MediaRecorder Constrainable Properties question

>From this statement
*The MIME types that can be selected as encodings for recording. The UA should be able to play back any of the MIME types it supports for recording. For example, it should be able to display a video recording in the HTML <img> tag.
I have two questions:
1. What happen if application assign a mimeType or imageHeight/imageWidth that MediaRecorder cannot accept? Throw onerror callback or throw exception?
2. How can application query the mimeTypes list that platform supported?
