I don't know... you would have to try it. We test UHDcode against a wide range of spec-compliant HEVC bitstreams, but as far as I know, it is also designed to decode any bitstream regardless of whether it fits a legal profile (we don't ask questions, we just decode). Of course, our main objective is to make sure that any possible legal bitstream can be decoded quickly and accurately. We look forward to your feedback.

Building x265 with GCC now supports STATIC_LINK_CRT to include minimal Windows GUI API support, as yet linked from the basic MSVCRT.DLL; would you rate this option useful / important / irrelevant? This DLL will probably be present in quite any Windows version, I believe; linking it statically may not be as important as when someone would compile using MS Visual Studio, but rather add redundant code to the distributed binaries, I guess?

I did not yet try this software, instead I (personally) will try to rely on freeware in the future too; but for these users who prefer it simple and specific, it is a limited time offer to "purchase" it with a 100% discount, you will only have to register to obtain a bundle of an "MP4 to HEVC"* converter plus a DirectShow HEVC decoder.
*I guess the result will be HEVC video + supported audio again in an MP4 container. But I have seen a modified x265 including L-SMASH as MP4 multiplexer already. And I can multiplex raw HEVC into MP4 later too, with MP4Box or L-SMASH. If you can handle our known-good free converters (like MeGUI, Hybrid, StaxRip), you may have little need for "x265 HEVC Update". |

Since there is no UHDcode plugin HEVC decoder thread yet, I have evaluated the decoder in my thread.
For anyone interested it's here: http://forum.doom9.org/showthread.ph...68#post1715668

Enabling the STATIC_LINK_CRT cmake option does not (yet) generate a Windows executable with statically linked CRT. I believe it is just "prepared support" for when it will be implemented...

If it works you can patch cmake updating one file from cmake-mod.7z -- it removes default -O3 optimize option which is added at the end of compiler options and unable to specify any option below -O3. Last edited by Ma; 1st April 2015 at 16:32. |

So partially crippled decoder, a limited x.265 GUI, an installer that messes with file association requires activation and God knows what else, and a cart system that is iffy and requires email registration. Also little information for where this is going.

As you know, most consumers only have 8 bit capable graphics chips/drivers, and displays. True 10 bit capable systems tend to be rather expensive and uncommon. UHDcode automatically accelerates on AMD OpenCL capable graphics (latest generation), including both APUs and discrete GPUs. We're working to extend this acceleration to Intel and NVIDIA graphics. I'm not sure why we didn't fare so well in a head to head with LAV, but I suspect that the problem is in the DirectShow communication. Our DShow filter decodes frames and gets them ready for the player, which requests them as needed. It wasn't built for benchmarking (decode as fast as you can... don't wait for the player). I'm just speculating... I'll definitely check into this. We'll be happy to address any concerns about how the x265 HEVC upgrade sets file associations. I'll take this up with our dev team. What limitations are you referring to in the x265 Encoder UI? Our cart system doesn't require email registration (it doesn't make you confirm your email address before it lets you get the product). You can put a fake email address in, and still get the product. However, you won't be able to log into the cart later to see your order or retrieve your key if you use a fake email address. Our license activation server suffered some hiccups yesterday, and our team has taken care of it. We'll keep an eye on this. In the meantime, if anyone had a problem, PM me the email you used when you checked out, and I can check into it. I can send you another key if needed. I think we've been fairly open about what this is, and isn't, and I'm happy to shed more light on where it's going. It's a useful ready-to-use implementation of our HEVC libraries. We're not heading down a path of competing with companies that build complete video encoding systems (our customers). We simply wanted to make x265 and UHDcode more accessible to the average person. If you're a power user who is already happy with our command-line interface, or one of the many applications that incorporates x265, this is probably not for you. |

Please don't say that you never tested your "fastest in the world" claim against the most popular decoder, this is just silly. |

it doesn't matter if you don't have a 10 bit display. it is well know that encoding in 10 bit is more efficient and a common practice these days. even the nvidia 960 GTX can do ASIC 10 bit HEVC and of cause it can even public broadcast is 10 bit.
BTW. nearly all directx 10 GPUs can output 10 bit or more using DP/HDMI by using a directx fullscreen surface. |
