Let me explain how the ARM feature selection in FFmpeg works. First, there is
the question of runtime feature detection.
This is not done on ARM for two reasons: 1) building the entire code for the
correct target makes a big difference in
performance, and 2) there is currently no good way to det
Ugh, sorry about the line breaks.

You should run configure with --cpu=cortex-a8 or --cpu=armv7-a. Do not
use --extra-cflags for the -mcpu or -march flags, as this will not give
optimal settings. Specifically, it will not allow FFmpeg to use
unaligned memory accesses even though armv6 and later supports them.
