I get video-capture-supported-caps when camerabin is in PLAYING state. The
native caps should be the first one structure in caps? I will check if has bug.

wrappercamerabinsrc will use videoscale to do digital zooming. So how to set
camera output caps? If native camera support several output resolution, do user
need set camera source and capfilter bin to wrappercamerabinsrc to select
native camera output resolution? Or wrappercamerabinsrc need add camera output
capsfilter property?
I have tried set preview and video capsfilter on wrappercamerabinsrc output
pad. But I met renegotiation error as zoom_capsfilter will be fixed to the
default caps and will fail if I set caps different with the default caps.
