Based on the libavfilter SOC filter by Vitor Sessak, with the following additions:
* integer arithmetic
* bilinear interpolation
* RGB path
* configurable parametric angle, output width and height
Address trac issue #1500.

Date: 2010-10-03 17:35:49 GMT
From various tests, there is no evidence that the filter is faster than
the native tinterlace, and it has several more limitations and a few
bugs.

Same funcionality is provided by stereo3d=ab[2]{l,r}:sbs[2]{l,r}.
Additional "features" are barely useful and cause crash or artifacts.

The next commit will introduce a proper decimation filter to be used
along with the field matching filter. To avoid confusion with this
filter which has currently a very limited usage (and will not work
properly with the fieldmatching filter), the new decimation filter will
take the decimate name, and this filter is renamed to mpdecimate.

Ported from MPlayer. Original author is A'rpi, with various
contributions from Michael Niedermayer. The original documentation was
mostly written by Diego Biurrun. See the MPlayer history for full
credits.
The filter is under GPL like the original filter, even if it differs
quite a lot. There is not much point in making it LGPL since pp is under
GPL.
This filter pads an audio stream with silence
It can together with -shortest be used to extend audio streams to
the same length as video.

The file now contains also an audio select implementation. Also move the
aselect/select documentation from video filters to the multimedia filters
section.
This matches the naming style of the new af_volume_justin filter.
Note, Yes i would too prefer having one filter instead of 2.

Since the recent changes, movie and amovie are able to deal with more
than one type of stream, so they should be categorized as "multimedia
sources" rather than audio/video sources.
These filters are designed for storing and transmitting video sequences
with alpha using higher-efficiency codecs such as x264 which don't
natively support an alpha channel. 'alphaextract' takes an input stream
with an alpha channel and returns a video containing just the alpha
component as a grayscale value; 'alphamerge' takes an RGB or YUV stream
and adds an alpha channel recovered from a second grayscale stream.
