Add support for m3u8 with temp CDN ts inside

[mglants]

I have a multicast provider so his m3u looks like

#EXTM3U
#EXTINF:-1 group-title="Общие" tvg-rec="7" timeshift="7",Первый канал HD
http://myott.tv/stream/****/131.m3u8
#EXTINF:-1 group-title="Общие" tvg-rec="7" timeshift="7",Россия HD
http://myott.tv/stream/****/137.m3u8

As this filles coresponds to

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:2270
#EXT-X-TARGETDURATION:10
#EXTINF:9.480,

I cant extract those tokens as they are temporal

I have a similar situation that where the .m3u8 file also references to dynamic files (I think it is called "nested" m3u in the wiki). For me it works when enabling FFMPEG transcoding.
