Quicksync not working on A770

[leone145]

Hi, I am using an A770 now and the Quicksync hardware encoding is not working.

The apps I've tested are OBS, Handbrake and Outplayed. Both H264 and AV1 hardware encoding are not working properly on those apps.

I am not sure when did it start, I bought my A770 in mid-July, and it worked back then (with driver ver. 4576 or 4576 I think). I haven't recorded videos for a while since then. 

Now when the recording starts, using Windows task manager, I notice only a short period of utilization on both video decode and processing.

For converting videos using Handbrake, the encoding status shows its avg fps is 1 and it takes forever to complete the conversion.

For OBS and Outplayed, the output video is full of freezing and lagging.

I have tried to install and re-install drivers in the following order: 4578 > 4644 > 4575. Each time uses DDU in safe mode to uninstall the previous driver first, and always enable the clean install option in the driver installer. I try my best to close applications and programs as many as I can before installing the driver. After the installation, I always click the restart button in the installer before I test it.

Details of my setup:
CPU:: 13600kf

MB: MSI PRO Z690-A DDR4, BIOS ver. 7D25v1D
GPU: Acer predator arc A770 16g

OS: Windows 10 Pro 19045.3324

DDU: 18.0.6.5

OBS: 29.1.3
Handbrake: 1.6.1
Outplayed: 105.0.4470
Resize-BAR is enabled as shown in GPU-Z 2.54.0.

If you need a sample of recording/video conversion, I can provide it privately.

Please let me know if you need more information.

Hi Andres,

Thank you for the hard work from you and your team

After a clean re-install of the driver(ver. 4887) and OBS(ver. 30.0-rc1), my problem with OBS has been solved.

For Handbrake, I found tuning off the filter "Denoise" solves the problem. 

However, Outplayed(ver. 108.2.4611) is still not working.

I will post an update if I can fix the problem.

Hello leone145,

Thank you for keeping me informed.

Happy to hear that after the graphics clean installation, the OBS issue got fixed, and by turning off the filter "Denoise" solved the Handbrake problem.

Since Outplayed(ver. 108.2.4611) is still not working, I recommend you to contact the app developer for further assistance, as seems the issue is the app itself since we couldn't replicate the issue.

Let me know if you have further questions.
