some questions about the generated multi-video size #103

hi~In the mutil video experiments,you generate lots of videos which has various avaliable bitrate sets.You randomize the segment size by adding noise to the standard size of the corresponding bitrate.The standard size is defined as MEAN_VIDEO_SIZE = [0,1, 0.15, 0.38, 0.6, 0.93, 1.43, 2.15, 3.25, 4.5,6].Could you tell me how you calculated the standard size and whether the segment only includes video without audio?Thanks for your reply.

IIRC, I get the mean video size from an actual video with this many bitrate encoding levels ((we searched for this kind of videos from dash industry forum). The segment includes audio I believe (it will be similar to these video files for example https://github.com/hongzimao/pensieve/blob/master/video_server/video1/1.m4s).
