Hi. I own AMD Athlon64 X2 @2,6 Ghz with 4 GBs RAM and Radeon HD 5670 512 MB with AMD Catalyst 12.1 installed. The OS is Windows 7 Ultimate 64 bit.
I'm using the latest K-Lite Mega Codec Pack (8.20) and Media Player Classic HC 64 bit 184.108.40.20626 to play video files. I also enabled Hardware Acceleration (DXVA). Recently I tried to play 720p and 1080p 10-bit encoded MKV files and it works. But I also noticed that my CPU utilization was going high, about 80%-95%. Compared to when I played 720p and 1080p in 8-bit, they only took my CPU utilization about 10%-20%. So I think hardware acceleration doesn't work on 10-bit files.
My questions are:
- Is there any way to enable hardware acceleration on 10-bit encoded video files with my current HD 5670?
- If any, could you please tell me how to do it? What software (codecs and movie players) must be installed?
- If there isn't any, is there any GPU outthere which can play 10-bit encoded files with hardware acceleration?
