default hls clean up time?

[goofyseeker311]

there is no mention or setting for the hls clean up time.
its something "soon", definitely longer than 2 minutes and not just after stream end.
so far at least 4 minutes from the end of a stream, still the .m3u8 file is there.

it does not even clean up the .ts files when starting a new stream.
the .m3u8 file clean up is faster than any of the .ts files.

I think the .ts files not being clean up fully is because of the playlist length time, for example 6 minutes of previous footage.
might be by design.

side note: even if playlist time is set to 240s, the visible stream video buffer length in browser is 6-7min (360-420s).
full clean-up sometimes happens if nginx is restarted (service nginx restart), but that should not be required or forced.

I used exec_record_done directive to clean up the .m3u8 file after stream end, when the clean up was not quick enough.
