The purpose of this filter mode is to allow interlaced content to
display properly in interlaced video modes, as described in
http://forum.xbmc.org/showthread.php?tid=81834 and
https://github.com/mpv-player/mpv/issues/624#issuecomment-37685195 . The
filter doubles the video frame rate, but does not work properly because:
(1) it does not set the properties of the output stream to indicate the
doubled frame rate, and
(2) it does not set an appropriate PTS on the extra frames.
The attached patch fixes these problems by settling these values the
same way they are set in vf_yadif mode 1 (field) which also doubles the
frame rate.

The next commit/bugfix will need it
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

mp4 files embedding DVD subtitles do not use the same extradata format
as the rest of Libav expects. The subtitle decoder in libavcodec in
particular does not understand this format.

Convert the extradata to the vobsub .idx format. mp4 stores the palette
as binary 32 bit ints in YUV. The subtitle resolution is stored
separately in the track header, which we access through AVStream.

These ADPCM codecs include a per-frame flag that enables a raw 16-bit mode. Therefore
the the number of samples returned by get_nb_samples() is only ever approximate.
