Does the AMD A6-7310 support 4k dxva decode?

UPDATE It doesn't appear to be dxva2 even 1080p video.

UPDATE 2 It doesn't appear to hardware decode HEVC 1080p or 4k at all. Only H264 1080p maximum.

Looks like that's a low power Carizzo-L CPU from 2015 so it's on the border of having a new enough UVD version to suppose the HEVC format you seem to be interested in.

There seems to be conflicting information online whether it has UVD 4.2 or UVD 6.0 implemented, the latter supports some basic HEVC acceleration, the former doesn't even support H.264@4K.
 
What about DTS & Hardware Encode on the AMD A6-7310? Why is my DTS all distorted after being converted?

I left a clip to show what it sounds like but it's too large (What's the file size attachment limit?) if you have DTS capabilities on your setup you can probably diagnose it. The original was 24 bit & the converted file is 16 bit idk if that is the cause. I have this issue on all conversions to DTS, but not AC3.

I tested further & if it encodes 768kbps stereo DTS the distortion is gone but in 1536kbps 6 channel surround its distorted.

UPDATE
I found out it can hardware encode H264 without issue. It gains 20fps from 30fps to 50fps encoding high quality 1080p. Actually after further encoding it gains 5fps average, from 30 to 35 basically. It takes 12 minutes to encode a 22 minute file though which is good.

Still trying to figure out why the DTS is distorted. (Trying the DTS-passthru option in Handbrake now).

This is the Source audio data :

Converted audio data :

Audio

DTS Passthru on Handbrake yields this data. Why does it say Channel(s) : 2 & Channel(s)_Original : 6 channels?

VCE, hardware video encoding, is on the chip and seems to be supported by handbrake, although only unofficially for that age of chip:

AMD do provide audio processing capabilities in the GPU but they've had an uphill struggle to get any developers to implement it so I wouldn't count on handbrake having support. I'm not sure how useful it is for conversion anyway, it was more sold as audio processing. My guess would be that the audio problems are not a CPU/GPU related issue.

Have you checked whether the audio issue is a conversion or playback one by playing the converted file on another device?
 
Thank you for the reply buddy. I have not tested the DTS track on another device because I'm the only one with DTS decoding capabilities. It didn't happen while in stereo 768kbps DTS but did at 6 channel 1536kbps DTS. Why? If Handbrake does DTS Passthru it says Channel(s) : 2 Channel Channel(s)_Original : 6 Channels. Why? I think it sounds like it's in surround sound & the receiver reports DTS 3/2.1 surround.

2 things stick out to me the Codec ID : A_DTS or Codec ID : A9

I think the codec is causing the issue. The Source Codec is A_DTS & The converted files are A9.

A_DTS is the codec ID for a DTS-HD audio track.

If your selecting DTS passthrough that might explain why it's getting altered, try the DTS-HD passthrough option.
