Matthew Waters 0e404ae3fc glsyncmeta: add vfuncs for all operations

Vineeth TM a0a8b8873b glsl: fix possible string overrun in gst_glsl_version_profile_from_string 
given a NULL-terminated string, s.
s[i] = '\0';
i++;

could read off the end of the array.

Matthew Waters 148940c456 glshader: don't read invalid list pointers (use after free) 
gst_gl_shader_detach_unlocked already removes the list entry so attempting to

Matthew Waters b30deff7e1 glcolorconvert: mangle gl_FragColor for GL3 
Some drivers don't provide the compatibility definition and we need to provide
our own 'out vec4' variable to put the results of the fragment shader into.

Matthew Waters b8c1ecf268 glviewconvert: remove set_format

Matthew Waters 117fc0409a glshader: properly unref the stages on failure 
When failing in the varargs functions, all the stage objects not handled need to
be unreffed to prevent a leak.
 2017-12-09 19:32:11 +00:00
Matthew Waters 1f35fcf06d glslstage: properly return an error when we could not create the shader stage 
While it was erroring out correctly later, there were GLib warnings about
setting a GError over the top of another GError.
 2017-12-09 19:32:10 +00:00
Matthew Waters ef319c7b8f glshaderstrings: fixup the external-oes fragment shader

Matthew Waters 105497de60 glcolorconvert: try to keep the same texture-target if possible

Matthew Waters 46b84c6035 glcolorconvert: fix rendering rectangular textures with GL3 
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()
 2017-12-09 19:32:10 +00:00

Alessandro Decina 7fedb34bea gstglutils: fix shader compilation on Mountain Lion 
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.
 2017-12-09 19:32:10 +00:00
Matthew Waters d41e6a5579 glbufferpool: explicitly initialize a possibly uninitialized variable 
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...)
 2017-12-09 19:32:10 +00:00
Matthew Waters b0d40019f9 glslstage: remove typedefs from the header 
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.
 2017-12-09 19:32:10 +00:00
Matthew Waters 2595f73fd0 glcolorconvert: follow the correct texture target names 2017-12-09 19:32:10 +00:00
Matthew Waters 434bbc9f01 glupload: explicitly configure the texture target on the gl buffer pool 
If we don't, then the pool could end up allocating 2D textures when the
caps explictly state they should be rectangle textures.
 2017-12-09 19:32:10 +00:00
Matthew Waters 18f9dfdfe5 glbufferpool: add bufferpool options for the various texture targets 
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.
 2017-12-09 19:32:10 +00:00
Matthew Waters 6141d3fc7e glcolorconvert: add support for converting texture targets 
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.
 2017-12-09 19:32:10 +00:00
Matthew Waters 681cb5b16d glmemory: add support for rectangle 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.
 2017-12-09 19:32:10 +00:00
Matthew Waters aa32408926 glcolorconvert: order the caps template so that RGBA is first 
glcolorconvert ! glcolorconvert would sometimes negotiated RGB
(the first list entry) otherwise.
 2017-12-09 19:32:10 +00:00
Matthew Waters 33f73b400d glbufferpool: move typedef's into the forward decleration file 
Otherwise, for example, clang will warn about typedef redefinitions
being a C11 feature.
 2017-12-09 19:32:10 +00:00
Julien Isorce 6bb560a4eb glslstage: initialize output params to 0 before calling gl functions 
The client side API of the Chromium's GPU Process has asserts
in debug mode that check that output params are initialized to 0.
 2017-12-09 19:32:10 +00:00
Matthew Waters ad49a39e5b glcolorconvert: allow outputting multiple textures for gles3 contexts 
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.
 2017-12-09 19:32:10 +00:00
Matthew Waters cfb0d7e9f3 glviewconvert: expose the element on gles2 platforms 
We can do everything with gles3 however gles2 restricts us not allowing
separated or frame-by-frame multiview modes due to multiple draw buffers.
 2017-12-09 19:32:09 +00:00
Matthew Waters 764c4a33bc gl: fix usage of string.h and stdio.h functions without including the headers

moves/changes/etc.

Matthew Waters f688a8f0b2 glshader: port to using GstGLSLStage objects for string management 
A GstGLShader is now simply a collection of stages that are

interface has remained the same.
 2017-12-09 19:32:09 +00:00
Matthew Waters 8c922ca96b glsl: add a shader stage object GstGLSLStage

Matthew Waters 18e205dcbb gl/shader/variables: include generic gl.h header

Matthew Waters 332543f3cf gl: add some GLSL utility functions

Matthew Waters 0580536fa1 glutils: use gst_element_set_context for setting display/other_context

   GstContext->GstGLDisplay/GstGLContext transformation occurs
3. Fixes a memory leak in the process
4. Make the retrieval of debug categories thread safe

Matthew Waters 63bbe9406a glwindow: add API to request a resize event on the next draw 
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.

Matthew Waters d45e0f807f glbasefilter: only call gl_{stop,start} if the context changed 
Removes the redundant GL object creation/deletion on every

Depending on the bytes order we will get BGRA (little) and ARGB (big)
from the composition overlay buffer while our GL code expects RGBA. Add
a fragment shader that do this conversion.

assertion here.

As we don't print debug output for any of the other transform functions, let's
defer this problem for now.

Matthew Waters 78957c45c2 glcontext: track sharedness with a cookie 
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.
