which has mp4 chunks @ following bit rates:13086,180972,222651,etc want develop algorithm calculate network bandwidth , map mpr chunks of particular mpd i.e @ bandwidth how should take chunk playing.is there paper,sample code can use starting point.i referring mpegdash open source libdash implementation not able find algorithm.

regards mayank

in libdash sampleplayer can find the iadaptationlogic interface, can use implement own logic, e.g., takes bandwidth measurements account. example adaptation logic uses minimum quality available named alwayslowestadaptatiologic. rate based sample adaptation logic available inside of vlc. libdash source inspired vlc dash module has been developed before. if want evaluate performance of adaptation logic can start mpeg-dash dataset paper based on content referring. additionally, compare industry solutions such bitdash or open source implementations such dash.js. if want generate own content experiment use open source toolchain ffmpeg/mp4box or cloud based services such bitcodin.
