HI, I have an app, which send samples of video to gstreamer. when the play back starts, gstreamer get the window size automatically based on the source. But I want to control it. I tried videoscale = gst_element_factory_make ("videoscale", "video_scale"); g_object_set (G_OBJECT (videoscale), "width", 500, NULL); g_object_set (G_OBJECT (videoscale), "height", 500, NULL); but I am getting <ul><li>object class 'GstVideoScale' has not property named 'width'</li> <li>object class 'GstVideoScale' has not property named 'height'</li></ul>Need some help here. how do i set the width and height correctly, and is there any way to change the dimensions while the video is playing. Thanks, Girish
