[Implemented] H.265 - High Efficiency Video Coding (HEVC) Plex Support!

Nope, Gotham is FFMPEG 2.0. There was a discussion about delaying Gotham and moving to 2.1 but that option was decided against due to significant issues with Gotham built using 2.1:

I'm yet another person looking for HEVC support.... Just switched out all my displays for 4K units and I want to switch to using x265 for encoding.


Too bad, seems we're going to have to wait at least a year, year and a half before seeing x265 support in Plex...

Does plex use xbmc as a player?

Does plex use xbmc as a player?

No but XBMC can use Plex as a Media Source.

I'd certainly like to see h265 support, even if I'm not in the market for a 4k display. Better quality/smaller transcodes of BluRay video would be great.

Would also be nice to see support for the new Google h265 alternative...vp9 is it?

No but XBMC can use Plex as a Media Source.


XBMC can use Plex as a source, but Plex Home Theater is also based on XBMC.

Yes based on XBMC but not actually using any XBMC you may have installed. Although if Aggregation was implemented I suppose it could use XBMC as a Media source as well.

Yeah. VP9 is also supported by ffmpeg 2.1, so we can only wait and hope

People keep talking about 4k video with regard to h.265.  What people seem to be missing is that at lower resolution it results in files that are about half the size of h.264 for similar quality video.  There's no denying that this would be valuable for many people.  Beyond the obvious value of simply needing less capacity to store one's media library, it also means less I/O to disk when reading things from that collection.  It is entirely possible that in turn could be of benefit for relatively low powered devices when applied to lower resolution streams.  Making claims that low-powered NAS devices couldn't handle it is premature if you don't know the level of CPU oomph required to transcode from it.  In any event, not everyone is running on a low-powers NAS device.

The reality is that both h.265 and vp9 are coming down the pipeline pretty soonish.  Plex being in a position to support those files when they start appearing in force is a smarter place to be than supporting them 6 months AFTER that date.

Also, members making pronouncements of what the dependency chain looks like relative to ffmpeg, XBMC and Plex doesn't meant a whole lot.  Dev say-so is more solid and real.  It doesn't make one whit of difference which code is based on which if a dev decides to go off and code something up.  The only place prognosticating on the topic will get us is to the realm of mental masturbation.  Let someone with authority weigh in.  Everything else (even this post) is noise.

The problem is that h265 HEVC requires far more computational power than h264 AVC.


Plex will not be able to transcode to h265 for quite some time, and since most target devices don’t support h265 yet it would have to transcode H265 to h264 the majority of the time.


I think it’s too soon.

I like this post for the term "mental masturbation" alone. :D

Everything else (the facts, the logic, the critical addition of another perspective, the self-deprecation) is bonus material.

already ave a lot of content in h265 now so it makes sense to support it at least in beta.

I'd appreciate a "Lab"/"Beta" function for HEVC, h.265 decoding :)

So because your hardware is too weak to support HEVC I shouldn't be able to use it either? 4K displays make up not even a fraction of a fraction of the display market so by your logic Plex shouldn't support 4K because it too requires a lot more CPU then 1080p.

I know that the're some people saying that H.265 is not needed and are crazy for asking. I, for one, am not crazy and I am asking that Plex proceed in implementing it as soon as possible.

I don't have any 4k displays. What I do have is a PC with an 8-core processor, 16gb of RAM and a kick-ass video card. My interest is purely in the fact the file size is smaller for the same quality video.

For those that keeping stating that it would require too much horsepower, The 1998 Pentium II that I have in basement will not run Plex either. Should Plex have to support crap hardware for every feature?

The answer is quite simple. If your hardware doesn't support H.265, then don't encode your video with x265, use x264 instead. Problem solved.

The answer is quite simple. If your hardware doesn't support H.265, then don't encode your video with x265, use x264 instead. Problem solved.

The problem is that even extremely powerful hardware will have difficulty transcoding to H.265 in real time, and very few clients support decoding it, so any media you have in h.265 will need to be transcoded to h.264 in real time, reducing quality.

It really is best to wait, for now.

But most movies are transcoded anyways: the client simply isn't capable for displaying the movie anyway, regardless if you transcode a full-HD to x264 or x265, simply because of size or the need of subtitles. So given that transcoding is going to happen anyway, it becomes more interesting because x265 is much more compact...
