Overview
========
GStreamer-MediaSDK is GStreamer plugins for Intel(R) Media SDK that takes advantage of Intel(R) Media SDK API
to execute video decode, video encode and video post-processing.
License
========
GStreamer-MediaSDK is distributed under BSD-3 Clause license.
See LICENSE and NOTICE files in the root folder for details.
Prerequisites
=============
- Media SDK 1.* or higher
- GStreamer 1.x
Operating System | Packages | Requirement | Notes

| gstreamer1-plugins-bad | Optional | videoparse, glimagesink, etc
Install packages with:
- CentOS 7.1+ with 'sudo yum install <package>'
Building & Installation
=======================
Build and install using usual autotools approach:
./autogen.sh
make
sudo make install
Media SDK package is expected to be found in the directory pointed to by MFX_HOME
environment variable. You can use it as:
MFX_HOME=/path/to/mediasdk ./autogen.sh
or
MFX_HOME=/path/to/mediasdk ./configure
