e40d70c69a gl: propogate other-context using GstContext 2014-10-23 23:58:33 +11:00

302034ac4c glimagesink: Only finalize the other context in finalize() 
Otherwise we change a value of a property when going to READY state,
which is unexpected behaviour.

5b8d7a443e glupload: provide the output buffer that is rendered into 
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

4dacc4ba55 GstGLWindow, GstGLImagesink, x11: Scale navigation events on resized windows 
If window is resized, GstStructure pointer values have to be rescaled to
original geometry. A get_surface_dimensions GLWindow class method is added for
this purpose and used in the navigation send_event function.

13960f0043 glimagesink: keep the uploaded buffer around on successful redisplay 
We might need it later to perform a redisplay.  GstGLUpload will take
of releasing the previous buffer when it receives a new buffer.

ab29217726 glimagesink: Keep aspect ratio by default 
The expected default behaviour for video sink is to maintain the
aspect ratio. Fix the default value to reflect this. The property
default was already TRUE, but the value was not initially TRUE.

15d0c04933 gl/mem: allocate the memory per plane 
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).
