    Just a guess: is your vdr user part of the "render" group?

    Your guess was right, vdr was not in render group. Now libvdr-softhdvaapi within vdr starts without errors. In my Debian system this output plugin is playing all the channels (SD, HD and UHD) perfectly even the 60 fps playback. No frame dropping or skipping audio.

    Thanks for help. We can close this topic.

    If I set plugin argument -v vaapi I see syslog error:

    Using Intel graphics driver i965-va-driver Version: 2.3.0+dfsg1-1 (intel-vaapi-driver)

    In Debian 10.1.0-amd64 I built libvdr-softhdvaapi from source

    In makefile I set flags

    VAAPI ?= 1

    PLUGIN = softhdvaapi


    and enabled DEBUG output flag in makefile also

    Installed the plugin and when I start vdr with plugin vdr stops with ABORT signal: codec: can't allocate HW video codec context err ffffffea

    Or I should set -v device in plugin command line option?

    In Makefile parameters were VAAPI ?= 1 CUVID ?= 0, but LIBPLACEBO was set. So Now it builds if I clear LIBPLACEBO ?= 0.



    -v vaapi

    When I run vdr with softhdvaapi (module from vdr-plugin-softhdcuvid) the vdr starts normally, plugin gets loaded and then the plugin crashes: code=killed, status=6/ABRT, see syslog.

    I am unable to find any info of Intel GT2-520 GPU decoding frames slowly. I made test where I used CVLC player with playlist containing some UHD DVB-S2 channels and this VLC is playing the channels perfectly, with 60 FPS @ 3840x2160. VLC output is not indicating any dropped or late frames - see vlc debug (-vvv) output.

    Is it possible to use VLC (cvlc) as VDR output?

    Ok, thank you for the hint.

    I also try to build softhddevice from different repository

    And this version seems to work better on most of the channels on UHD screen resolution. Video and audio is in synck, but in vdr menu of SoftHDdevice I see the count of dropped frames still counts up, but on syslog I can not see frame dropping, Only on UHD channels play I see "audio/alsa: avail underrun error? 'Broken pipe'" and frame dropping in syslog.

    I also add my build log of commit:

    commit 1fb6cb8d29345c17d66b77055b2b778655b8a918 (HEAD -> vdpau+vaapi+cuvid, origin/vdpau+vaapi+cuvid, origin/HEAD)

    Added DTS audio.
