[Gary Bisson <bisson.gary@gmail.com>]

Open-source GStreamer 1.0 plugins for i.MX6 platforms.
More info at https://github.com/Freescale/gstreamer-imx

Signed-off-by: Gary Bisson <bisson.gary@gmail.com>

Modifications v2->v3:
- Change package name from gst1-plugins-imx to gst1-imx
- Remove commands unnecessary parentheses
- Modify package comment to clarify it is only working on i.MX6

Modifications v1->v2:
- Use of github helper macro
- Modify package comment with Peter S. original patch
- Add comment for eglibc dependency (due to GPU libs)
- Remove comments on package dependencies

This patch has been tested using an i.MX6Q SabreLite (nitrogen6x config) along
with the usual Tears of Steel movie in 1080p:
http://media.xiph.org/mango/tears_of_steel_1080p.webm

Below are the commands used to test the different sinks:

$ gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxipusink
$ gst-launch-1.0 filesrc location=/root/tears_of_steel_1080p.webm ! \
matroskademux ! imxvpudec ! imxeglvivsink

The toolchain used was the Sourcery CodeBench 2014.05. The video above also
requires the following extra configuration in order to demux the content:
BR2_PACKAGE_GST1_PLUGINS_GOOD=y
BR2_PACKAGE_GST1_PLUGINS_GOOD_PLUGIN_MATROSKA=y

Thanks,
Gary

+	  This is a set of GStreamer 1.0 plugins for plugins for Freescale's
+	  i.MX6 platforms, with emphasis on video en/decoding using the VPU
+	  engine.
+
+	  This software supports only the i.MX6 SoC family and requires a
+	  kernel that includes the i.MX6 specific headers to be built.
+
+	  The software as a whole is currently in beta stage.
