Build a gstreamer application with yocto for imx6 Wandboard

Build a gstreamer application with yocto for imx6 Wandboard

[-- Attachment #1: Type: text/plain, Size: 603 bytes --]

I am using the "master" branch of Yocto.  I have a gstreamer application
that is compiled and tested on Ubuntu.  I have a Makefile for this
application.  The Yocto build I use fsl-image-test and added a few plugins
in my conf.local.  I have tested all the plugins/pipeline that is needed
for this app with gst-launch.

I just want to run a quick test of the code on the wandboard,  what is the
fastest way to do a make and produce a executable ?  I looked at the Yocto
manual and it seems that it calls for creating a recipe etc.  Is there a
simple template that I can use?

Thanks,
Norman

You can try to use your already built binary into any rootfs.

If you decide to try to make the recipe, you can share here your 
problems, but, please take care of proprietary stuff.

You can try at first an tiny example:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/recipes-multimedia/libfslvpuwrap/libfslvpuwrap_1.0.40.bb?h=master-next&id=9135a32b50800cac2c3feb0bac1f19c3d6743add


and then go to a more complex one:

http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/recipes-multimedia/gst-plugins/gst-fsl-plugin_3.0.9.bb?h=master-next&id=9135a32b50800cac2c3feb0bac1f19c3d6743add

Daiane,

Thanks for sending my the examples, I am sorry that I am not grasping the
examples.

Looking at the "tiny example" below, it inherits autotools, so that is
good, as I am using autools in my project to generate Makefile as well.

My questions:
- Where in this recipe below points to my project directory?
- Is ${FSL_MIRROR}/${PN} where I place my project?  Or
- where in the build/tmp/work/... area should I place my project? In my
case, what environment variables shall I use?

How can I skip the SRC_URI checksums?  I don't need that as I am placing
trusted source in the the tree.

Would BB automatically run ./configure , make and make install ?

How would this recipe get called ? entry in my conf.local?

Many Thanks,

Norman

The "source" of your package is on SRC_URI variable. you may point a git 
uri, or a mirror to you tarball.

you can have SRC_URI = "file://tarball.tar.gz" if you want

it depends on how you make your recipe PACKAGE_ARCH = "${MACHINE_ARCH}" 
says it's a package that only work for that machine, so it will be 
placed on tmp/work/machine_name. But, a lot of packages are commom for 
any architecture, for example ssh.

hum, you cannot. Please, use the checksums :D <3

(imagine that you know the source is trusted, but yocto need to 
"download" and "unpack" it, so you added 2 steps of "untrusted" behavior.)

yes, but only if you inherit autotools

bitbake mysweetheartpackage when you're developing should be enough.

If you want it installed on your image, you add it on your image install.

easiest/dirty way is local.conf CORE_IMAGE_EXTRA_INSTALL.
