Apart from emitting tags, it would also be useful to let an image metadata
parser change the caps. Specifically, width and height are always present.

A use case for this is multiplexing of motion JPEG. The source of the JPEG data
may not provide width and height properties in the caps, but multiplexers like
avimux and matroskamux demand these properties on their source pads:
souphttpsrc location="http://webcam/mjpeg" do-timestamp=true ! multipartdemux !
metadataparse ! matroskamux ! filesink location="webcam.mkv"
