Hardware-Accelerated Encoding HEVC

https://support.plex.tv/articles/115002178853-using-hardware-accelerated-streaming/

The article above talks about Hardware-accelerated HEVC 10-bit decoding with a 7th-generation Intel Core (Kabylake, 2016) or newer. But for hardware-accelerated encoding it only talks about h264.

Is it possible, or will it be possible to encode dvr/live tv in HEVC using intel qsv? I have a i7 kaby lake processor and when I use intel qsv 265 encoding in handbrake it is great quality in remarkably fast speed.

this is for when Plex is transcoding the content right? If so, while I don’t know what the answer is, effort might be better spent in finding a configuration that allows your HEVC content to be DirectPlay-ed instead of Hardware Accelerated transcoded. This might not be feasibly in all situations. I have a 4K HEVC piece of content that I use as ‘reference’ for my setup that I can DirectPlay on my Shield and as of recently on my LG TV (running the built in Plex app). At least I know that if I use MCEBuddy to convert any 4K content I might get to the following specs, I don’t have to worry about transcoding (hardware or otherwise)

I can directplay my HEVC files, I am trying to convert the files my HDHOMERUN (which is connected to plex dvr) creates into HVEC so they can be more easily streamed. It appears you can enable plex to automatically convert to h264 on the fly as it records but it doesn’t mention h265.

Yeah this would be fantastic.

Even if Plex doesn’t support it in their default transcode option you could write a simple script to post process the output from the DVR and use ffmpeg to encode it to hevc. I believe ffmpeg does support quicksync HW and Plex certainly allows you to add a “Postprocessing Script” under the DVR settings.

Is it possible to transcode live tv at h265. Currently most streams avg 39mbps. I would like to bring those down without losing quality.

Plex does not currently support encoding into x265.

Will it someday? Only Plex knows and they don’t tell us until they are ready.

I wish they would. Lol. I’m wondering how the new HDHR will support 6 concurrent streams on a 100mbps NIC.
