The correct way to determine the byte offset at a certain yoffset in a subsampled component is to shift the yoffset by the component's hsub This fixes out-of-bounds memory accesses and visible artefacts, example pipeline with the samples from #802: gst-launch-1.0 compositor name=vmixer sink_1::xpos=1910 sink_1::ypos=1080 ! \ videoconvert ! videorate ! xvimagesink \ filesrc location=VID_20200723_203606.mp4 ! decodebin name=demux1 ! \ queue ! videoflip method=vertical-flip ! vmixer. \ filesrc location=bridgeoverstubbledwater.mp4 ! decodebin name=demux2 ! \ queue ! vmixer.
