Re: Basic libav profiling

Hi,

I put a build harness around libav and gathered some profiling data.

See:

bzr branch lp:~linaro-toolchain-dev/+junk/libav-suite

Thanks!

README.rst has the basic commands for running ffmpeg and initial perf results showing the hot functions. Dave, 20 % of the time is spent in memcpy() so you might want to have a look.

FWIW I usually suspect when the profiling info shows that helper functions are the hottest. It might be that a bigger input should be used to stress out the functions which do the real computation.

Thanks, Revital
