Some of our plug-ins however rely on libraries which are available +under other licenses. This means that if you are distributing an application +which has a non-GPL compatible license (for instance a closed-source +application) with GStreamer, you have to make sure not to distribute GPL-linked +plug-ins. +When using GPL-linked plug-ins, GStreamer is for all practical reasons +under the GPL itself. +HISTORY +------- +The fundamental design comes from the video pipeline at Oregon Graduate +Institute, as well as some ideas from DirectMedia. It's based on plug-ins that +will provide the various codec and other functionality. The interface +hopefully is generic enough for various companies (ahem, Apple) to release +binary codecs for Linux, until such time as they get a clue and release the +source. |
