A free lossless compression codec "ZeroCodec" created by Japanese



Ultra high-speed remote desktop software specialized for "game" "movie" "music"ZeroRemote"Ichi Geki, who is the author of ZeroRemote, developed it with the aim of" aiming for speed improvement using video compression codecs "instead of pursuing their own speed in terms of high speed when using ZeroRemote, as a result of this development It is said to be "ZeroCodec" which is a free video compression codec. It is said that input / output correspondence format is "RGB" "UYVY" "YUY 2", and in case of RGB it is "lossless compression with zero degradation of image".

Since it is said that "individual corporate nonprofit is free regardless of nonprofit", it may be interesting depending on future development situation.

Details are as below.
Download of the main body is possible from the following.

Unzip the downloaded ZIP file, right click on "zerocodec.inf" in it and click "Install" and it is completed. When uninstalling it is possible from "Add / Remove Programs", so it's kind design that you can try easily.


"ZeroCodec" is displayed as a codec for compression like this. There is nothing that seems to be particularly configurable at the present time.


Development seems to be promoted with emphasis on image quality, transfer rate, etc. The appearance of trial and error is written on the blog below.

Rather than pursuing speed with ZeroRemote, it is a Yu system that improves speed by using video compression codec. Well, AMV 3 is a method that I was concerned about quite a lot since it became rapidly fast.

Respect and Yuka homage to AMV 3 and Yuka is such feeling ('д `)

It is already uncompressed and a prototype with no difference is made, but if the resolution is 1280 x 1024 and it is the highest load15 FPS or moreI'm transferring it! This is Odoroki! So far at ZeroRemote somehow it was about 9FPS!

However, although the transfer data size is 80 MByte / sec or so, it is www

It is surprising that transfer is possible even with this data size. Well, as it is still in the development stage, I can not see anything as to whether the speed drops or increases as a result of compression processing etc. Do you feel like trial and error over time? From now on I'm going to implement various functions (compression / difference etc) and "ZeroCodec (tentative)", but conversely ZeroRemote is trying to reduce the function. It is a direction to reduce the screen transfer processing method considerably and to ask the video compression codec to do its best instead.

The name is "ZeroCodec", of course, free software. FourCC is "ZECO". Operation confirmation by OS is Windows XP. Versions are not beta version forever "v1.0.0". If you input and output in RGB,Zero deterioration of image by lossless compression.Performance,Compression rate "subtle", speed "subtle", total "subtle"is. Three input / output correspondence formats are "RGB" "UYVY" "YUY 2". Difference processing is super-omission, so it is very weak against reverse playback. Structurally, it internally converts it to RGB 24 bits, performs differential processing, and compresses it. By the way there is no setting screen or anything. I can not see the program source, but I think it is very short. It is partly assembled. Since it seems that you can not use the video compression codec unless you install it, we plan to install it with "inf" file and uninstall it with "fix / delete program". In addition, it is probably a premonition of full loading of bugs .... In rabbit, I made an early attempt and stuck to Yu.

Codec completed in real 7 days! ('Д `) ノ

In addition, Mr. Ichi Geki who is the author is told the bride "You, do not have to pay for it?", But ignored it. The person himself said, "If it makes a fee, something is here, 'strict' ... ('д`) ", it is said that we will continue to make improvements to improve the compression rate and speed I will.
