Controlling size of video (seems browser dependent)

Hi all … what’s the recommended way to set the size (width x height) for published/subscribed video streams? We’ve been experimenting with setting the “resolution” property in “initPublisher” (as outlined in Cheatsheet: Publish/Unpublish a stream) but this seems to be very browser dependent, e.g. Chrome seems to work fine but not so with Firefox. Should we instead be setting the “videodimensions” property in the Connection object (Reference Documentation/REST API)?

Thanks!
