[meta-freescale] Regarding GStreamer-1.x status on iMX6Q

[Carlos Rafael Giani]

You'll want to add gstreamer1.0-plugins-base-meta and 
gstreamer1.0-plugins-good-meta . Note the difference between packages 
and recipes in OE.

As for building gstreamer-imx , you first set up these environment 
variables:
* CC
* CFLAGS
* LDFLAGS
* PKG_CONFIG_PATH
* PKG_CONFIG_SYSROOT_DIR
* PATH

then, you call ./waf configure --kernel-headers=<path to kernel 
headers>  build . This produces binaries in a newly created build/ folder.

Here is a script I've made for myself (building for a Sabre SD here):

export ROOT="/path/to/my/OE/dir"
export CFLAGS="--sysroot=${ROOT}/tmp/sysroots/imx6dlsabresd"
export LDFLAGS="--sysroot=${ROOT}/tmp/sysroots/imx6dlsabresd"
export 
CC="${ROOT}/tmp/sysroots/x86_64-linux/usr/bin/cortexa9-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc"
export 
PKG_CONFIG_PATH="${ROOT}/tmp/sysroots/imx6dlsabresd/usr/lib/pkgconfig"
export PKG_CONFIG_SYSROOT_DIR="${ROOT}/tmp/sysroots/imx6dlsabresd"
export PATH="${ROOT}/tmp/sysroots/x86_64-linux/usr/bin:${PATH}"
./waf configure 
--kernel-headers=${ROOT}/tmp/sysroots/imx6dlsabresd/usr/src/kernel/include/ 
build

The produced binaries are:
build/src/eglvivsink/libgsteglvivsink.so
build/src/ipu/libgstimxipu.so
build/src/vpu/libgstimxvpu.so
build/src/common/libgstimxcommon.so

Copy libgstimxcommon.so to your device's /usr/lib/ directory. The other 
three go to /usr/lib/gstreamer-1.0 .
Note that you need the GLES/EGL headers from Vivante to build the 
eglvivsink . The IPU plugin needs kernel headers (an unfortunate 
necessity). The VPU needs libfslvpuwrap .

I will add an OE recipe for this soon. It would make things a lot easier.
