Support final AV1 MP4 MIME type
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.92 Safari/537.36 Steps to reproduce: The final AV1 codec string in the MP4 MIME type is not supported in Firefox. Instead the beta AV1 codec string is used. MediaSource.isTypeSupported('video/mp4; codecs="av01.0.05M.08") MediaSource.isTypeSupported('video/mp4; codecs="av1") Actual results: -> false -> true Expected results: -> true -> false
Indeed, it's actually supposed to accept both strings. Will take a look asap.

While the MP4 parser correctly handles the av01* codec string, it is then converted to a video/av01* mimetype to search for a PDM. The libaom PDM only accepts video/av1, so always produce a video/av1 MIME type from a codecs=av01 string. Alternately, the AOMDecoder could be made to accept video/av01*, but this patch matches what VPXDecoder does.
