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.

                          stable for me. h264 encoder has been working
                          stable too. mpeg2,h263,mpeg4p2 encoders
                          haven't been tested as much.<br>
                          There are a few known bugs in the IPU
                          transform and eglvivsink transform plugins.
                          The reason why it is still alpha is that some
                          features are missing (second deinterlace mode,
                          some element properties, and 3D support). Once
                          this is done, I'll switch to beta. The planned
                          release of the beta version is end of
                          November.<span><font color="#888888"><br>
