The documentation for the webm_dash_manifest muxer mentions the time_shift_buffer_depth option, defined as "Smallest time (in seconds) shifting buffer for which any Representation is guaranteed to be available. "
What's the equivalent option/setting for the same in the dash muxer (,if implemented) ?
-window_size <num_segments> multiplied by the last segment duration appears to set timeShiftBufferDepth, when a SegmentTemplate is in use.
