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.
Adds more log information for effects, such as the reformatted effect code, parameters, techniques and passes. This is useful for tracking down issues and what actually ends up being compiled in the end, without having to guess where the error is actually at, as what is compiled and what was originally there usually differ by a lot.
This information is only logged if libobs is compiled in debug and _DEBUG_SHADERS is defined and not compiled if either of those are not the case.
Gives the ability to retrieve param annotations. Blocks wrapped in <>
following a parameter.
For example:
float slider < float max_value = 10.0; float min_value = 0.0; >;
These blocks are not for shading purposes but to help describe the
shader's gui as in the example above.
Adds graphics api functions for retrieving annotations:
size_t gs_param_get_num_annotations(const gs_eparam_t *param);
gs_eparam_t *gs_param_get_annotation_by_idx(const gs_eparam_t *param,
size_t annotation);
gs_eparam_t *gs_param_get_annotation_by_name(const gs_eparam_t *param,
const char *name);
Added cast to unsigned and the assert because microsoft's compiler
doesn't support "%zu"
Actual warning:
libobs/graphics/effect-parser.c:1387:4: warning: format specifies type
'unsigned int' but the argument has type 'size_t' (aka 'unsigned long')
[-Wformat]
If negative was specified it would not parse the negative sign and thus
would not interpret that number as negative, and would cause
shader/effect parsing to simply fail on the file.
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.
- Signals and dynamic callbacks now require declarations to be made
before being used. What this does is allows us to get information
about the functions dynamically which can be relayed to the user and
plugins for future extended usage (this should have big implications
later for scripting in particular, hopefully).
- Reduced the number of types calldata uses from "everything I could
think of" to simply integer, float, bool, pointer/object, string.
Integer data is now stored as long long. Floats are now stored as
doubles (check em).
- Use a more consistent naming scheme for lexer error/warning macros.
- Fixed a rather nasty bug where switching to an existing scene would
cause it to increment sourceSceneRefs, which would mean that it would
never end up never properly removing the source when the user clicks
removed (stayed in limbo, obs_source_remove never got called)
- 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.
