[SOLVED] OSD causes live to stutter

[laffinet]

As the thread topic states, whenever the onscreen display comes up (changing a channel, displaying information) live TV stutters until the OSD is off again.

Any idea what I can do about this ?

There is something mentioned here (http://www.mythtv.org/wiki/index.php/XvMC#OSD) but I don't quite understand what I'm supposed to do.

Does it stutter the whole time the OSD is up, or just when it is fading?

You can disable the fade from your TV Settings -> OSD menu

Are you using a nvidia card? Have you tried enabling XvMC? If so, have you tried changing your playback profile to utilize XvMC?

I picked a simple black and white OSD with no fade. There is still some transparency with my OSD, but it isn't as graphic intensive I guess.

[laffinet]

Thanks. XvMC is enabled.

Have picked another OSD which fixed it for now.

Will play around with profiles when I get a bit more time.

I have the same issue as you - just out of curiosity, which OSD did you choose which worked?

[laffinet]

I'm not at home at the moment so can't check but I think it was called "mirror widescreen" or so.

Note: I have since discovered that this hasn't fully solved my problem, I still get the occasional stutter. Not as bad and as often, but still there. Might have to do some tweaking via profiles after all.

Well, for me I still suffered with the issue in HD. After a bit of tweaking, I now have another major issue:

<code>
root@kubuntu:~# cat /proc/driver/nvidia/agp/status
Status: Disabled

AGP initialization failed, please check the ouput
of the 'dmesg' command and/or your system log file
for additional information on this problem.
root@kubuntu:~#
</code>

I made a small change in my xorg.conf (Option "NVAGP" "3" had a "1") and now it works as it should.

So you got rid of the stutter ? What settings are you using ?

So you got rid of the stutter ? What settings are you using ?

I just got rid of my stuttering with this setup in my xorg.conf:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "UseEvents" "true"
Option "XvmcUsesTextures" "false"
Option "NVAGP" "3"
EndSection




I tried NVAGP 1 , but I could never get it to work. Then I used 3 and it worked. I never tried 2.

My xorg.conf is like the poster's above. I tried a few different OSDs and they all work flawlessly now. Yay!

I also reinstalled the nvidia driver recommended by Envy.

And now I get this in konsole:

root@kubuntu:~# cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Enabled
SBA: Enabled
