Create MPEG-DASH Initialization segment
I am looking to convert between HLS and MPEG Dash. I do not access to the original fully concatenated video file, only the individual HLS segments. In doing this transformation to MPEG Dash I need to supply an initialziation segment for the Dash manifest .mpd file. My questions are: What is the structure of a Dash video initialization segment? How can I generate/create one without the need for the original full file? Perhaps a solution would involve getting MP4Box to convert the '.ts' HLS segments to Dash '.m4s' segments which are self initializing, but I am unsure how to go about this this?
