add RGB to NV12 and NV12 to RGB conversion
- either is implemented in 2 ways: 8.8 fix point or float point
however, it doesn't show performance difference in my test
- RGB to NV12 conversion can be used to load video frames for futhure
processing
- NV12 to RGB conversion can be used for fine control of video rendering:
for example: RGB565 support, color correction
- for RGBX layout, we follows BMP image, that is: |B|G|R|X| in memory layout
Zhao Halley (4):
add GPU shader for RGB->NV12 conversion
add rgbx->nv12 conversion in post-processing
add GPU shader for NV12->RGBX conversion
add nv12->rgbx conversion in post-processing
