Hello Sebastian,
                 like a below pipeline can be used,

gst-launch filesrc location=colorbar.jpg ! jpegdec ! ffmpegcolorspace !
videoscale ! freeze ! autovideosink

i am using a custom displaysink as per my hardware. my display plane size is
1920 * 1080.

so when in my displaysink, 

get_caps is called, i return

          gst_structure_set (structure,
              "width", GST_TYPE_INT_RANGE, 1, 1920,
              "height", GST_TYPE_INT_RANGE, 1, 1080,
              "framerate", GST_TYPE_FRACTION_RANGE, 0, 1, 100, 1, NULL);
        }

so in set caps, for an image of resolution say 1920*1920, i get width=1920 and
height 1080 but i should get width 1080 and height 1080.


Thanks & Regards,
Pavan Goyal
