 Posted: Sat May 16, 2015 7:27 pm Post subject: PureVideo/UVD/AVIVO support, what graphics card? |
 |
|
I have a GeForce GT 630 graphics card. I don't need good 3D acceleration, but I need accelerated video decoding support for playback of normal video. GT 630 provides this. However, the nvidia proprietary driver suffers from tearing, and no matter how I try to correct this, it is always still present in some form of another, vsync is simply ignored by the binary blob driver in some cases. As for nouveau, I have a different problem, the system is simply unstable. I don't even get a kernel panic, the system just freezes with no warning whatsoever, the system is not really frozen, it is just unimaginably slow. The mouse cursor can still be moved, but it will move something on the order of one pixel every 15 seconds.
However, that is just background information and besides the point.
I need a different graphics card. What graphics card(s) are known to have good support for Gentoo, with no known issues regarding hardware accelerated video decoding? Should I buy some AMD graphics card? How good is the AMD support?
The requirements are simply:
* vsync must work properly, no tearing is acceptable for video playback.
* Hardware accelerated video decoding must work.
What card, if any, meets these requirements?
I don't care about anything else. |

Hello deltamalloc,
I think you should try again with your nvidia card. I think disabling things like Composite/Xinerama is a good first step. I use the following xorg.conf, maybe it gives you some ideas what your xorg.conf could look like.

I'm pretty sure I've tried both before, but at least I have tried it again now, and the tearing is still there.
I have altered my X config based on yours, it is now as follows:
| Code: |
Section "Extensions"
Option "Composite" "Disable"
EndSection
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"

EndSection

Option "UseDefaultFontPath" "false"
Option "AllowMouseOpenFail" "true"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
Option "DefaultServerLayout" "X.org Configured"
Option "Xinerama" "false"

I can verify that Xorg.0.log states:
| Code: |
[ 170.874] (**) Extension "Composite" is disabled
[ 170.846] (**) Option "Xinerama" "0"
|
I can also verify that in nvidia-settings I have "Sync to vblank" enabled, "Allow flipping" disabled and that I have "high quality" set to the highest setting.
None of these make no different, there is still tearing.
Are you sure that you don't also have tearing? Please note that it only shows up on certain video files and during certain types of animations. |

ISTR you don't want to enable "sync to vblank" in the driver, as the xorg server does it nowadays.
Can't hurt to try it without, anyhow. |

Thanks for the advice. Sadly I've tried that numerous times already. |
