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.

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.
