Progress update:
1. speed up unittests. Done. Was 5 minutes. Now 10 seconds.
try server and build bots added to libyuv.
valgrind added. tsan and asan pass. TODO memcheck.
webrtc has additional unittests and builds/runs bots, including Android.
RGBA to/from ARGB added and optimized for SSSE3.

RGBA to/from I420 optimized for SSSE3.

NEON optimized I420ToRGBA. RGBA, ARGB, BGRA and ARGB are all supported.
Re
f) ConvertYUY2ToYUV: no need to use libyuv
libyuv version is fully optimized for SSE2.
NEON version coming soon.
g) ConvertNV21ToYUV: no need to use libyuv
libyuv version is fully optimized for NV12/21, on NEON and SSE2 and including
fully register based rotate by 90/180/270. 32 bit version rotates 8x8 blocks
while 64 bit rotates 16x8.
NV12 is the most common mobile format, so rotation is important.
Also NV12ToARGB is a one step direct conversion with SSSE3, and theres an
NV12toRGB565 for mobile.

r431 ARGBToRGB565/555/4444 optimized for NEON.
f) g) optimized unaligned versions of YUY2 and NV12 for Neon and SSSE3.

r548 optimizes YUV bilinear scale for SSE2 (was SSSE3).

Step 1 complete. RGB to YUV and YUV to RGB use libyuv. 10% overall
performance improvement.

RGBToI420 tested for Chrome media capture. 20x faster (was C)

RGBAToBGRA used. Now optimized for AVX2 and SSE2, as well as SSSE3 and Neon
circa r810.

A number of media functions now use libyuv. The main unsatisfied requirement
is YUV to ARGB scaling.

Closing overall issue. libyuv is in use in various parts of chromium.
Open specific bugs for followup.
