7d8d1f8206 glmemory: implement on top of glbasebuffer 
Provides convenient access to PBO usage.

Currently texture updates are coupled tightly to data transfers.

by processing each one, not just the first.

c06715bde6 glupload/download/convert: provide transform_caps functions 
Allows finer grain decisions about formats and features at each
stage of the pipeline.
Also provide propose_allocation for glupload besed on the supported
methods.

5f547c5600 gl: initial support for texture targets other than GL_TEXTURE_2D 
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

9a55a3f98c glmemory: use pbo's for download 
In order to use pbo's efficiently, the transfer operation has to
be separated from the use of the downloaded data which requires some
rearchitecturing around glcolorconvert/gldownload and elements
 2015-01-27 12:26:04 +11:00
Matthew Waters
d5c3693791 gl: split glcolorconvert usage from glupload 
the separation allows the transfer operation to occur in a separate
thread/time which may increase performance in specific circumstances.

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).

Should not lose any features/video formats.

b90d824626 [838/906] gl: Use GL_TEXTURE_2D instead of GL_TEXTURE_RECTANGLE 
We create our textures (in Desktop GL) with GL_TEXTURE_RECTANGLE,
vaapi attempts to bind our texture to GL_TEXTURE_2D which throws a
GL_INVALID_OPERATION error and as thus, no video.

Also, by moving exclusively to GL_TEXTURE_2D and the npot extension
we also remove a difference between the Desktop GL and GLES2 code.

Write forward declarations in another way to avoid

Raised when using i686-apple-darwin11-llvm-gcc-4.2
