There is no libvdapu_965.so. |

It's part of the x11 overlay in layman |

Let's clear this up: vdpau and vaapi are two APIs for hardware video |
| 19 |
acceleration. The package x11-libs/libvdpau-va-gl implements the VDPAU api |
| 20 |
using VAAPI+OPENGL library calls, the package x11-libs/libva-vdpau-driver |
| 21 |
implements the VAAPI api using VDPAU library calls. So these two are |
| 22 |
effectively opposites. I was once wondering if it would be possible to |
| 23 |
bring these two to recurse... |
| 24 |
|
| 25 |
But let's get back on topic: VAAPI is pretty much only implemented on |
| 26 |
intel cards, and only on newer ones supported by the i965 driver. So you |
| 27 |
will definitely need VIDEO_CARDS="i965 intel" set. |
| 28 |
|
| 29 |
Next you need to install x11-libs/libva which will also pull in |
| 30 |
x11-libs/libva-intel-driver. Check with vainfo that this works. |
| 31 |
|
| 32 |
After that you can install x11-libs/libvdpau-va-gl and x11-misc/vdpauinfo. |
| 33 |
You also need to have the environment variable VDPAU_DRIVER=va_gl set |
| 34 |
somewhere. Drop this in /etc/profile.d/vdpau.sh: |
| 35 |
|
| 36 |
export VDPAU_DRIVER=va_gl |
| 37 |
|
| 38 |
Do the usual env-update && source /etc/profile, and then check with |
| 39 |
vdpauinfo that everything works. |
| 40 |
|
| 41 |
Now you can build all the packages you need with the vdpau USE flag. |
