Problems building gstreamer-plugins-base v1.14 with yocto

[Norbert Wesp]

Hi everybody,

this week I had a problem to build our image with gstreamer.

Since we use 'meta-gstreamer1.0' instead of our layer, the installed
version of gstreamer changed from v1.12 to v1.14. Within gstreamer v1.14
gbm is supported by gstreamer1.0-plugins-base_1.14 and will break our
build process. Furthermore I get an error because
'EGL_PLATFORM_GBM_MESA' is undefined in
'gst-libs/gst/gl/egl/gstgldisplay_egl.c'.
Note:    This only effect builds with an am335x processor. All builds
with an imx6 does build successfully.

Here is a little snipped of the output, I get from yocto:
| In file included from
../../../../../gst-plugins-base-1.14.1/gst-libs/gst/gl/egl/gstglcontext_egl.c:55:0:

fatal error: gbm.h: No such file or directory
|  #include <gbm.h>
|           ^~~~~~~
| compilation terminated.

Here is what I changed:

changes:
    #ifndef EGL_PLATFORM_WAYLAND
    #define EGL_PLATFORM_WAYLAND 0x31D8

With this changes I was able to build a complete image without WARNINGs
or ERRORs.

So my questions are:
1. Did I found a bug or is there some issue in our configuration?
2. Is way I fixed this issue okay, or should I do it another way?

Thanks and greez

At first sight, this change looks correct. Would you mind creating a
bugzilla issue and attaching your "git format-path" patch so someone
could code review and test ?
