Richard Stanway	a3c97dfad2	libobs-opengl: Miscellaneous static analysis fixes Detected by PVS Studio.	2022-01-15 23:02:38 +00:00
jpark37	66259560e0	libobs: Add dormant SRGB format support GS_RGBA, GS_BGRX, and GS_BGRA now use TYPELESS DXGI formats, so we can alias them between UNORM and UNORM_SRGB as necessary. GS_RGBA_UNORM, GS_BGRX_UNORM, and GS_BGRA_UNORM have been added to support straight UNORM types, which Windows requires for sharing textures from D3D9 and OpenGL. The D3D path aliases via views, and GL aliases via GL_EXT_texture_sRGB_decode/GL_FRAMEBUFFER_SRGB. A significant amount of code has changed in the D3D/GL backends, but the concepts are simple. On the D3D side, we need separate SRVs and RTVs to support nonlinear/linear reads and writes. On the GL side, we need to set the proper GL parameters to emulate the same. Add gs_enable_framebuffer_srgb/gs_framebuffer_srgb_enabled to set/get the framebuffer as SRGB or not. Add gs_linear_srgb_active/gs_set_linear_srgb to instruct sources that they should render as SRGB. Legacy sources can ignore this setting without regression. Update obs_source_draw to use linear SRGB as needed. Update render_filter_tex to use linear SRGB as needed. Add gs_effect_set_texture_srgb next to gs_effect_set_texture to set texture with SRGB view instead. Add SRGB helpers for vec4 struct. Create GDI-compatible textures without SRGB support. Doesn't seem to work with SRGB formats.	2021-01-21 07:42:13 -08:00
jp9000	f53df7da64	clang-format: Apply formatting Code submissions have continually suffered from formatting inconsistencies that constantly have to be addressed. Using clang-format simplifies this by making code formatting more consistent, and allows automation of the code formatting so that maintainers can focus more on the code itself instead of code formatting.	2019-06-23 23:49:10 -07:00

Alex Anderson	4eac034814	libobs-opengl: Add int2-4 support Closes obsproject/obs-studio#1506	2018-09-28 13:59:49 -07:00
jp9000	4dc0024198	libobs/graphics: Add ability to set shader texture sampler (Note: This also modifies libobs-d3d11 and libobs-opengl) Allows overriding the sampler for a specific shader parameter.	2016-06-29 04:15:38 -07:00
jp9000	ccfd57d100	libobs/graphics: Rename inconsistent function names Renames functions: gs_shader_setmatrix3 -> gs_shader_set_matrix3 gs_voltexture_getdepth -> gs_voltexture_get_depth	2015-10-21 07:46:43 -07:00
jp9000	86e56a5c4e	libobs-opengl: Do not fail if shader param unused I encountered a scenario where effects might reference shader parameters that may not potentially exist, this isn't particularly a bad thing that needs to return failure. It just needs to gracefully ignore it.	2015-03-22 18:38:46 -07:00
jp9000	84d16fed8e	libobs-opengl: Assign texture units to shader vars Texture units were not being properly associated with the shader uniform variables.	2015-03-22 18:38:45 -07:00
jp9000	41fad2d1a4	(API Change) Use const params where applicable This Fixes a minor flaw with the API where data had to always be mutable to be usable by the API. Functions that do not modify the fundamental underlying data of a structure should be marked as constant, both for safety and to signify that the parameter is input only and will not be modified by the function using it.	2014-09-26 17:23:07 -07:00
GoaLitiuM	10f5d7f3aa	Fixed NULL pointer dereferencing in linked lists	2014-09-27 01:35:36 +03:00
jp9000	c9df41c1e2	(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.	2014-09-25 21:48:11 -07:00
jp9000	3967c6354a	Replace ARB_separate_shader_objects extension This replaces the ARB_separate_shader_objects extension with traditional linked shaders. I was able to get the existing system to use linked shaders without having to change any libobs graphics API. This essentially creates a linked list of shader programs with references to the shaders they link. Before draw, it searches that linked list for a particular pixel/vertex shader pair, and the linked program associated with it. If no matching program exists, it creates the program.	2014-09-19 18:23:51 -07:00
jp9000	4654eca6b8	Remove GL shader debug text	2014-08-21 03:04:20 -07:00
jp9000	5780f3f177	(API Change) Improve graphics API consistency Summary: - Prefix all graphics subsystem names with gs_ or GS_ - Unsquish funciton names (for example _setfloat to _set_float) - Changed create functions to be more consistent with the rest of the API elsewhere. For exmaple, instead of gs_create_texture/gs_texture_destroy, it's now gs_texture_create/gs_texture_destroy - Renamed gs_stencil_op enum to gs_stencil_op_type From: To:

jp9000	cec11d624a	OpenGL: Don't call glGetAttribLocation on outputs Previously we were using glGetAttribLocation on all inputs/outputs and then just discarding if it was returned -1.
