[FFmpeg-devel] [PATCH] fix: the "delete-segment" flag did not work properly

[develop at focusware.nl]

From: Boris Nagels <develop at focusware.nl>

Implementation in commit 97b65f6. The set length of the list was populated twice (e.g. setting the list-size to 10, creates a list of approx. 20 files). Now calculation works on the theoretical playlist length compensated for the segment lengths that are currently in the playlist.
