Rectangular textures are unavailable in unextended
GLES2 #version 100 shaders.
Fixes
texture-target=rectangle ! glcolorconvert ! texture-target=2D
There's a couple of differences between GL3 and GLES2/GL
- varying -> in or out depending on the stage (vertex/fragment)
- attribute -> in
- filtered texture access is a single function, texture()
Bitrate estimation is now handled through a queue2 element added after
the source element used to download fragments.

This code will never be called as max>=min in all cases. If the upstream
latency query returned min>max, the function already returned and all
values that are added to those have max>= min.
Make gst_gl_context_gen_shader/_compile_shader assume GST_GLSL_PROFILE_ES |
GST_GLSL_PROFILE_COMPATIBILITY as the profile. Without this, the shader compiler
doesn't inject the #version tag resulting in a compilation error on Mountain
Lion.
This is a workaround for old code using gst_gl_context_gen_shader. New code
should use the gst_glsl_stage_* API directly which allows the caller to
explicitly specify version/profile.
The ret variable may be uninitialized and so its contents were undefined and
the results were erratic (failing with glvideomixer, succeeding in other cases)
P.S. No idea why gcc/clang et al never picked up on this like they normally do
(probably due to some optimisation pass figuring out it's only set once...)
They are already defined in the forward decleration header and defining them
more than once will give an error with OSX's clang about typedef redefinition
being a C11 feature.
This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps. Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.
This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.
Solved with a simple shader templating mechanism and string replacements
of the necessary sampler types/texture accesses and texture coordinate
mangling for rectangular and external-oes textures.
Add the various tokens/strings for the differnet texture types (2D, rect, oes)
Changes the GLmemory api to include the GstGLTextureTarget in all relevant
functions.
Update the relevant caps/templates for 2D only textures.
The gst_adaptive_demux_stream_free function is trying to stop the stream's
download task. For this, it signals the task. But it fails to also set the
stream->download_finished = TRUE, so the task will go back to sleep and
only exit when the download is finished.

Initialize to 0 these parse structures before filling them: GstH264SEIMessage,
GstH264NalUnit, GstH264PPS, GstH264SPS and GstH264SliceHdr.
When calling the functions which fill those structures, they may fail, leaving
unitialized those structures. This situation may lead to future problems, such
as a segmentation fault when freeing, for example.
This patch initializes to zero these structures, before filling them.

the USING_GLES2 includes all GLES3 contexts as well which does support
drawing to multiple buffers. Instead make or decision solely based on
whether glDrawBuffers is available or not.
Not all aggregator subclasses will have a single pad template called sink_%u
and might do something special depending on what the application requests.
