de2d03e12f Merge "Add smart RGB->YUV conversion option -pre 4" 2014-08-15 11:07:49 -07:00
skal
3fc4c539aa Add smart RGB->YUV conversion option -pre 4 
New function: WebPPictureSmartARGBToYUVA()
This implement smart RGB->YUV conversion.

This is rather undocumented for now, and is triggered using '-pre 4'
preprocessing option.

This is slow-ish and use quite some memory, but should be improvable.
This is somehow a usable beta version.

bb4fc051bf gif2webp: Allow single-frame animations 
Some single-frame GIF images have a canvas larger than the frame rectangle. For
such images, we retain the ANMF, ANIM and VP8X chunks in the output WebP file.
This ensures that the full canvas width/height and frame offsets are retained.

46fd44c104 thread: remove harmless race on status_ in End() 
if a thread was still doing work when End() was called there'd be a race
on worker->status_. in these cases, however, the specific value is
meaningless as it would be >= OK and the thread would have been shut
down properly, but we'll check 'impl_' instead to avoid any potential
TSan/DRD reports.

6422e683af VP8LFillBitWindow: enable fast path for 32-bit builds 
also reduce the load size from 64 to 32 bits as the top 32 bits are
being shifted away in the operation.

the change is neutral speed-wise on x86_64 as is the change in load size
on x86, but it gives a slight improvement on 32-bit arm.
x86 is improved ~13%, 32-bit arm ~3.7%
aarch64 is untested but will likely benefit as well.
