But Maybe let videoaggregator decide output size is more reasonable. When
sinkcaps has changed, but glvideomixer output caps cannot been reconfigured
even no capsfilter downstream. It's more import to repest the calculated best
width and height. What's your opinion? Or do you have some solution to support
both kind of case
