  • FFmpeg dash manifest '-window_size'

    14 novembre 2018, par edwinbradford

    In the FFmpeg DASH documentation I don’t understand the purpose of -window_size which is explained as :

    Set the maximum number of segments kept in the manifest.

    If my video is 30 seconds long, the GOP size is 4 seconds and the segment length is 4 seconds, what is the meaning and purpose of a parameter to control the maximum number of segments kept in the manifest, when does this parameter need to be used and how do you determine valid values ?

    I’m guessing that the stream is being loaded into memory and the number of segments in the manifest controls how much is kept in memory at one time but it’s just a wild guess and I can’t find any further explanation.

    I am not live streaming in case it’s relevant.
