Customize segments

[IacoSimoncini]

is it possible to have segments that have a fixed time duration?

@IacoSimoncini This is behaviour that is used. All segments have a fixed duration.

@djvergad I thought that every segment has a fixed length of 100 frames. So that the length was fixed in dimension, not in time. In the end can you tell me where the time duration of the segment is set in the library? Thanks for your answer.

@IacoSimoncini It is defined in

dash/model/mpeg-header.h

Line 37 in 2fb682d

#define MPEG_TIME_BETWEEN_FRAMES 20 // Miliseconds or 50 fps

There are 100 frames per segment, and time between consecutive frames is 20 ms (50fps). The bitrate is adapted by changing the size in bytes of the frames. The time between frames is constant.
