3b9b30563e glimagesink: Don't leak other-context 2017-12-09 19:31:48 +00:00

6491af9ffc 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.

7b1a853888 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.

84a50aefe1 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.

8196b9629c 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.

30c6efc432 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).

Should not lose any features/video formats.

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream
