Hello I trying also to convert a single jpg/image to a videostream but i 
dont understand how to set a framerate on the sink cap of jpegdec , I try :
gst-launch filesrc location=dvCatpure.jpeg ! image/jpeg , 
framerate=\(fraction\)1/1 ! jpegdec  !videoscale ! ffmpegcolorspace ! 

But the streaming stops after one frame
