Mythfrontend crashes if libva-vdpau-driver is installed

Reported by: bjoernv Owned by: Mark Kendall
Priority: minor Milestone: 31.1
Component: MythTV - General Version: v31-fixes
Severity: medium Keywords: frontend, vaapi, vdpau
Cc: Ticket locked: no


Mythfrontend crashes on startup if the driver libva-vdpau-driver (VDPAU Backend for Video Acceleration (VA) API HW video decode support) is installed. After uninstalling libva-vdpau-driver startup is normal. The bug may depend on Nvidia graphics cards. I use a Geforce GTX 1050 Ti with the Nvdia proprietary driver 440.82. A debugging protocol is attached.

rpm -q libva-vdpau-driver 
Wenn 'vaapi' kein Tippfehler ist, können Sie command-not-found benutzen, um das Paket zu finden, das den Befehl enthält, z. B.:
    cnf vaapi
bv@cecilia:/data2/rpm-bjoernv-repository> vainfo 
libva info: VA-API version 1.6.0
libva info: User environment variable requested driver 'vdpau'

No obvious problems with this for me:

mythfrontend version: HEAD -> master [v32-Pre-e65f9155697]
Qt version: compile: 5.12.5, runtime: 5.12.5

OpenGL: OpenGL vendor        : NVIDIA Corporation
OpenGL: OpenGL renderer      : GeForce GT 710/PCIe/SSE2
OpenGL: OpenGL version       : 4.6.0 NVIDIA 440.64

rpm -q libva-vdpau-driver

but this box is using NVDEC and does not have VAAPI hardware:

[AVHWDeviceContext @ 0x16fe980] libva: va_getDriverName() failed with unknown libva error,driver_name=(null)
[AVHWDeviceContext @ 0x16fe980] Failed to initialise VAAPI connection: -1 (unknown libva error).

VAAPIDec: VAAPI functionality checked failed

libva-vdpau-driver doesn't seem to be available on ubuntu anymore. I might just give openSuse a spin:)
