Bug ID: 416825
Summary: VA-API can not be set / enabled in newer Kaffeine
versions
Product: kaffeine
Version: unspecified
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
The VA-API decoder cannot be set (enabled) in newer Kaffeine versions. The
corresponding argument "--avcodec-hw=vaapi" shows no effect. This problem seems
to affects most newer Kaffeine versions.
So long VDPAU is working properly this is not a drawback. Unfortunately VDPAU
seems to be on more recent Radeon (r600) MESA driver releases often broken. The
solution or workaround is to switch to the VA-API. This works perfectly in VLC
were in the settings the VA-API video decoder can be selected. After this, H264
videos can be played error free.
STEPS TO REPRODUCE (r600 based Radeon GPU system needed!)
1. Install Kubuntu 18.04 LTS
2. Install a current Kaffeine version
3. Update system, also to newer MESA versions
OBSERVED RESULT
H264 video files are displayed corrupted in Kaffeine when a driver with broken
VDPAU is used. A switch in Kaffeine to the working VA-API does not work, the
corresponding VLClib argument shows no effect.
EXPECTED RESULT
The "--avcodec-hw=vaapi" argument should be active and working. However, it
does NOT work.
