<div class="gmail_quote">2009/6/25 Phil Rendell <<a href="mailto:philrendell@gmail.com">philrendell@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> There is only one filter under the Video Capture Sources group: the Microsoft DV Camera and VCR. There are two output pins: DV A/V Out and DV Vid Out. All of the properties in DV A/V Out are disabled and are either empty or set to 'None', with the exception of the color space/compression (which is probably the one we're interested in) which is set to dvsd. The properties for DV Vid Out are the same as above, but without the color space/compression set. </blockquote></div> Then I think gst-launch-0.10 dshowvideosrc ! fakesink can play (I should ask you first) because dvsd is ok with the current implementation. But in this case I can see from the implementation that dshowvideosrc outputs video/x-dv You should see it using -v option. Anyway, ffmpegcolorspace doest not handle video/x-dv, that's why you got "WARNING: erroneous pipeline: could not link dshowvideosrc0 to ffmpegcsp0" Then you could try to insert a ffdec_dvvideo (if you have it) bettween dshowvideosrc and ffmpegcolorspace. (note that I do not know if gstreamer has a dv decoder that does not come from gst-ffmpeg) Sincerely Julien
