Hi Luís.
If I try your statements on my computer, I get an gstreamer error. This may be the result of a mission codec.
However, a good way to prove that the issue isn't related to the gstreamer usage would be to plug both ends directly together without a DTN in between.

Your statement would look like this...
gst-launch v4l2src device=/dev/video1 ! video/x-raw-yuv, \ width=320,height=240,framerate=10/1 ! ffmpegcolorspace ! smokeenc \ keyframe=8 qmax=40 ! fdsink fd=1 | \ gst-launch fdsrc ! smokedec ! ffmpegcolorspace ! fakesink dump=true \ async=false
If this isn't working, you should solve that first. Maybe a gstreamer Mailinglist is a better place to ask for those questions, since I think there is no video expert on this list.
Kind regards, Johannes
