I would say that, according to you card (Radeon HD 4000), you should use libva-xvba-driver, not vpdau. Sadly, both and libva-vdpau-driver[1] libva-xvba-driver[2] are not maintained anymore. You are on your own for now. Mesa recently added a gallium driver (libva-mesa-driver) which -afaik- works, but, according to this archlinux wiki page[3] you card is not supported. 1. https://cgit.freedesktop.org/vaapi/vdpau-driver/ (4 years without a commit) 2. https://cgit.freedesktop.org/vaapi/xvba-driver/ (5 years) 2. https://wiki.archlinux.org/index.php/Hardware_video_acceleration vmjl > While running: > > $ LIBVA_DRIVER_NAME=vdpau vainfo > libva info: VA-API version 0.39.0 > libva info: va_getDriverName() returns -1 libva info: User requested driver > 'vdpau' > libva info: Trying to open /usr/lib/dri/vdpau_drv_video.so libva info: Found > init function __vaDriverInit_0_35 Floating point exception (core dumped) > > The log has: > > May 28 11:22:52 beryl kernel: traps: vainfo[20535] trap divide error > ip:7f4ac8c0d2da sp:7ffef7cc3420 error:0 in > vdpau_drv_video.so[7f4ac8c0a000+17000] > May 28 11:22:52 beryl systemd[1]: Created slice > system-systemd\x2dcoredump.slice. > May 28 11:22:52 beryl systemd[1]: Started Process Core Dump (PID 20536/UID 0). > May 28 11:22:52 beryl systemd-coredump[20538]: Process 20535 (vainfo) of user > 1000 dumped core. > > Stack trace of thread 20535: > #0 0x00007f4ac8c0d2da n/a (vdpau_drv_video.so) > #1 0x00007f4ac8c101e8 n/a (vdpau_drv_video.so) > #2 0x00007f4ac8c10236 n/a (vdpau_drv_video.so) > #3 0x00007f4ac8c1040c n/a (vdpau_drv_video.so) > #4 0x00007f4ac8c111e0 __vaDriverInit_0_35 (vdpau_drv_video.so) > #5 0x00007f4acb6c71f6 n/a (libva.so.1) > #6 0x00007f4acb6c8017 vaInitialize (libva.so.1) > #7 0x0000000000401690 n/a (vainfo) > #8 0x00007f4aca7e5741 __libc_start_main (libc.so.6) > #9 0x0000000000401939 n/a (vainfo) > > The command seems to run fine on another machine with the same software, a > Core > 2 Quad Core Q6600 and an HD5570, but throws the divide-by error on the machine > with the HD4350. > > James > _______________________________________________ > Libva mailing list > Libva@lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/libva _______________________________________________ Libva mailing list Libva@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libva
