In 1998, Microsoft has developed the first MPEG-4 encoder used on the PC, including MS MPEG4V1, MS MPEG4V2, MS MPEG4v3 series encoded internal code, where V1 and V2 are used to make AVI files, until now it Is the default component of Windows, but the code quality of V1 and V2 is not very good, until the MS MPEG4v3 has achieved improvement, the quality has a significant progress, but I don't know where the Microsoft has a heart, but the MS MPEGV3 video code The kernel is closed, which is applied to Windows Media stream media technologies, that is, in the ASF streaming media file we are familiar with, the ASF file has some advantages, but due to excessive enclosures cannot be edited, the last is widely used, this It is angered those who are not afraid of the video hackers and dedicated to drilling video coding. Later, these groups not only crack Microsoft's video coding, but also through their modifications, a new video coding was born: That is Widely circulated MPEG encoder-DivX3.11.
DivX uses MS's MPEGV3, and it is improved and added to DivX3.11, which is also one of the MPEG-4 encoders that are commonly used on the Internet. Soon, DivX was sent to red, almost the industry's standard, but it always appeared, and DivX's basic technology is illegally stolen Microsoft. Microsoft claims people who have promoted DivX. Enterprises are investigated, but one of the Creators of DivX technology is fully applied to legalize DivX, which is based on DivX, although it is invented by Window, but has not used any Microsoft technology, more set The new company DivxNetworks fully promotes DivX, it seems that the big tide of DivX (commonly known as compressed movies) is unmountable.
However - it seems that any story that attracts eyeballs will change at a critical moment. The development of DivX can't get out of this public case. In the successful development of DivX, DivX's technology is gradually mature, and the business opportunities are unlimited. The original intention of DivXNetworks is to get rid of Microsoft's technology, and thus initiate a fully open source project. The target is "Projet Mayo". The goal is to develop a new, open source MPEG4 encoding software, because it is fully compliant with ISO MPEG Standard, OpenDivxCodec attracted many software, video master participation, soon developed a higher performance encoder ENCORE2, just in DivX's most brilliant period, DXN suddenly closed DivX Source code, and released its own product Divx4 on the basis of Encore2. It turns out that DXN has already left the back door, DivX takes the LGPL protocol, not the GPL protocol, although they are all public license agreements, guarantee freedom And modify the right to software or source, but LGPL allows private, DXN is to use this protocol to make a knife.
Then, like the Hollywood revenge movie, all the software that was smashed by DXN, and the video group took another portal. He gradually re-gathered the development force, and he raised the rich fence. On the foundation of the OpenDIVX version, A new MPEG-4 encoding -XVID, the order of the name and DVIX are just the opposite, just from the name, you can see the power full of revenge.
