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.

If you have some time today, could you answer one last question?
*How* do I include 1.x into my build? I switched repos from Dora to
Master and added these packages:
gstreamer1.0
gstreamer1.0-plugins-base
gstreamer1.0-plugins-good
I am able to confirm that all three have been added to my project, but
gst-inspect-1.0 only shows me gst-core has actually been installed.
Plus I don't think this includes anything from the gstreamer-imx
repo. If you could give some basic instructions I would greatly
appreciate it.
Thank you,

Yes, the current status in Github is what I was talking about. The
only thing missing from the decoder atm is VC1/WMV3 support. I
have to figure out some parsing details there.
My current focus is on the video transform element (bugfixes &
second deinterlace mode).
I forgot to mention one other thing that already works:
transcoding with zerocopy. Meaning, pictures decoded by the VPU
can be passed to the encoder directly without having to copy the
pixels. Initial tests show that real-time 1080p transcoding to
h264 baseline is feasible with this.

That's great news! At this point in time decoding is the only
thing important to me. Have you pushed the stable version of the
decoder to the gstreamer-imx repo?
Thanks,

Can anyone give a status update on the
stability/functionality of
gstreamer-1.x plugin on the imx6Q? The readme page
has listed it in
alpha for a while.
For the application that I am working on, it would be
more beneficial
to use 1.x. If their is still work to be done with
porting it over, I
would be available to help as long as someone points
me in the right
direction.
Carlos did the current public work for 1.0 support. He
may provided a
good status update on this.
I prefer this email address :)
Current status: decoder has been running stable for me. h264
encoder has been working stable too. mpeg2,h263,mpeg4p2
encoders haven't been tested as much.
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.
