I want to build a website where user can listen my voice. I want to use only Icecast. But on my website I want to display some data too inside a stream. What data I want to add ? basically on my website there are various images. each image having a number. While I deliver my lecture I want to send image number too. Now I can send this number using http PUSH/PULL but I do not know How it will be

Hello, I am slowly working on the NHW codec. I have re-tested the post-processing function in the NHW decoder that was supposed to remove aliasing but that doesn't work at all, and after several tests I still find this post-processing useful.I find that it gives some good results, rebalances the image (but it is very slight).I know that this kind of post-processing must be taken very

Hello, Just a quick note, some people told me in the past that I must adapt NHW to any image size else nobody will consider and use it.That's certainly right, but again I am working on NHW on my spare time and this task is too exhausting for me.Also, I feel now that it is useless, as I have read that in the very next months, the great AVIF and JPEG XL will be definitely adopted everywhere on

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

Hello, No advance for now on the NHW codec, I am still working on a new quantization scheme to scale down the compression ratios but without luck... Any advice, idea is very welcome.I will also have to correctly code the wavelet filerbank and process on rows and columns and suppress the image transposition (this is for long overdue)... will win few cycles... there are other parts to speed up (in

Hello, I've found some time to get back to the NHW Project.In fact a Xiph forum member told me that even if I will start a new job, he hopes that I will still continue to develop a little the NHW Project, on my spare time.I told him that I would furthermore spend my spare time on the NHW Project if a community around the project could emerge... and he told me that certainly the best way for

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

Hello, Ok that's right HEVC and AOM AV1 are better than the NHW codec, even at mid compression.I only tested my codec with quite neat images, hence the good results, but on more blurred, more compressed images, HEVC and AOM AV1 are definitely better, they are also exceptionnal at high compression. So, yes that's right, the NHW codec has very little chance to penetrate the market, it is

Hello, I don't have advanced (and worked) on the NHW codec recently.I however compiled the codec with gcc -O3 setting (the binaries are available from my demo page: http://nhwcodec.blogspot.com ) and just with this optimization (no mmx, sse, avx instructions,... ) the NHW codec is 6x faster to encode and 4x faster to decode than WebP.As I state that my codec is royalty-free, fast with more

Hello, For those interested, I have added a -l8 "very high compression" setting to the NHW Project. I have added an experimental processing to remove details and preserve neatness.I have also now a fast estimation of entropy of wavelet coefficients and I use it accordingly to the image complexity but it is a very first version... With these new processings, the entropy coding schemes

Hello, I was testing quickly some other lower quality settings -l3, -l4 because high compression is what really lacks to the NHW codec. In fact I can remove -5Ko of residual coding on Y,U,V comps for -l3 and I can remove -10Ko always of residual coding for -l4, and -l3, -l4 settings will be really better than the current ones implemented. I can also increase the wavelet coefficients threshold

Hello, The -l8 "very high compression" setting I posted was not really good.Now I have corrected and improved it, and now the -l8 quality setting is really better, more precision and more neatness. I think now it is a good setting, and I have started to compare it with x265 and it can be now competitive. More at: http://nhwcodec.blogspot.com/ Do not hesitate to test it and give me

Hi all there. I am trying to set up an icecast2 server (wich is already running) to send some stream mount point to another server. I mean, my server is streaming at /radio1.mp3 mount point. We can listen it at http://myserver:8000/radio1.mp3; so, i want to know if is there any way to "clone" that strem and send it to another server, such as http://giss.tv:8000/radio1.mp3 I have been

Hello, I am very slowly working on the NHW Project.I recently made a speed comparison with x265 and wanted to share it with you. On my processor Intel Core i5-6400, in average the NHW encoder (totally unoptimized) is x10 times faster to encode than x265 (png decoding time removed), in average 30ms vs 300ms for a 512x512 24bit color image, and in average the NHW decoder (totally unoptimized) is

Hello, I have just tested to compress the .nhw compressed files with paq8px_v167! And paq8px_v167 is a great compressor!!! I thought we could save 1.5KB-2KB in average per .nhw compressed file, and in fact with paq8px_v167, we can save 2.3KB-2.4KB in average!!! On a .nhw file that is 15KB at -l9 very high compression quality setting, 2.4KB saving represents 16% less space! Great! So now if you

Hello, So thanks to helpful forum feedbacks, I know now that I have to create a website for the NHW Project, make demo pages of the technology, and all that with good visual design.It won't be such easy for me... For example, I can easily supply a description, explanation of the different steps of the algorithm, I can supply images encoded at mid-compression with NHW, x265, WebP, JPEG,...

Hello, Again I thank very much the Xiph forum members for their help and consideration for the NHW Project, really.I also realize I was a little unfair with Monty as just saying that Xiph.org can totally give some web space to document and advertise the NHW Project is already a very big help, it gives credit to the project,...! But the reality is that the NHW Project is a nearly dead project...
