FFmpeg是一套可以用来记录、转换数字音频、视频,并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。
可能很多朋友知道,现在市面上很多视频编辑软件、本地播放器、浏览器、甚至是编码格式等等都使用到了FFmpeg。
FFmpeg被许多开源项目采用,比如ffmpeg2theora,VLC, MPlayer, HandBrake, Blender, Google Chrome等。还有DirectShow/VFW的ffdshow(external project)和QuickTime的Perian (external project)也采用了FFmpeg。
也可能有朋友知道FFempeg官方有个叫“耻辱柱(Hall Of Shame)”的东西,FFmpeg官方会将发现的那些不遵守开源协议(LGPL或GPL许可证)的软件或其母公司公诸于世。
由于FFmpeg是在LGPL/GPL协议下发布的(如果使用了其中一些使用GPL协议发布的模块则必须使用GPL协议),任何人都可以自由使用,但必须严格遵守LGPL/GPL协议。有很多播放软件都使用了FFmpeg的代码,但它们并没有遵守LGPL/GPL协议,没有公开任何源代码。我们应该对这种侵权行为表示耻辱。
虽然没有物质上的惩罚,FFmpeg耻辱柱更多的是一种精神层面的降维打击。这东西虽然对于普罗大众来说没什么用处,但是在这里我还是想来做个记录者……
官方正文
Shame page will be offline until entries are updated.
This is a list of projects or companies violating FFmpeg’s license. The list
is part of an effort to get them to comply with the licensing terms by shaming
them in public.
A good way to help us is to link to this page, thereby boosting its
pagerank, possibly near or past the homepage of the offender. We discourage
you from using or buying the software listed here, unless you do so to pester
its producers and demand that they comply with the license of FFmpeg.
Our issue tracker also contains a list of
license violations.
If you become aware of license infringements, please notify us on the
ffmpeg-devel mailing list and/or add
it to our
issue tracker.
