Hi Andrew,
Another way you could probably knock something up quickly is using
gstreamer - v0.10 contains a DV de/payloader:
%gst-inspect-0.10 | grep "dv:"
typefindfunctions: video/x-dv: dif, dv
dv: dvdemux: DV system stream demuxer
dv: dvdec: DV video decoder
ffmpeg: ffdemux_dv: FFmpeg DV video format demuxer
ffmpeg: ffmux_dv: FFmpeg DV video format muxer
You could play with creating a pipeline using gst-launch-0.10 to do
what you want or you can write a small app in Python or C++ using the
gstreamer libraries.
