No problem - without your help I would be completely stuck and end up being forced to do something drastic like hunt around in the source code before giving up! > Phil, can you tell me if > gst-launch-0.10.exe dshowvideosrc ! "video/x-dv, systemstream=false, > width=640, height=480, framerate=10" ! fakesink > leads to the same result as true ? No, it doesn't. It gives me the usual link error: D:\Camera\Common\GStreamer\bin>gst-launch-0.10.exe -v dshowvideosrc ! "video/x-dv, systemstream=false, width=640, height=480, framerate=30" ! fakesink WARNING: erroneous pipeline: could not link dshowvideosrc0 to fakesink0 > About the screenshot.

Ok, thanks. > Anyway, for now I just do not know how to decode or render a video/x-dv, > systemstream=true. > I am sure someone else knows ? Good idea with the ffdemux_dv. The command you suggested didn't quite work, but once I added the dv decoder you suggested in a previous email and added a deinterlacer I managed to get something to display, although I ended up with a pretty bad 0.5-1 fps.
