080de371d8 lavc/ccaption_dec: extract capture_screen() for future use
unlike reap_screen(), capture_screen() can be used to populate buffer
without touching the timestamps. this is useful for upcoming commits
which implement a real time caption stream.

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.
