Description
Summary of the bug:
One of the params is -start_number 1 for running HLS output like this:
C:\ffmpeg\ffmpeg.exe -re -i "rtmp://bar/foo.flv" -y -c:v copy -c:a copy -hls_time 6 -hls_list_size 5 -hls_wrap 30 -start_number 1 "C:\Tools\Foo\stream.m3u8"
But if your -start_number 100000
It will still start with 1

Please also consider to read again the following sentence from the specification:
A media URI is not required to contain its sequence number.

Confirm the bug. There is some confusion between URI sequence number (which may be cyclic) and the EXT-X-MEDIA-SEQUENCE number specified in the M3U8, which are two distinct entities.

Documentation should be clarified since:
commit f6707f0689e025e39f17c1e452f4033743079801
Author: Stefano Sabatini <stefasab@gmail.com>
Date: Thu Jan 2 00:30:37 2014 +0100
doc/muxers/hls: extend documentation
In particular, reference segment muxer and clarify difference between
segment filename number and playlist sequence number.
Should fix trac ticket #2601.



This works fine here, if you want to reopen this ticket, please provide the command line that allows to reproduce the problem together with the complete, uncut console output and attach the m3u8 file.
