    Usage:
    python biligrab.py (-h) (-a) (-p) (-s) (-c) (-d) (-v) (-l) (-e) (-p) (-m) (-n) (-u)
    -h: Default: None
        Print this usage file.
        a
    -a: Default: None
        The av number.
        If not set, Biligrab will use the falloff interact mode.
        Support "~", "," and mix use.
        Examples:
            Input        Output
              1           [1]
             1,2         [1, 2]
             1~3        [1, 2, 3]
            1,2~3       [1, 2, 3]
    -p: Default: 0
        The part number.
        Able to use the same syntax as "-a".
        If set to 0, Biligrab will download all the avalable parts in the video.
    -s: Default: 0
    Source to download.
    0: The original API source, can be Letv backup,
       and can failed if the original video is not avalable(e.g., deleted)
    1: The CDN API source, "oversea accelerate".
       Can be MINICDN backup in Mainland China or oversea.
       Good to bypass some bangumi's limit.
    2: Force to use the original source.
       Use Flvcd to parase the video, but would fail if
       1) The original source DNE, e.g., some old videos
       2) The original source is Letvcloud itself.
       3) Other unknown reason(s) that stops Flvcd from parasing the video.
    For any video that failed to parse, Biligrab will try to use Flvcd.
    (Mainly for oversea users regarding to copyright-restricted bangumies.)
    If the API is blocked, Biligrab would fake the UA.
    3: (Not stable) Use the HTML5 API.
       This works for downloading some cached Letvcloud videos, but is slow, and would fail for no reason sometimes.
    4: Use Flvcd.
       Good to fight with oversea and copyright restriction, but not working with iQiyi.
    -c: Default: ./bilicookies
    The path of cookies.
    Use cookies to visit member-only videos.
    -d: Default: None
    Set the desired download software.
    Biligrab supports aria2c(16 threads), axel(20 threads), wget and curl by far.
    If not set, Biligrab will detect an avalable one;
    If none of those is avalable, Biligrab will quit.
    For more software support, please open an issue at https://github.com/cnbeining/Biligrab/issues/
    -v: Default:None
    Set the desired download software.
    Biligrab supports ffmpeg by far.
    If not set, Biligrab will detect an avalable one;
    If none of those is avalable, Biligrab will quit.
    For more software support, please open an issue at https://github.com/cnbeining/Biligrab/issues/
    Make sure you include a *working* command line example of this software!
    -l: Default: 0
    Dump the log of the output for better debugging.
    -e: Default: 1
    Export Danmaku to ASS file.
    Fulfilled with danmaku2ass(https://github.com/m13253/danmaku2ass/tree/py2),
    Author: @m13253, GPLv3 License.
    *For issue with this function, if you think the problem lies on the danmaku2ass side,
    please open the issue at both projects.*
    If set to 1 or 2, Biligrab will use Danmaku2ass's py2 branch.
    If set to 3, Biligrab will use Danmaku2ass's master branch, which would require
    a python3 callable via 'python3'.
    If python3 not callable or danmaku2ass2/3 DNE, Biligrab will ask for action.
    -p: Default: None
    Set the probe software.
    Biligrab supports Mediainfo and FFprobe.
    If not set, Biligrab will detect an avalable one;
    If none of those is avalable, Biligrab will quit.
    For more software support, please open an issue at https://github.com/cnbeining/Biligrab/issues/
    Make sure you include a *working* command line example of this software!
    -m: Default: 0
    Only download the danmaku.
    -n: Default: 0
    Slient Mode.
    Biligrab will not ask any question.
    -u: Default: 0
    Export video link to .m3u file, which can be used with MPlayer, mpc, VLC, etc.
    Biligrab will export a m3u8 instead of downloading any video(s).
    Cannot use sources other than 0 or 1.
