HEVC coming to devices

Congrats on being the official 4K BluRay codec.

Cheers !!

There already is. But thats more for broadcasters than for optical media. They allow 4K@60 on the 4K Blu-ray, no need to use interlacing to get to that temporal resolution anymore, so they can just shove progressive on there. Discs usually have enough space, bandwidth is no concern there.

It seems like we can add the new iPhone to the list of HEVC playback devices. The iPhone 6's specs indicate HEVC decode + encode capability. Unfortunately, level support is not listed, and Apple has a history of poor initial implementations of codec features.

^^ That's huge news. That means OTT services like Netflix can start actually using HEVC in DASH as a real delivery option with tangible improvements over AVC in HLS or Smooth Streaming - one that will actually have a huge population of potential users.

Except for FaceTime, I don't see anything else relative to HEVC...or I missed something ?

HEVC FaceTime would indicate a mobile device being able to do realtime simultaneous HEVC encode & decode with at least 720p30. Fixed-function hardware is basically a guarantee here, especially as their new SoC comes with a huge transistor count boost. (Edit: huh, a 20nm commercial design can decode 10bit 4K 120fps with 0.5 mm^2 die area. )

I guess the the question mark is whether the capability will be accessible to 3rd parties (my search through dev docs currently says no), but I'm optimistic and hope that it'd all be a part of a future iTunes TV/Movies push alongside a future iPad/AppleTV/whatever.

And I certainly wouldn't mind having a home server be able to stream x265-transcodes to my phone for when I'm on the road.

Yeah...I guess so. I didn't try yet VLC for iOS but maybe this would be doable with that.

Do you have a citation for that? I couldn't find it on Apple's page.

Also, I've never heard of anyone considering* the use of interlaced for >1080p content. UHD should be a progressive only paradise.

* And we should threaten anyone who suggests otherwise with those zombie-killing baseball bats with bent nails shoved through them. And glower.

I wonder if the new video and picture captured in iPhone 6 are HEVC? I really wish the HEVC movement could start sooner rather then later, We have been stuck with H.264 Basic or Main Profile for far too long.

Another thing, WHY ANOTHER GOD DAMN Profile fragmentation, we have version 2 of HEVC..........

AFAIR both (i.e. H.265 and UHD) standards assume only support for progressive - interlace can be supported indirectly only - i.e. back to MPEG-1 times.

Software decoder based I would say...but this is a press release.

A Windows director tweeted that Win10 will have built-in HEVC decode.

Build 9841 (6 weeks old) of Windows 10 has native playback for HEVC Main and Main10 profile in MP4 container. I'm currently downloading the update which supposedly adds MKV container support.

I'm using a VM, so it wouldn't make sense to do speed comparisons myself, but I wonder how optimized the decoder is compared to LAV's.

Don't underestimate VMs; I got a faster memory benchmark inside a VM than on the hosting PC, using VirtualBox and Everest...

I believe they use HEVC encode only for facetime at the moment. It's highly unlikely their first gen hardware HEVC encoder can support 1080p60 at the quality they want.

This is interesting (from Qualcomm presetnation linked in this post). They actually state no Main 10 support (as opposed to the rest of industry that is conveniently ambiguous).
