YUY2ToI420 is slow on Arm #64

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On Arm platforms that use YUY2 camera format, the conversion is #1 on profiles.
Its using C code, and should be converted to Neon.
Code should be similar to NV12

Note YUY2ToARGB has Neon for the ARGB portion of the conversion.

r375 has NEON YUY2ToI420.  And UYVYToI420.
Keeping bug open as the register usage should be cleaned up to avoid pushes.
