Convert I420 YV12 to RGB in various formats, |
|
it rejects images that are not in 420 formats, |
|
it rejects images that don't have widths of multiples of 16, |
|
it rejects images that don't have heights of multiples of 2. |
|
Reject defers to C simulation code. |
|
|
|
Lots of optimizations to be done here. |
|
|
|
1. Need to fix saturation code. I just couldn't get it to fly with packs |
|
and adds, so we currently use max/min to clip. |
|
|
|
2. The inefficient use of chroma loading needs a bit of brushing up. |
|
|
|
3. Analysis of pipeline stalls needs to be done. Use shark to identify |
|
pipeline stalls. |
|
|
|
|
|
MODIFIED to calculate coeffs from currently selected color space. |
|
MODIFIED core to be a macro where you specify the output format. |
|
ADDED UYVY conversion which is never called due to some thing in swscale. |
|
CORRECTED algorithim selection to be strict on input formats. |
|
ADDED runtime detection of AltiVec. |
|
|
|
ADDED altivec_yuv2packedX vertical scl + RGB converter |

PERFORMANCE ANALYSIS |
|
|
|
The C version uses 25% of the processor or ~250Mips for D1 video rawvideo |
|
used as test. |
|
The AltiVec version uses 10% of the processor or ~100Mips for D1 video |
|
same sequence. |
|
|
|
720 * 480 * 30 ~10MPS |
|
|
|
so we have roughly 10 clocks per pixel. This is too high, something has |
|
to be wrong. |
|
|
|
OPTIMIZED clip codes to utilize vec_max and vec_packs removing the |
|
need for vec_min. |
|
|
|
OPTIMIZED DST OUTPUT cache/DMA controls. We are pretty much guaranteed to have |
|
the input video frame, it was just decompressed so it probably resides in L1 |
|
caches. However, we are creating the output video stream. This needs to use the |
|
DSTST instruction to optimize for the cache. We couple this with the fact that |
|
we are not going to be visiting the input buffer again so we mark it Least |
|
Recently Used. This shaves 25% of the processor cycles off. |
|
|
|
Now memcpy is the largest mips consumer in the system, probably due |
|
to the inefficient X11 stuff. |
|
|
|
GL libraries seem to be very slow on this machine 1.33Ghz PB running |
|
Jaguar, this is not the case for my 1Ghz PB. I thought it might be |
|
a versioning issue, however I have libGL.1.2.dylib for both |
|
machines. (We need to figure this out now.) |
|
|
|
GL2 libraries work now with patch for RGB32. |
|
|
|
NOTE: quartz vo driver ARGB32_to_RGB24 consumes 30% of the processor. |
|
|
|
Integrated luma prescaling adjustment for saturation/contrast/brightness |
|
adjustment. |
