Maybe try reversing you capture width and height. <div class="gmail_quote">On Tue, Jan 22, 2013 at 9:52 PM, Guetcho Guetchev <<a href="mailto:getcho.getchev@gmail.com" target="_blank">getcho.getchev@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Dear Gstreamers, I have the following pipeline (Gstreamer 1.0.5): appsrc caps=video/x-raw,format=NV12,width=480,height=640,framerate=20 ! videconvert ! capsfilter caps=video/x-raw,format=RGB ! appsink A sample of the resulting image can be observed here: <a href="http://imageshack.us/a/img802/5821/image068.png" target="_blank">http://imageshack.us/a/img802/5821/image068.png</a> I am pretty sure the input image is correct, because it comes from an iPad camera. For the more curious the native pixel format is a bi-planar component Y'CbCr 8-bit 4:2:0, video-range (luma=[16,235] chroma=[16,240]). The question is: what might cause the left border disturbance? Also, please, notice the upper left corner is totally garbled. Any ideas?
