[FFmpeg-devel] [PATCH] libavformat/segment: change segment_list_size behavior to match hls_list_size behavior.

[Simon Thelen]

Make the segment muxer keep segment_list_size segments instead of
segment_list_size + 1 segments. This patch also changes the
documentation for segment_list_size to reduce possible confusion over
how many segments are kept.
