[mythtv-users] judder problems with nvidia 358.16

Fri Mar 4 10:10:11 UTC 2016

As the original message got caught in the moderation filter, I'm reformatting it with more taken out to pastebin.

 To me, the likeliest candidates for the problem look like Compositing still being enebled somewhere, despite being disabled in xorg.conf and the xfce desktop configuration??

incorrect rtc permissions, although I don't see this fixing the incorrect refresh rates being consistently chosen.

All feedback and tips gratefully received!

 Thanks!

both set to 1920x1080, auto rate, default aspect.

I tried downgrading to nvidia 352.x but had problems compiling /installing against my 4.4.2 kernel. The pre-packaged versions gave me glx problems, so ended up with 358.16, which was the lowest version that built and installed. If this is the likeliest problem I will obviously downgrade the kernel.

Here is an example 25fps video

I was going to add further examples, but refresh is wrong for all framerates I have tried and the mail is getting long.

Compositing is disabled in xorg.conf and in xfce window manager tweaks, although mplayer complains:

 output from mplayer:
VIDEO:  720x304  25.000 fps    0.0 kbps ( 0.0 kB/s)
Aspect ratio is 2.40:1 - scaling to correct movie aspect.
VO: [vdpau] 720x304 => 729x304 Planar YV12 
[vdpau] Compositing window manager detected. Assuming timing info is inaccurate.

In MythTV I have set up separate GUI and playback modes... as instructed in the judder free wiki page and am using the vdpau high quality profile

Note that the refreshrate is not matching the framerate and that frames are being dropped. Also note the permission denied on the rtc
