ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Thu Jul 30 21:44:51 2020 +0200| [8129c32e488645db325263a6bee01311b83e7ed9] | committer: Andreas Rheinhardt

avcodec, avfilter, avformat: Remove redundant avpriv_align_put_bits

flush_put_bits() already fills the bitstream with zeroes, so it is
unnecessary to align the bitstream before.
