[FFmpeg-user] Append live to existing video

[Louis Letourneau]

> What about the option "-hls_flags append_list"

Well what do you know, change request from you on Aug. 11, 2016, what a
terrific idea.
My version doesn't have it, I'll compile a new one and try it as soon as I
can.

Thanks a lot Liu! That sounds exactly like what I need.
