IMO, the problem is that you're modifying the default behavior even
though an option already exists to let you specify the amount of segment
files to keep around. This might be suitable in your use-case, but what
if I (or someone else) wanted to keep all the segment files for archival
purposes, but not list them in the m3u8; with your patch this no longer
If you were to write a new patch that made hls_wrap default to
hls_list_size instead of the default 0, it would no longer impose
artificial limits on users. At that point, the inclusion of the patch
would depend on the opinion of the hls maintainer and the other FFmpeg
maintainers with opinions on the matter.
