Questions tagged [gstreamer]

Questions related to GStreamer (also known as Gst), an open source multimedia framework, powering everything from linux servers and linux desktop systems to a host of embedded devices.

GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing. Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.

GStreamer has been ported to a wide range of operating systems, processors and compilers. These include but are not limited to Linux on x86, PPC and ARM using GCC. Solaris on x86 and SPARC using both GCC and Forte, MacOSX, Microsoft Windows using MS Visual Developer, IBM OS/400 and Symbian OS.

The up-to-date documentation for Gstreamer can be found here. Old documentation for the 0.10 versions of GStreamer can be found here.

Some basic tutorials can be found here.
