For example, a Mono8 642x482 would have failed to work, as GStreamer expects the stride to be a multiple of 4-bytes, that is 644 bytes in this example, while Pleora doesn't do this alignment. This incurs a copy unfortunately, and there might be a way with memory meta to avoid this, however eventually most elements will need to have the data 4-byte aligned.
