...include the support for 8K video. The current Snapdragon 845 mobile platform supports up to 4K video playback, which lacks the support for my requirement. So I choose Android-x86 as my platform for development, which is Android OS runs on Intel x86 architecture. I've tried to play 8K(7680*3840) HEVC encoded video on Android-x86 7.1-r2 with VLC for Android, the screen freeze. My CPU is Intel Core i5-7400 and my graphics card is NVIDIA GeForce GTX 1060. I am pretty sure my NVIDIA card is able to decode 8K video. Because with the same hardware, I play the same 8K video on Ubuntu 16.04 with ffplay...

But I know a driver for my NVIDIA card is a must for the hardware decoder to work. Can somebody shed some lights that if I want to play an 8K HEVC encoded video on Android-x86 with NVIDIA's decoder enabled, what should I do in this project? And how to start? The steps are straightforward, although each one of them is fairly tricky. 1. Load decoding firmware into the engine 2. Hook up engine "servicing" (like interrupts, channe...

Hello, I don't have worked on the NHW Project this past week (I also have to work on an other project) but I found time today to make an "extensive" testing of x265 (HEVC) and the NHW codec at high compression (-l7 setting). That's right that x265 is a very good codec! Really impressive.The NHW Project is not as good, it can only compete with x265 (HEVC) on quite high quality images, with hardly no blurred areas and JPEG artifacts. It's a pity the real mes...

Hello, I don't have advanced on the NHW Project this past month, but I have definitely validated its characteristics and this new version. The NHW Codec preserves or enhances image neatness and sharpness, which translates that on good quality images the NHW Codec is globally better than HEVC, and on degraded (with blur, artifacts) images it is worse than HEVC because it lacks of precision. I have made tests on 100 images from the Internet. The NHW Project still lacks very high compression, and I think now I will inspire from HEVC, that is to say, I would like to strongly remove detail...

Hello, I have improved quality for -l4 and -l5 high compression settings.These settings are now really better and very competitive, I now prefer them compared to x265 (HEVC). Update at: http://nhwcodec.blogspot.com/ I am also working on -l6 quality setting, I can simply increase quantization for it but I am not totally satisfied with this solution for now... Looking for more advanced processing at these compression ratios, like an efficient denoising, as do HEVC, AO...

...it (I put on pause the NHW Project from August 2013 to February 2018 )... And I realize that very high compression is quite difficult because all the noticeable artifacts appear there... With this update, my new -l13 very high compression quality setting is really better, and can compete with x265 (HEVC) on rather good quality images, because it has more neatness, but that's right that on "degraded" images (compressed, with artifacts), HEVC starts to excel and be very impressive. I find that -l13 very high compression setting is the limit where the other codecs (WebP, x264, Rududu,....

...n high contrast and give it to low contrast.I think in a first time, I will only use residual coding for the low contrast area errors.I will try to do this next month if I can find time, and will let you know what it gives. I am also aware that with all this, it will be very very difficult to beat HEVC, VP9/10, Daala.The entropy coding is certainly the most interesting part of my codec.

...s, the entropy coding schemes are less efficient, and so we could save for -l8 setting nearly 2KB per compressed .nhw file in average, will have to improve them... This new -l8 setting has so a good neatness to the detriment of details.It is still experimental, but I find it competitive with x265 (HEVC). Update at: http://nhwcodec.blogspot.com/ Any feedback is very welcome! Cheers, Raphael -------------- next part -------------- An HTML attachment was scrubbed...

...age to let you know that I get back to NHW Project currently. I downloaded 20 images from the Internet with rather good quality (mainly faces), I compressed them at high compression -l7 setting with the NHW Project, and on 19 images out of 20, I visually prefer the results of NHW compared to x265 (HEVC)!!! -I can make available these 20x3=60 512x512 24bit bitmap images for those who want, just let me know.- I did not select these 20 images, it was the 20 first rather good quality images that Google Images gave me (I entered the name of an actress...). So I am quite satisfied with these results,...

...will not disappear as many great projects before like Rududu codec, DLI compression, UCI codec (x264 intra) and others... -but these projects will maybe resurrect today-. There are some delay with the -l6 and lower quality settings because it is difficult to create good ones, that can compete with HEVC.But it would be so great to have some help from the community! Because I think that the NHW Project is not dead, and I start to be more optimistic with the recent improvements, because from -h3 to -l5 quality settings, it is very competitive, I find it on par or better than x265 (HEVC)! And it is f...

Hello, Could some of you take a look at the image comparison between the NHW Project and x265 (HEVC) at high compression, available here: http://nhwcodec.blogspot.com/ . I would be very very interested in your opinion, and it would help me to perfect the NHW Project.For me the NHW Project has more neatness, and x265 has more precision. Else, I was a little lazy these past months, as I didn'...

Hello, If it could be of interest, here are new speed measurement for -l13 very high compression setting. For x265 (HEVC), I use BPG codec, and this time I use -m 0 setting which uses the fastest encoding setting of x265.I run the .exe 10x times and I pick the best scores. So here are the timings at -l13 very high compression: Encode time: x265 (BPG -m 0): 80ms NHW: 20ms Decode time: x265 (BPG): 90ms NHW: 10ms S...

Hello, Just a quick message to let you know that I have made good quality improvements for very high and extreme compression of the NHW Project (-l8 to -l15 quality settings).The NHW Project starts to be really competitive with x265 (HEVC) at these very high compression ratios.I even find the NHW Project visually better than x265 (HEVC) for mid and high compression! I have also improved encoding speed (C optimizations). More at: http://nhwcodec.blogspot.com/ We can still save 2.5KB per .nhw compressed files. I wanted to correct...

Hello, I have just added a new -l18 "extreme" compression quality setting to the NHW Project.I find this quality setting very good and actually better than x265 (HEVC). First, I wanted to let you know that compression of the wavelet DC image is really not efficient at extreme compression, I have the fast ideas to improve it, and so we can really save 2.5KB per .nhw compressed files in average at extreme compression (this is confirmed by recompressing the .nhw f...

Hello, These last 2 months I have been in contact with a very impressive and friendly engineer from Intel who has written an article on my codec and the 4-5 new codecs in general that competes with HEVC.He finally answered me that as Intel is a founding member of the Alliance for Open Media and chairs several MPEG WG around HEVC, they won't be able to put extra resources on the NHW Project.So far nothing surprising, Xiph.org was also not interested in the NHW Project, but the good news is that...
