In order to support the symbol g_enum_to_string in various
project using GStreamer ( gst-validate etc.), the glib minimum
version should be 2.56.0.
Remove compat code as glib requirement
is now > 2.56
Version used by Ubuntu 18.04 LTS
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-omx/-/merge_requests/74>
Modified to use gstglmemoryegl to avoid texture creation/copy operations
at the glupload.
[Matthew Waters]: gst-indent the sources and port testegl to GstGLMemoryEGL
https://bugzilla.gnome.org/show_bug.cgi?id=760918
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.
And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

- append a glfilter just before fakesink
So that we get gltexture or eglimages
- propagate our EGLDisplay to the pipeline
see GST_QUERY_CONTEXT
- share our EGLContext with the iternal gl context
of the pipeline, see GST_QUERY_ALLOCATION
- use GstVideoGLTextureUploadMeta to upload
the incoming gltexture or eglimage to our gl texture
TODO: convert from GLESv1 to GLESv2
See https://bugzilla.gnome.org/show_bug.cgi?id=728940
Application that shows how to integrate playbin with an OpenGL ES
scene through EGL. Renders a video on the surfaces of an animated cube.
The code is not ported to 1.x so it's not built by default.
