[x264-devel] [PATCH] Fix mc_chroma NEON code for NV12

[Stefan Grönroos]

Hello guys!

The attached patch changes the x264_mc_chroma_neon to work with the NV12
format. With quick tests, the code seems to give about 15% higher fps on a
Nokia N900 using a Foreman CIF test video on default settings.

Still, the instruction ordering should maybe be optimized still. I also have
a feeling that I thought something could be done better when I wrote it, but
I don't remember what it was. Maybe someone more into NEON could take a look
at the code?

Best regards,
Stefan Grönroos
