m3u8downloader is a tool to download video at a m3u8 link. `HTTP Live
Streaming (HLS)`_ is becoming popular. m3u8 playlist is used by HLS to serve
video fragments of different quality to different clients. This tool supports
HLS master playlist and media playlist. If master playlist is given, it
selects the highest resolution automatically. HLS fragment encryption is
supported. Resume from partial download is supported, just rerun the same
command to continue.
ffmpeg is used to convert the downloaded fragments into final mp4 video file.

Limitations
-------------
This tool only parses minimum m3u8 extensions for selecting media playlist
from master playlist, downloading key and fragments from media playlist. If a
m3u8 file doesn't download correctly, it's probably some new extension was
added to the HLS spec which this tool isn't aware of.
* v0.8.7
- bugfix: do not rewrite KEY URI if it is already a local file path.
* v0.8.6
- fix a regression in v0.8.4. the v0.8.4 release should be avoided. Either
use v0.8.3 or v0.8.6+
* v0.8.4
- minor bugfix: still try rewrite path when using m3u8 file from cache.
when rewrite path in m3u8 file, do not rewrite if path has already been
rewritten before. This is a minor change, it only fix things when process
is killed when .m3u8 file is downloaded but path in it has not been
rewritten yet.

windows platform.
