Hi,<br><br>To clarify, like others said, ffmpeg can decode the DV codec in general (ie, you can plug a camera in and view it) but it apparently can't depacketize DVTS, since when you try to receive a DVTS stream it just looks like noise. VLC can do neither as far as I can tell.<br>
<br>Piers - thanks for the info, I'll give gstreamer a try.<br><br>Andrew - what are you using as the backend for this transcoding tool? Is it all custom-written or do you rely on libraries like ffmpeg?<br><br>--Andrew<br>

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