I also have a problem corresponding to the absence of 'codecs' property. I have
tested similar pipeline (but without 'h264parse' before mp4dashdemux) in
Chrome, Firefox and Epiphany, and only Epiphany was able to play my stream
(with dash.js library) without 'codecs' property in manifest file.

But I don't have a problem (MEDIA_ERR_DECODE), described in your last message.
My guess is that 'h264parse' is not necessary in your pipeline, but I am not
sure.
