It was ported to a native libavfilter filter.

Partially based on the port by Niel van der Westhuizen
<nielkie@gmail.com>, done for GCI 2010. Same output as the original
filter and as fast.

See thread:
Subject: [FFmpeg-devel] [PATCH] Port MPlayer 2xSaI filter to libavfilter
Date: Thu, 25 Nov 2010 01:31:24 +1000

Remove unused variable size from video_encode_example() function.

Fix GCC warning:
decoding_encoding.c:214:22: warning: unused variable ‘size’ [-Wunused-variable]

The header is part of the public API, in particular is used by
doc/examples/filtering_audio.c.

All code should use the local variable, the
AVCodecContext might not yet have the updated value.

Fixes potential out-of-bounds writes.
This is mostly possible when muxing ALS files where from
an extradata size of about 1050 put_bits would write data
outside the buffer.

For the FATE test sample used, this only avoids a warning
message.
However for other samples like al05_44.mp4 the converted
file can be played only after this fix.

This will only work for DSEs that are first in a packet, but
that is enough to fix handling of the reference files in
fate-suite/aac (though most of them still have other issues).

If channel residues are have not been decoded from bitstream, they should be
initialized to 0 instead of using values from previous subframe.
This causes bursts of noise in silent parts of some files.

Otherwise for muxers like e.g. latmenc that never call
avio_flush (and do not have a write_trailer function)
a part of the data will always be missing.
Also update references for the voc muxer, which was also
buggy before and did not write out all data.

  movenc: small refactor mov_write_packet

  interplayvideo: fix av_dlog parameter type mismatch
  Drop some pointless #ifdefs.

Previously it would just silently write out incorrect data.
This also fixes a potential integer overflow in the allocation.

"Fix" in so far as at least it will no longer overread and possibly
crash and makes somewhat sense, but no idea whether there is anything
that can play the resulting files (FFmpeg can't).

Currently they end up twice in the binary, since both
encoder and decoder include the header and thus each gets
their own copy.
This is clearly nonsense for the const tables, but shouldn't
be necessary for the RLTable either.

av_freep()ing inside configure_video_filters() leaves a dangling
reference in the calling code, and the filter string is needed again when
reconfiguring video filters for a size change.

During failure conditions ff_h264_decode_init() leaks memory
allocated for nal units.  Found via valgrind.

Share the formerly internal write_packet with the hinter and move the
fragment flush logic to the user facing one since it is not concerned
about movtrack-only streams.
