gst-ffmpeg
This module contains a GStreamer plugin for FFmpeg.
PLUG-IN DEPENDENCIES AND LICENSES
---------------------------------
GStreamer is developed under the terms of the LGPL (see LICENSE file for
details). 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.
This is GStreamer gst-libav 1.17.0.1.
The GStreamer team is thrilled to announce a new major feature release in the
stable 1.0 API series of your favourite cross-platform multimedia framework!
As always, this release is again packed with new features, bug fixes and
other improvements.
The 1.16 release series adds new features on top of the 1.14 series and is
part of the API and ABI-stable 1.x release series of the GStreamer multimedia
framework.
Full release notes will one day be found at:
https://gstreamer.freedesktop.org/releases/1.16/
Binaries for Android, iOS, Mac OS X and Windows will usually be provided
shortly after the release.
This module will not be very useful by itself and should be used in conjunction
with other GStreamer modules for a complete multimedia experience.
- gstreamer: provides the core GStreamer libraries and some generic plugins
- gst-plugins-base: a basic set of well-supported plugins and additional
media-specific GStreamer helper libraries for audio,
video, rtsp, rtp, tags, OpenGL, etc.
- gst-plugins-good: a set of well-supported plugins under our preferred
license
- gst-plugins-ugly: a set of well-supported plugins which might pose
problems for distributors
- gst-plugins-bad: a set of plugins of varying quality that have not made
their way into one of core/base/good/ugly yet, for one
reason or another. Many of these are are production quality
elements, but may still be missing documentation or unit
tests; others haven't passed the rigorous quality testing
we expect yet.
- gst-libav: a set of codecs plugins based on the ffmpeg library. This is
where you can find audio and video decoders and encoders
for a wide variety of formats including H.264, AAC, etc.
- gstreamer-vaapi: hardware-accelerated video decoding and encoding using
VA-API on Linux. Primarily for Intel graphics hardware.
- gst-omx: hardware-accelerated video decoding and encoding, primarily for
embedded Linux systems that provide an OpenMax
implementation layer such as the Raspberry Pi.
- gst-rtsp-server: library to serve files or streaming pipelines via RTSP
- gst-editing-services: library an plugins for non-linear editing
