2fbdc4faf1 lavfi/avf_showspectrum: replace pow(x, 0.25) by sqrt(sqrt(x)) 
This is faster; precision assured as result is a float.

72673ad7ea avcodec: Remove libstagefright 
It serves absolutely no purpose other than to confuse potentional
Android developers about how to use hardware acceleration properly
on the the platform. The stagefright "API" is not public, and the
MediaCodec API is the proper way to do this.

Furthermore, stagefright support in avcodec needs a series of
magic incantations and version-specific stuff, such that
using it actually provides downsides compared just using the actual
Android frameworks properly, in that it is a lot more work and confusion
to get it even running. It also leads to a lot of misinformation, like
these sorts of comments (in [1]) that are absolutely incorrect.

a956840cbc ffmpeg: check return value of avio_closep for progress report 
avio_closep is not guaranteed to succeed, and its return value can
contain information regarding failure of preceding writes and silent
loss of data (man 2 close, man fclose). Users should know when the
progress was not successfully logged, and so a diagnostic is printed
here.

This gets rid of some branches to speed up table generation slightly

tested with FATE.
