NAME
smil2yuv - Convert a Raw DV stream to Raw YUV.
SYNOPSIS
smil2yuv [ options ] file ...
DESCRIPTION
smil2yuv converts a Kino smil project or compatible media content into
the simple uncompressed planar 4:2:0 Y'CbCr format, as used by the
MJPEG Tools.
OPTIONS
-a audio-out-file
Output to an audio file in parallel. Type is based on the
extension and currently only wav and mp2 are provided. If you
wish to have more control over the mp2 file generated, export to
a wav first and then convert the wav as required.
-i type
Deinterlacing type - 0 is none, 1 provides very poor
deinterlacing (default: 0). 2 results in no interlacing, but a
4:1:1 subsampled stream (native NTSC DV) which can be processed
by y4mscaler. More types will be supported in the future.
-o offset
Output starts at the given frame offset (default: 0).
-f count
Output only contains the number of frames specified by count
(default: all).
-s speed
Specify the speed of reading the smil input - any floating
point number > 0 is applicable. So to halve the playback
rate, specify a speed of 2, to double it, specify a speed of
0.5.

EXAMPLES
To convert a mixture of raw dv, smil and avis of 48khz audio to divx:
smil2yuv raw.dv project.smil type1.avi type2.avi -a temp.wav -i 1 |
yuv2divx -o output.avi -A temp.wav -a 128
rm temp.wav
Or to play the stream via yuvplay:
smil2yuv input | yuvplay
Or to encode to VCD:
smil2yuv file.dv -i 1 -a test.mp2 |
yuvscaler -O VCD |
mpeg2enc -o test.mpv -f 1
mplex -f 1 test.mpv test.mp2 -o test.mpg
rm test.mpv test.mp2
KNOWN BUGS
* Mixtures of audio sampling in a project are handled by badly
resampling (anyone care to provide a better resampler? ta).
* Mixtures of PAL/NTSC aren't supported
* Deinterlacing produces pretty noisy/large files - planning to provide
better deinterlacing techniques through use of the tvtime deinterlacing
plug-ins.
