Your HD movie was converted to stereo as well.  What this means is your system is reporting it can only accept a 2-channel input.  We are feeding it that and your receiver is then expanding that to 5.1 using one of the Dolby algorithms more than likely.

OK, but should the TV be able to play 5.1?

And why don't I see transcoding with the HD movie?

I really don't get it

 

Thanks for your effort

 

Edit

Here https://www.sony.ie/.../specifications are the specs for the TV..... what can you make of it?

The Sony's implementation of Android TV does not use the standard API's therefore passthrough audio does not work. This is the same issue with Kodi when they switched over to the standard Android audio APIs and one of the reasons I don't recommend the Sony Androids TVs. They also don't use the Android Display Mode API which allows apps to utilize dynamic refeshrate switching but that is another kettle of fish.

Something funny is still going on though as a Windows PC should have no problems downmixing DTS to 2-channel aac audio. The issue lies in the decoding of the hvec video which the Android TV should play directly. Is it not possible to stream copy the video while downmixing the audio?

We're looking into why the video doesn't stream copy in this case.  The audio issue is just a tangent and is not the cause of his performance problem.

I have the same problem with 4k files. They play smooth on my Sony Android TV with Direct play. Once I try and transcode any 4K its stops and starts every few seconds, I am checking my NAS CPU and Memory and they are on 30-40% so no overloading. I also have the Hardware transcoding on VA AVI. All FHD files are working like a breeze, I am moving from PLEX to EMBY because I feel their hardware transcoding works brilliant with my QNAP TS-453B. 

If only I can fix this 4k transcoding problem!

Can you please post the ffmpeg log from when this happens?

Hi, This stopped happening the day after I posted. I have just subscribed to emby Premier as I have witnessed a much faster response on my clients compared to Plex and scrubbing forward and backwards is very good and almost simultaneous. I am currently using QNAP TS-453B with 4GB ram as my server and have acceleration on as VA API. I tried clients on my LG old 4K TV and My new Sony Bravia 4K x85e Android TV, also on my galaxy note 8 and Apple TV. Loading and playing is much better and I really want to help make this system an even better experience.

I haven't tried the Google Assistant integration yet as I just subscribed and will definitely give my opinion on that.

Keep up the good work!
