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	f688a8f0b2	glshader: port to using GstGLSLStage objects for string management ... A GstGLShader is now simply a collection of stages that are compiled and linked together into a program. The uniform/attribute interface has remained the same.	2017-12-09 19:32:09 +00:00
Nicolas Dufresne	9fd57c9a6c	gloverlaycompositor: Also disable the blend when done	2017-12-09 19:32:07 +00:00
Nicolas Dufresne	d576a71e9a	gloverlaycompositor: Add shader to convert BGRA/ARGB -> RGBA ... 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. https://bugzilla.gnome.org/show_bug.cgi?id=752842	2017-12-09 19:32:07 +00:00
Nicolas Dufresne	df7bcb6ba7	gloverlaycompositor: Keep memory pointer alive ... Keep the composition memory pointer alive while it's being wrapped inside a GstGLMemory object. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
Nicolas Dufresne	8884aeba87	gloverlaycompositor: Pass buffer stride ... The overlay pixel buffer stride was not given back to the GL image. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
Nicolas Dufresne	b0546f9bfa	gloverlaycompositor: Hide GstCompsitionOverlay object ... This object is only used inside the compositor and does not need to be expose in libgstgl API. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
Nicolas Dufresne	1812c19291	composition-overlay: Positions are relative to texture ... The coordinate are relative to the texture dimension and not the window dimension now. There is no need to pass the window dimension or to update the overlay if the dimension changes. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
Lubosz Sarnecki	8abd2bbe35	gloverlaycompositor: Create own shader object ... Make gloverlaycompositor independent of the shader used in the sink. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
Luis de Bethencourt	3199b1b4a8	gloverlaycompositor: for loop initial declarations are only allowed in C99 mode ... Fixes compiler warnings	2017-12-09 19:32:06 +00:00
Lubosz Sarnecki	4d010efea1	gloverlaycompositor: Add GstGLOverlayCompositor class ... Manages the GstGLCompositionOverlay objects, caches already uploaded overlays and draws them. https://bugzilla.gnome.org/show_bug.cgi?id=745107	2017-12-09 19:32:06 +00:00
