BiliBili extractor downloads only a part ot the video

[Rudloff]

When I try to download this video, it downloads only the first 6 minutes.

Yes, it will only download the first part of the video. As is implemented in the code:

    lq_durl = lq_doc.find('./durl')
    formats = [{
        'format_id': 'lq',
        'quality': 1,
        'url': lq_durl.find('./url').text,
        'filesize': int_or_none(
            lq_durl.find('./size'), get_attr='text'),
    }]

lq_durl.find('./url').text uses find method, and thus only the first part of the video will be reported from extractor. I agree this extractor should be enhanced as most of the video on bilibili is splited into parts and meanwhile the playlist is not handled correctly as well.

Thanks @Rudloff for the report and @wanglongqi for digging the problem. I've fixed bilibili extractor and in the next version of youtube-dl multipart videos can be downloaded correctly. @Rudloff The video you provide is not accessible for me, so I use http://www.bilibili.com/video/av1041170/ as the test case.

This is still an issue for me on version 2018.04.16, though it looks like the cause is slightly different. It looks like it tries to re-download the same video part 6 times, and 5 of them it ignores saying "has already been downloaded".
