Perhaps you would explain in detail what isn't color correct ? To debug this, you probably want to inspect the caps and the colorimetry negotiated between each element (use -v in gst-launch-1.0). It's quite possible that the decoder is ignoring upstream colors and get badly hinted by the driver, or that kmssink is pnot passing colorimetry to the driver. > > Thanks
