Strongene PC OpenCL HEVC/H.265 Decoder (AMD)

So, recently I poke around the internet searching for information regarding dxva HEVC.

I only found 2 information ; Intel Haswell HEVC dxva with beta driver and AMD HSA/Opencl assisted decoding?

I am planning to upgrade my HTPC, (very old pentium dual core E2160 with ATI HD4350, PSU exploded and took away everything with it).

Of course, Intel haswell offering kinda expensive compared to AMD richland (yeah, a8-7600 kaveri still missing in action, have to make do with what available). So, I need to future proof against the computational extensive hevc.

Thus, anyone with amd richland apu can visit this site http://xhevc.com/en/downloads/downloadCenter.jsp and download plus install Strongene PC OpenCL HEVC/H.265 Decoder and report back the CPU + GPU utilization (windows task manager + gpuz screenshot?) after running it with a 4K hevc video from http://www.elecard.com/en/download/videos.html ?

According to release note (copy paste time) :
1. This version is an accelerated version powered by heterogeneous computing technology and written by OpenCL. The OpenCL version is developed jointly by Strongene and AMD;

2. This version is only for the individual test of HEVC decoding;

3. Compatible with the reference software HM12.0; 4. The OpenCL Version automatically detects the hardware capability to enable OpenCL acceleration. This version supports the OpenCL devices like AMD HD 5000 and above discrete GPUs, and AMD APUs (like Richland and Kaveri).

Those with ATI/AMD HD 5000 and above might wanna test it as well......

Lentoid source / decoder does not work with Elecard clips (.ts or demuxed to .hevc) somehow. Black screen, can't play with Kaveri 7850K.

In that case, then it is better for me to get the 'haswell refresh' CPU since intel plan to support some form of dxva with the IGP's execution units. Last I read at intel forum, minimum requirement for IGP is HD Graphic 4400 and above.

renethx, thanks for the testing, I really appreaciate it. I am going to get Core I3-4150 next. (strange, can't seem to find the low power 'T' variant of this model around the net with reasonable price, oh well)

You can add Nvidia cards with Kepler and Maxwell architecture, using latest beta 340 family drivers.

Thanks for the recommendation. Maybe in future when 8K contents becomes a norm.
I bought an used I3-4330 instead since its price was within my budget limit.
DXVA Checker indicates support for HEVC VLD Main, unfortunately, there isn't any decoder that support HEVC DXVA yet. Not that I known of (Currently lavfilter doesn't support HEVC DXVA decoding).

So, I can't test Intel implementation of hardware assisted decoding.

Actually I don't recommend anything, I'm just telling you that you can add Nvidia to the other two brands supporting HW assisted HEVC decoding.

So all big three, support one way or another HW assisted HEVC decoding.

The problem is - as you 've already mentioned - there are no decoders to test the implementations in real world and not in theory.

Using my old Core2Duo and HD 5750 card, it works for most of my H.265 samples, but with no clear performance benefits over the CPU only decoding.

My platform is very old supporting PCI-E v1.1x4, so maybe that's the problem.(it needs PCI-E v2.0)


I will try with Nvidia/Intel cards to see if it's compatible (the site is not clear about that)

Guys quick question that is confusing the heck.265 out of me...

I understand the following :
2013 4k tv's did not have the HEVC (H.265) decoding, so we cannot watch Netflix or amazon prime yet, before buying a decoder.
2014 4k tv's have a HEVC (H.265) decoding unit built in.

What about computers with a 4k monitor?

I have a dual titan set up, i7 quad...do I need a HEVC (H.265) decoder? Or will the PC play 4k content?

Thanks
quo

Doesn't adobe premiere pro convert most of these formats?
I do not understand Elecard's website.
Why would we need their software?

The PC always decodes HEVC or other video formats.

What we are talking about here is which component exactly will decode HEVC video.

Is it CPU, GPU or a specific ASIC inside GPU.

With your system, use a video player app like MPC-HC or PotPlayer and you will be fine .
