Transcoding issue - Not sure if issue

Recently I enabled Hardware acceleration under transcoding. I have a  simple system and I have listed the core stuff below. This is just running server, nothing runs directly off of it over HDMI or anything else.

 

DX11VA Intel® HD Graphics 4600 (built on, set to 1024MB in bios)

Intel i7-4770s running at 3.10Ghz

16GB DDR3 Ram

Windows 10 PRO

 

Emby Server for Windows 4.2.0.4 Beta

 

The hardware transcoding was working a lot better than I anticipated. The server only has at most 5 concurrent users, so hardware acceleration would be my preferred choice.

 

But here is the issue. I just noticed that video that is stored in a MKV container and the audio is encoded as either DTS or DTS-HD, the audio will not down convert and the movie never begins. On one client that is an Amazon firestick 4k, I made sure pass-thru was not checked since the TV does not do DTS natively. 

 

If I try the same video using a web browser, I will get no container available and nothing will play.

 

Everything works perfectly if I software transcode and turn hardware acceleration off. So nothing is broken technically. But...

 

Should hardware acceleration decoding DTS or DTS-HD work with that Intel Graphics chip and processor?

 

Thank You.

Hi there, have you stepped through our hardware acceleration setup guide?

https://github.com/MediaBrowser/Wiki/wiki/Hardware-Acceleration-Overview

 

I have, followed all the tips and made sure correct drivers were used.

 

What I didn't see was how it handled or didn't handle audio codecs contained in the MKV container. Especially DTS. If fact all I really see is video encoding and it works on almost every thing I have, just not converting DTS or DTS-HD to say DD 5.1 or even 2 Channel Stereo.

 

But Ill keep looking.

It would only convert the audio if it's not supported by the device you're playing from. Does that answer your question about why it's transcoding or not transcoding?
