53ee84f811 lavc/ccaption_dec: reap_screen() is responsible for clearing output buffer and signaling screen_changed
moves the screen_changed bit and the bprint_clear into reap_screen() so
the logic is centralized and callers do not need to touch the bit or the
buffer before calling reap_screen()

6f1466dc52 lavf/matroskadec: A_QUICKTIME and fourcc 0x00000000
In many older QuickTime files, the audio format, or "fourcc", is
0x00000000. The QuickTime File Format Specification states the following
regarding this situation:

"This format descriptor should not be used, but may be found in some
files. Samples are assumed to be stored in either 'raw ' or 'twos'
format, depending on the sample size field in the sound description."

MPlayer handles this logic by itself, but FFmpeg/FFplay currently does
not.

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.
