r277 completes RGB to/from ARGB adds I411ToARGB:
Conversion Number Maximum Completeness
YUV <-> I420 31 32 96.88%
RGB <-> I420 24 24 100.00%
YUV <-> ARGB 15 32 46.88%
RGB <-> ARGB 24 24 100.00%
Of the 28 formats, 24 can be converted to ARGB. 85.71% complete.
Missing are MJPG, M420, Q420, V210.
M420 is similar to NV12. Q420 and V210 are similar to YUY2.
NV12 internally is similar to how I420ToARGB_SSSE3 works.

r281 completes anything to ARGB:
Conversion Number Maximum Completeness
YUV <-> I420 31 32 96.88%
RGB <-> I420 24 24 100.00%
YUV <-> ARGB 18 32 56.25%
RGB <-> ARGB 24 24 100.00%
Conversion Number Maximum Completeness
YUV 55 56 98.21%
RGB 42 56 75.00%
Of 28 formats, 26 can be converted to ARGB. 25 directly with 1 pass assembly.
MJPG is 2 steps - decode to YUV macro blocks and convert macro blocks to ARGB.
The 2 formats that are not supported are Q420 and V210 which are experimental.
M420 was last to be done - its very similar to NV12, but row interleaved
instead of biplanar.
ToI420 100.00%
FromI420 96.43%
ToARGB 92.86%
FromARGB 57.14%
Overall 90.18% 97 out of 112 conversions, 75 direct.
Most important missing functionality is I420ToMJPG, but this is not key for
webcam support.
