xvid是个本来不会出现的东西,就是divx倒过来写.
当初Gaj之流的几个家伙搞opendivx的时候,一开始是很像模像样的像一个open source
的,free的项目,当初有很多人吸引过去一起开发,测试.
后来那几个家伙一夜之间露出骗子的本来面目了,把opendivx的成果一股脑带走,变成了
封闭源码的divx4,而后进一步变成现在的收费的divx5了.opendivx也就同时死了.
当时这事让开放源码界/divx爱好者大跌眼镜,也非常恼火,因为他们的努力测试和编码
变成了人家的钱袋.可以想知当时受骗的人中不乏divx group的成员,这就可以理解为什
么divx scene为什么要ban divx4/5的原因(divx4/5实际上在技术上肯定比divx3.11好),
因为受骗,而不仅仅是商业软件的原因,同样是商业封闭格式的rar就在warez中用的很好
(而zip是开放格式).
后来就有几个人拿了opendivx的最后还开放源码的版本回去改了改,就是最初的Xvid,现在
改进已经很多了,是大概可以和divx5相比的程度了.

: The federation of releasing groups presents
: The DivX Releasing Standards 2002
: Requirements: Notepad with terminal font or other ascii viewer
: [ INTRO ]
: In an unparalleled event of co-operation and innovation, the DivX scene
: united once again to bring you the 2002 installment of the TDX guideli-
: nes. We thank all of you who so kindly gave up time and energy to bring
: us suggestions and help us brainstorm on the newest of video technolo-
: gies. So without further ado, we present to you, the DivX ripper/enthu-
: siast, the TDX 2002 Releasing Standards.
: [ RELEASE RULES ]
: Movie Length:
: - PAL (25 fps) = min runtime is 105 minutes/CD
: - FILM (23.976 fps) = min runtime is 110 minutes/CD
: - NTSC (29.97 fps) = min runtime is 92 minutes/CD
: TV-Series Episodes shall NOT be exempt from these rules (See Series
: Notes).
: These runtimes are scalable via the following equation:
: N cd time minimum = (N-1) * allowed_time where N is number of CDs and
: allowable time applies to your format
: (i.e. 4 cd FILM rip min = 110 x (4-1) = 330 minutes)
: Media usage is at Ripper's discretion, please use it.
: Releases should utilize at minimum 97% of total media capacity, however
: an undersized release is not a technical flaw.
: AUDIO:
: - MUST be MP3 or Studio AC3 (AC3 transcoding forbidden).
: - MUST be STEREO for STEREO sources, MONO for MONO sources
: (MONO audio as STEREO on source is considered a MONO source).
: - MUST BE VBR! NO CBR MP3!
: - VBR techniques:
: - strongly recommended to use --r3mix with LAME
: - ABR is considered a VBR technique.
: - AC3 MUST be used wisely and correctly.
: - AC3 MUST be interleaved at 64 or 96 ms.
: VIDEO:
: Keyframe:
: - MUST be <=20 seconds and MUST be inserted according to scene
: changes and framesizes as determined by the codec or encoding
: application.
: Framerate:
: - MUST be as close to original source framerate as possible.
: Codec:
