I'm not sure if older version of videoparse support downstream caps filter. Try and use the properties instead, like this (note the properties will take small caps): .. ! videoparse format=rgb width=3456 height=2592 ! ... In any case, 24bit RGB (not padded) is likely not supported by xvimagesink. XV extension usually only allow YUV formats. ximagesink may support padded RGB, like xRGB or BGRx. With the benifit that the image size of xRGB/BGRx is the same as packed YVYU.
