Both complained about an erroneous pipeline. I don't think this could be the same error as before with feeding dshowvideosrc into ffmpegcolorspace, as if I remover the systemstream property, or set it to either true or false, gst-launch crashes.

You said "as if I remover the systemstream property, or set it to either true or false"<br>but you got a link error with "video/x-dv, systemstream=1".
