def load_m3u8(src, url=None, headers=None):
    # is playlist raw text, a path to a file, or a url?
    if src.upper().startswith('#EXTM3U'):
        m3u8_obj = m3u8.loads(src)
        m3u8_obj.playlist_url = url
        m3u8_obj.base_uri = _parsed_url(url)
    elif os.path.exists(src):
        m3u8_obj = m3u8.load(src)
        m3u8_obj.playlist_url = url
        m3u8_obj.base_uri = _parsed_url(url)
    else:

        m3u8_obj.playlist_url = src
    return m3u8_obj
