Palana 824ff961d0 Enable GL vertex attribute normalization
Fixes GL vertex color attributes
2014-05-02 00:37:32 +02:00
jp9000 2dbbffe4a2 Make a number of key optimizations
- 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.

jp9000 966b943d5b Remove majority of warnings
There were a *lot* of warnings, managed to remove most of them.

Also, put warning flags before C_FLAGS and CXX_FLAGS, rather than after,
as -Wall -Wextra was overwriting flags that came before it.

jp9000 b067440f73 Use bzalloc instead of bmalloc then memset
Reduces needless code repetition and still allows for proper memory
alignment.  Cleans up the code a bit.

jp9000 8298fa4dc7 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+) 2013-12-02 22:24:38 -07:00
jp9000 e5c99175c5 fixed some build issues on non-windows systems 2013-11-26 23:07:27 -07:00
jp9000 10e917efee unbind VAO if NULL buffer specified 2013-11-15 07:07:03 -07:00
jp9000 72a64b3d41 added VAOs to vertex buffers (might need some future tweaking to check whether buffers are already assigned to specific attributes) 2013-11-15 06:34:05 -07:00
Palana ebc78eee9d do not unbind vertex array (GL 3+) 2013-11-14 17:51:38 +01:00
jp9000 dfa2dc6eab fix up the rest of the GL code, add glew to project, add makefiles for opengl, fix makefiles so that it can be built with gcc, update project files to automatically output to the build directory 2013-10-16 23:31:18 -07:00
