified
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
Fresh Kubuntu 22.10 install. When Nouveau driver for NVIDIA graphics card was
used, there were no problems with video playback for some time (at least one
week everything worked ok), but then VLC black screen happened - no video, but
audio only. I didn't figure out cause of this.
Made another fresh Kubuntu 22.10 install, NVIDIA 515 driver install and got
black screen instead video immediately (no video - only audio sound), but
Kaffeine plays videos without problems – both audio and video tracks.
I figured out that problem is mainly with Xvid MPEG-4 Video (XVID), H264 -
MPEG-4 AVC (part 10) (avc1) and DivX MPEG-4 Video (DX50) videos. VLC - default
settings. Tried to change acceleration, etc, but no positive result.
Partial solution: When I uncheck Embedded video in VLC Video settings, I get
two VLC windows – first is VLC itself and second is video, which is played
normally. It spoils usability but at least I can watch videos in VLC now. What
kind of issues is this? KDE or VLC?
