[SOLVED] Faulty video output with mpv/mplayer, vaapi

Hi,

I have a HD6870 with the proprietary catalyst drivers installed, and the packages needed to enable vaapi. The problem I have is that every video application like mpv, mplayer or whatever refuses to give me correct video output with vaapi. mpv for example gives me these errors, depending on filetype:

avi:

mpv doesn't crash, it just falls back to software decoding and gives me a grey screen when it's not fullscreen, and when it's fullscreen it tears a lot and flashes random grey stripes everywhere - sound still works fine. Any ideas on what can be at fault here? The only video output that gives me an OK image without tearing or anything else is x11, but it's really slow.

vainfo gives me this:

Re: [SOLVED] Faulty video output with mpv/mplayer, vaapi

Allthough i assume its not the case, if you have ffmpeg installed,
have a look at /try:

ffmpeg -psnr -i input.{avi,mp4}
ffplay -i input.avi

hth

EDIT: codefix

Uninstall libva-xvba-driver and do

export LIBVA_DRIVER_NAME=fglrx

Now try vainfo again. Instead of "Splitted-Desktop Systems XvBA backend for VA-API - 0.8.0" it should say "AMD MMD 1.0" or something like that.

Thanks, now VA-API at least gives me an output - but the video just flashes in fullscreen. I think another thing to notice here is that the video only plays correctly (gives me an output), if I play it on monitor 1 (I use three monitors) - but I can't get rid of the screen flashing.

EDIT: Fullscreen only flashes when I use mpv, with smplayer (+mpv) it works ok - but it lags from time to time. mplayer-vaapi won't give me a smooth playback either with -vo and -va as vaapi, and the screen also flashes when I'm using it.
Any idea on what's wrong? Is it my use of three monitors? This is really, really annoying.

Re: [SOLVED] Faulty video output with mpv/mplayer, vaapi

I'd say the crapiness of the catalyst driver is at fault. As it's a closed driver, not much can be done when something doesn't work. Especially in this case, catalyst doesn't actually have vaapi support, it's an internal wrapper to xvba.

Switch to the open driver, install mesa-vdpau, configure your players to use vdpau and enjoy proper support. Ok, before that, you can try mpv with --hwdec=vaapi-copy, but this eliminates a lot of the benefits of hardware decoding, as the system will consume significant resources copying decoded frames from the GPU to the CPU.

I actually tried the open source driver first, but I didn't know how (or find info) on how to configure for a triple-head set up. I will give it a shot again and try to configure it as I would configure a dual-head setup, but just with another third monitor. Thanks!

The open-source drivers works absolutely *fantastic* and solved  a bunch of other issues as well. Proprietary sucks.

Thanks!
