[Bug 746251] android/gl: video does not show up / GL errors

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=746251

--- Comment #5 from Matthieu Bouron <matthieu.bouron at collabora.com> ---
The issues happens when the window handle is changed by the application (here
the android tutorial-5 when it detects a resolution change as it tries to adapt
the surface to the new size).
It does not happen with a simple pipeline with no window handle change, sorry
for the dramatic title.

The first critical error happens when gst_gl_context_activate (context, TRUE)
is called from gst_gl_window_set_window_handle as glimagesink has detected a
window handle change.

It fails to create the surface texture with the following error:

gstglcontext_egl.c:536:gst_gl_context_egl_activate:<glcontextegl1> Failed to
create window surface: EGL_BAD_ALLOC

It is likely that some ressource are leaked / not properly de-initialized
somewhere.

I have attached a patch that adds error logging in gst_gl_context_egl_activate
and make the function fails if the surface is not created (even if the return
code is not checked by its caller).

I will continue my investigation.
