There don't appear to be any GPUs that support 3.2, but not 3.3. GLSL 330 maps to HLSL Shader Model 4, so this will theoretically make shaders programs less likely to diverge, particularly for behavior around NaNs.

When mixing sampling with raw loads in a shader, ending a shader with a load would case the default sampler to become unset for OpenGL. Instead, initialize with no sampler, and only set if there is a sampler.

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.

The cache coherency of rasterization for full-screen passes is better using an oversized triangle that is clipped rather than two triangles. Traversal order of rasterization is GPU-specific, but will almost certainly be better using an undivided primitive. A smaller benefit is that quads along the diagonal are not evaluated multiple times, but that's minor in comparison. Redo format shaders to bypass vertex buffer, and input layout. Add global shader bool "obs_glsl_compile" to make API-specific decisions, i.e. handle upside-down UVs. gl_ortho is not needed for format conversion because the vertex shader does not use ViewProj anymore. This can be applied to more situations, but start small first. Testbed full screen passes, Intel HD Graphics 530: RGBA -> UYVX: 467 -> 439 us, ~6% savings UYVX -> uv: 295 -> 239 us, ~19% savings

This is supposed to assign -1 to the sampler_id to indicate that no sampler need be assigned for the texture, but instead it was leaving the variable with uninitialized data, resulting in a crash when used.

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.

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:

- Changed glMapBuffer to glMapBufferRange to allow invalidation. Using just glMapBuffer alone was causing some unacceptable stalls. - Changed dynamic buffers from GL_DYNAMIC_WRITE to GL_STREAM_WRITE because I had misunderstood the OpenGL specification - Added _OPENGL and _D3D11 builtin preprocessor macros to effects to allow special processing if needed - Added fmod support to shaders (NOTE: D3D and GL do not function identically with negative numbers when using this. Positive numbers however function identically) - Created a planar conversion shader that converts from packed YUV to planar 420 right on the GPU without any CPU processing. Reduces required GPU download size to approximately 37.5% of its normal rate as well. GPU usage down by 10 entire percentage points despite the extra required pass.

With the permission of my fellow contributors, I'm switching obs-studio back to GPL v2+ to prevent issues between this project and the original OBS project, and for personal reasons to avoid legal ambiguity (not political reasons, I admittedly would prefer GPL v3+)
