Ati driver 13.12 DXVA problem

With Ati driver 13.12 , ati6970 ,when i start DVBViewer for the first time, at every startup, i get sound immediately but black screen for 5-8 seconds. In Dvbfilter i see buffer overflow.

If after i start up DVBViewer i click on other channels, those one start ok, only first one is problem, SD,HD doesnt matter.

 

I find the fix:

1. update ati driver

2. In LAV filter, at hardware acceleration, set DXVA2 to COPY BACK instead of DXVA2 NATIVE.

 

In other codecs, like microsoft, arcsoft, cyberlink, because i cant set CopyBack in DXVA i get that black screen at every DVBViewer startup.

This latest ATI BETA DRIVER, AMD_Catalyst_14.3_Beta_V1.0_Windows_B22_March12

 

Fixed this problem.

 

Now, when i start DVBViewer every time, live image appear in one second with hardware acceleration in lav filter set to DXVA Native or DXVA Copy Back.

And with all codecs are ok, microsoft, arcsoft, cyberlink.

Problem fixed.
