jonkv - Let me get back to you on the whole profile. I found another one on the forums I want to tweak and prob going to start from scratch with the original. Currently testing.
What about using ffmpeg? I don’t know how to test that at all 
Transcoding the audio with ffmpeg should be something like:
ffmpeg -i inputfile.mkv -c:v copy -c:a ac3 outputfile.mkv
c:v means codec:video, and setting this to copy means simply copying the encoded video stream as it is. c:a means codec:audio, and AC-3 is Dolby digital. And it should work well with other containers as well (MP4 or whatever). Note that this changes the audio into AC3, but it should also be possible to keep the DTS track.
I just tested this on a file with H.264 video at 13 Mbps plus DTS audio at 1.5 Mbps, and it converted the file at 59x realtime speed using 70% of one core, so it is definitely very different from transcoding video.
Thanks for the response jonkv, but…
I got it! Just checked my logs:

Here are the relevant lines… (with the opening < removed so itll post…) I think I had a few issues. I went ahead and added hevc and h265 together (just in case it didnt parse them the same) any time I made an addition. I was also focused on the directplay profile thinking I wanted the stream to directplay… however that was incorrect. Instead I needed to focus on the transcode targets. When I looked at that video profile originally I was thinking it meant it would transcode anything in that list instead of saying these are the codecs the player can process. So I added both h265 and hevc to both transcode and directplay. I also added them to the codec profiles with upperbounds thatll work for all my media. Anyway, looks to be working!!!

Thanks for this! Good to know someone can figure it out even if the Plex team can’t. That might sound unfair, but Plex have had since at least October to offer support for CCU and we’ve heard nothing. Not even a seperate profile is pretty poor.
I have a CC2 as well, we’ll see if it explodes when I try this profile

Awesome, I’m going to try this out and see how it works on the built in casting on my P-55, will post back with results, really hoping to get HEVC sorted for my library!
So I added those lines, now plex shows as “Transcoding” then says Video is Direct Play and Audio is Direct Play. However, nothing plays and it just shows “buffering” continuously on the TV…

Works for me with CCU. Is P-55 some Vizio TV? Does that use Chromecast.xml? Don’t just add the lines, rather replace the entire Chromecast.xml with this modified code. I took the liberty of formatting the code and attaching a copy.
The whole point is that it shouldn’t say “Transcoding” at all. My Plex server says “Direct Stream”, which I think is correct as the intention is to just repackage the content.

Yeah, the P-55 is Vizio’s latest line that has Chromecast built in with 4K and HDR support, it definitely supports HEVC as well and has been updated to the latest chromecast version (1.21.75378). I’ll download and replace the Chromecast.xml, it’s definitely using that xml since it changes how things are played through P-55, so hopefully this one will be the magic bullet.
You really want a separate definition for the ChromeU.
Google should have added a header or something advertising the codecs, but you can make media servers detect a ChromeU in addition to a ChromeCast Classic and serve the right video streams to each.
http://www.universalmediaserver.com/forum/viewtopic.php?f=5&t=9130
So, tried using that xml and no dice, same problem as before, it says “Buffering” under “Chromecast”, then Transcoding… actually Transcoding (throttled)… and Direct Stream next to video and audio (I miss spoke earlier when I said “Direct Play” but it actually says Direct Stream), but my NAS is clearly not transcoding as the load does not increase any and the video never starts, just spins the loading/buffering icon forever.
I know the HEVC videos are playable as they can direct play on Plex Media Player on my NAS, the P-55 supports HEVC playback so I’m not sure what the deal is. Here is part of the log after trying to play.

Glad it worked for you hammy Nice to be able to give back something for once.
Dj - From what you posted it certainly seems like its missing some kind of support:
“INFO - [Chromecast] canDirectStreamVideo: false” also are you only trying to play 1080? Your log mentions that resolution… I never had a problem with that.
Oh and zurick… super useful info. TY for that.

Thank you, is there a way to know what profile Plex is using? Should I check the logs for that? I notice that there is a “Opera TV Web” profile and also profiles for Sony Bravia (my Smart TV) so I’m not sure which one to tinker with

I know it's saying it can't direct stream but other owners of this TV have had success with Plex direct playing HEVC content when altering the profile, like on this post: http://www.avsforum.com/forum/166-lcd-flat-panel-displays/2378658-official-vizio-2016-p-series-owners-thread-uhd-hdr-dv-no-price-talk-please-182.html#post43180674
I don't know what I'm missing but this sure is frustrating =/Just wanted to add the XML edits worked for me… Using lsio pms docker. It was driving me bananas …as it was pinning all 8 cores of my fx8350
Thanks

I banged my head against this for a few days as well, turns out the latest firmware on our 2016 Vizio P series ( as of firmware 3.0.13.5) disabled local HEVC streaming. I’m buying a CC ultra to fix it.
@Clmcm400 's code worked for me to get HEVC/H.265 directplay working on Chromecast Ultra too! Thanks a lot @Clmcm400!
I had to edit it slightly, maybe due to an update. Here is my full Chromecast.xml file, direct playing HEVC without transcoding as of Mar 1st, 2017:
