H265 HEVC Transcoding issue with iGPU HD 6000 in Proxmox

[AlexSol 1]

Hi!

Maybe anyone faced the same or similar issue and can show me the direction to solve it.

I faced the issue that Emby can't decode H265 (HEVC) on my hardware that suppose to do it.

My hardware:

Intel NUC 5I5RYH (Intel Core i5 5250U, Intel HD Graphics 6000).

I use Proxmox. Emby installed via LXC.

Hardware acceleration works fine as long as it is for H264. It works via Quick Sync as well as via VAAPI.

But recently I tried to play HEVC movie and faced issue that direct play works fine but any video transcoding (bitrate limit) leads to full stop.

As far as I know my hardware must be able to decode HEVC well. Emby shows me such an option in advanced settings. 

I attached a few logs:

1) Hardware detection log

2) Emby server log

3) Transcode H265 -> H264 log (with issues using Quick Sync)

4) Transcode H264 -> H264 log (no issues using Quick Sync).

There is also no issues H264 -> H264 using VAAPI but didn't attach the log.

I do not believe your iGPU can handle Hevc files.

Your CPU is a 5th gen. CPU.

And HEVC is only supported with 6th gen and after.

It is not the question of "believe". It is fact that it can and it do it well. It had to be obvious based on the fact that even Emby itself detect such an option.

The only question why it doesn't work in Emby.

The Broadwell series with iGPU HD 6000 can't "encode" to HEVC but decode it fine.

+ I did decoding with low-level tools back in past when I been working in video editing on this NUC for my software projects.

P.S. I don't know whether you need any proofs except my past experience but here a few links if anybody interested: 

1. HEVC in Broadwells

2. wiki

You might be right, but dev's will need to answer as it see this in your logs.

Sure, thanks, let wait for dev's.

Well, I've never figured this out so I just change my hardware.

Hi, what are you going to change to?

I sold my Intel NUC with 5th gen CPU.

I build a completely new server/PC based on 12th gen i3 12100.

Now everything works smoothly.
