We already have some internal prototyping for allowing codec specific quality settings (each hw codec implementation does this a bit different), so this is at least something we're having in the pipeline, but I cannot say anything about a timeline for this. @Luke

Yes he has a lot on his to do list, but perhaps later after some other things. Thanks.

The upcoming Emby Server 4.2 release will have improved hardware transcoding support for both RockPro64 and Raspberry Pi. Thanks guys.

Just an update on this.

 

Have been using my Intel i5 in my media server up till now but was getting slow / stuttering with large transcodes / 4k mainly and all cores at 100%.

 

Bought a 1050ti, installed the patch to remove the 2 stream limit and tested 4 X 4k transcodes and all 4 played without issue, GFX at aroung 70%.

 

Very happy with the purchase.

I just added a GTX 1060 to my server, thinking that it would handle HEVC media better than my Threadripper. To my amazement, there was no difference. Except that using NVENC/NVDEC is almost unusable when playing in chrome (slower transcoding and freezing playback). Are there expected improvements to this in 4.2?

Please see how to report a media playback issue. thanks.

I figured that was coming. I was intending to, I'm just in the middle of a bunch of things. When I'm finished, I'll try to run some specific testing and post my results with logs  :)

all Intel processors from the last decade or even earlier use speculative execution, and thats where the exploits have been discovered.

1060 is a pretty weak card no?

It's a pretty good card, but there are some bugs with how the server is handling HEVC over HLS, which appears to be much worse with HWA. So for my present usage, it's not practical.

There is no such bug. HEVC over HLS is not intended to happen at all. That's the actual bug.

That's what I was referring to. And I was adding that when I tested HWA with my GTX 1060, I had more videos exhibiting the problem, than I do with software.
