adaptive-bitrate

. I am trying to understand how mpd file plays and i am referring to the following data set: http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/Valkaama/MPDs/Valkaama_1s_act_isoffmain_DIS_23009_1_v_2_1c2_2011_08_30.mpd In mpd file format there is segment base consists of mp4 chunk and within it has chunk list with extension .m4s.I downloaded mpd file using : http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/Valkaama/valkaama_1s/valkaama_1s_50kbit/valkaama_50kbit_dash.mp4 and m4s chunk by following link: http://www-itec.uni-klu.ac.at/ftp/datasets/mmsys12/Valkaama/valkaama_1s/valkaama_1s_50kbit

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?

I am looking for good and simple example/explanation how to implement ExoPlayer for HLS Adaptive streaming. I am a newbie and do not have experience and knowledge so I can figure how to do this from code example on git. There are too many 'moving parts' so beginner can understand and reuse it in own projects. Can somebody help me to learn and understand how to use/implement ExoPlayer in order to achieve this functionality? Thanks! Vicky The easiest way to get started using ExoPlayer is to add it as a gradle dependency. You need to make sure you have the jcenter repository included in the build
