[Solved] ATI APU - DXVA2 decoder stopped working (1 Viewer)

[Olli123]

Hi there,

after updating my ATI catalyst driver my TMP stopped working.

After spending the wohle day with it, i was able to identify the problem:
It seems that my hardware decoding DXVA2 is not working anymore.

I´m using a AMD APU A6-3500 on Windows 7 with LAV codec.
Trying to start a video with windows media player just crashes or give my strange errors.
When i set hardware decoder (inside LAV settings) to :
- DXVA copy back, the video starts (i can hear sound) but the screen is totaly green.
- DXVA native is complety not working.
- settings to None makes me able to start the playback.

I also testing it out with media player classic (which is using DXVA1) works fine.

Only the DXVA2 is not working anymore. By the way: It was working fine for years before.

So with that problem i figure out that my "Leistungsindex" tool from windows also stopps working when trying to test media performance.................

At first I loaded a lot of ATI drivers because i was thinking about a driver problem.

Right now i´m totaly out of ideas.............. Maybe hardware is broken?
Maybe it is a problem with my directx?

Can anybody help me with this?

I'm not an expert but if I wanted to eleminate hardware malfunction case I'd revert to previous drivers and check if alll is working.
My guess it's all because of ATI drivers since they are known crap.

Not possible.....
No restore point made.....[emoji20]

I meant remove current drivers -> install previous ones. Not systeme restore. I'm sure they could be easily found in internet.

Yes, problem I don't knew on which version I was before...... I already tried an alternative version.... Same problem....

 

[Edalex]

ah... you could also try to reinstall LAV.
Or use another decoders. BTW I can't agreee that MPC have DXVA1 since it's mostly XP case. I'm using only MPC-BE filters even in MP personally.

I have tried 3 different LAV versions already. Also MS-DVT decoder and ATI decoder are not working.
I'm not an expert with that codecs.. As far as I know Windows XP only supports DXVA1 but I'm not sure.

Yes, XP supports DXVA 1 and does not support DXVA 2.

But topicstarter has win7 according to specs

 

[Olli123]

Yes I'm on win 7 32bit.
And dxva2 was running fine the whole time.
I can image that my gpu unit is damaged. But how can I confirm this for being sure? Using a benchmark?
