MPEG-DASH is a steaming technology that splits up the media into small chunks, making it easier to cope with changing streaming circumstanes. However it does mean that there is no single streaming URL. So Volumio at its present state will not be able to stream MPEG-DASH streams.
The BBC, amongst other organisations are all moving towards MPEG-DASH. This could mean the end for mainstream Internet Radio. Unless we develop some way of streaming MPEG-DASH. Or incorporating a mobile phone style web browser in Volumio, so we could stream directly from the streamers website.
