I just wanted to say awsome work

HEVC playback sweat as smooth on my AMD A10

XBMC 14 Alpha1 FTW

So my A10 will play h.265?
Did not think it was good enough.

[RockerC]

I have found these HEVC / H.265 samples for you guys might want to see what all the fuzz is about:

MPlayer and Linaro usually also have good sample collection but looks like no HEVC / h265 yet

As already mentioned FFmpeg's HEVC sw decoder is still new and will get better/optimized over time

I've been using the nightly builds to play Ultra HD (4k) hevc files for a few weeks and the pace of development has been impressive. Performance went from ~20fps to >60fps in a week or two's worth of updates late in July, this is with an overclocked i7 at 4.6Ghz which is now just fast enough for most of the UHD files I'm working with.

I have the BBC test transmissions from the World Cup, their Commonwealth Games transmissions and some other football matches that have been testing UHD. Also various recordings from the satellite UHD test channels running.

Sadly in the last week or so it all stopped working on Ubuntu, the current Mac version still plays ok.

I still have this version from the Ubuntu 64bit PPA which works well:

Version: 2:14.0~git20140806.0200-54baec4-0precise

Yet this one on another PC that used to work does not:

Version: 2:14.0~git20140820.0500-40ce5b3-0trusty

Is there a way to pull down specific versions from the Ubuntu PPA so I can narrow it down some more, I've tried but there only seemed to be the one previous version available.

To be a little more specific hevc does still work, the usual BBB and Sintel h265 test files are fine and even some of the UHD h265 ts files I have are fine also an mp4 remux of a problem file with nightly ffmpeg plays. If someone is interested to take this up I'll make some example files (that don't work anymore) available on my server.

Thanks for any assistance.

I'm building a new living room HTPC, it's mostly out of used workstation parts so it has a 3770K overclocked to 4.2ghz. I'm curious if this'll do 4K HEVC, not that I'm planning on getting a 4K TV, I'd just like to be ready for the possibility of files in that format. Though I'm pretty sure my AMD A8-3870K could never do HEVC 4K without a GPU to do the work for it.

[fritsch]

Just try it - samples are out there. And having a core i7 3770K with 4.2 ghz in the living room is so much overkill ... just to save some gb of very cheap hard disk space.

[meimeiriver]

Crap. No HW decoder supports it, None, zero, nappa. This means back to high powered and noisy boxes for SW decode. No thank you please.

Wouldn't mind if the devs kept an open mind about it. Sure, no one support it yet: how could they?! It's totally new. H265 is a wicked awesome protocol, though, and we can expect it to become as widespread and common as H264 is now.

The larger problem, however, way I see it, is that our current chipsets, like my Intel 4600, don't support H265 yet, of course. So hardware acceleration is going to be absent (on the Broadwell-K chips maybe?). Let alone 4K support.

Best bet will be the next generation 0f nvidia Chipsets.

Hi,

It seems you didn't merge OpenHEVC optimisations. I just tetsed official ffmpeg, OpenHEVC fork and recend Kodi 14/Helix from github. From my tests on 4K DCI/16Mbps hev1, OpenHEVC version is about 10% faster than offcial ffmpeg and kodi 14.

Saying OpenHevc I mean this: https://github.com/OpenHEVC/FFmpeg/ - it's really faster and I think you should look at this. On my i7 3770K official ffmpeg/kodi is about 25-30% cpu load while playing 4k DCI and openhevc only 15-20% so there is big difference.

Of course I didn't say anything about xbmc gotham, since it's tragical, the same movie is 90% cpu load I suspect much older ffmpeg version there.

[Martijn]

then they should send patches to ffmpeg

[giaur]

It's another ffmpeg fork so I wouldn't expect it to be happen.

[fritsch]

Out of interest: How did you build xbmc with openhevc's ffmpeg version?

[fritsch]

And how did you measure those "10 per cent"? if we are at it.

[giaur]

I played the same movie using official ffplay and openhevc version and wathed cpu usage. It was about 10% lower on openhevc, at least on my hardware. Of course it's not really good test but I think it's worth to look at this. Since you have your own ffmpeg fork, you can also look at openhevc optimisations.

As far as I know, it's already used in lav codecs for windows and it also runs very smootch.

[fritsch]

Yeah, if that coder wants his work to be seen upstream, he will send it upstream. ffmpeg does not only consist of hevc but of many, many things more.
