Interrupt: Stopping pipeline ... ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline ... It seems like glcolorbalanc is causing decodebin not to link with vaapih264enc since it is the only difference between above pipeline. I am new to gstreamer and Can any one tell me what is wrong with 2nd pipeline and why linking is failing ? </div>
