Add SegmentBaseController
Created by: nicosang
Hi,
this PR has to create a new static class, named SegmentBaseController, that has to send request to get init or media segments list in SegmentBase use case.
The idea is to isolate this part of code in order to have in SegmentController only functions to get segment (with time or id) without any network access. In SegmentBase use case, the SegmentController will trigger an event that will be catched by SegmentBaseController to send requests.
In ThumbnailTracks, SegmentBaseLoader was used, I updated this part of code but no tests have been made because the sample stream is not available. :-( Nico
