Currently supported source pixel formats are:
- PIXEL_FORMAT_BGRA32
- PIXEL_FORMAT_BGRX32
Support for PIXEL_FORMAT_RGB[XA]32 can simply be added if
required (see the comment in prim_YUV_opt.c).
On my old 3.1 GHz Core i5-2400 the new SSSE3 function can convert
over 900 1080p BGRX frames per second.
The current non-optimized C version (which supports all pixel formats)
can't do more than 40 yuv conversions per second on this cpu.
---------------------------+---------+-------------+-----------+-------
RGB TO YUV420 1080p 32bit | COUNT | TOTAL | AVG | FPS
---------------------------+---------+-------------+-----------+-------
general_RGBToYUV420 | 500 | 13.1776s | 0.026355s | 38
ssse3_RGBToYUV420 | 500 | 0.5320s | 0.001064s | 940
Also fixed an error in TestPrimitivesYUV which generated resolutions
with height or width set to zero
- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
CMake 2.8 does not support default visibility on windows.
To allow building tests add the FREERDP_LOCAL define for each
function that is internal to FreeRDP.
When build with testing these functions are exported and available
for use by tests.
win32/msvc cc does not recognize the %z format specifier which caused
invalid references and segfaults on win32.
Until FreeRDP gets format specifier macros we'll cast size_t to
unsigned long and use the %lu specifier.
Also simplified winpr_backtrace_symbols() a little bit and fixed it
to allocate the correct amount of bytes for the return buffer.
