Just making sure this patch hasn't been overlooked. To better explain the existing issue - the value of 'pls->first_seq_no' comes from the 'startNumber' attribute of the 'SegmentTemplate' element. The 'pls->timelines' array represents the elements within the 'SegmentTimeline' element. So

[FFmpeg-devel] [PATCH] dashdec: Fix segfault on decoding segment timeline

If first_seq_no is not within the bounds of timelines then a segfault will occur. This patch removes the use of first_seq_no within the timelines array It also adds first_seq_no to the value returned by calc_next_seg_no_from_timelines (which allows for different values of 'startNumber')
