[bilibili] youtube-dl shows video formats inconsistently

[xczheng]

Now sure if this is a youtube-dl problem, or server side problem, but it shows the formats inconsistently. Sometimes it has format "1" and sometimes it doesn't.

Could you run youtube-dl --write-pages -v -F "https://www.bilibili.com/video/av14782039/" and upload *.dump files when there are 2 formats? I never get more than 1 format for this video.

I'm getting two formats:

{
    "from": "local",
    "result": "suee",
    "quality": 16,
    "format": "mp4",
    "timelength": 2909909,
    "accept_format": "mp4",
    "accept_quality": [1],
    "seek_param": "start",
    "seek_type": "second",
    "durl": [{
        "order": 1,
        "length": 2909909,
        "size": 385106987,
        "url": "http://tx.acgvideo.com/28/98/24089828/24089828-1-16.mp4?txTime=1515433518&platform=pc&txSecret=60941bdc9fb59243cbb5be9054cb1252&oi=3306640703&rate=240000&hfb=b99ffc3c5c68f00a33123bb25f882d5b",
        "backup_url": ["http://ws.acgvideo.com/8/60/24089828-1.mp4?wsTime=1515433518&platform=pc&wsSecret2=8499ba4c14b6240dac2f9951c972b58e&oi=3306640703&rate=224"]
    }],
    "hit_ssd_sid": []
}

@yan12125 i don't see a problem here, it depend on whether bilibili return a backup_url or not.

[yan12125]

it depend on whether bilibili return a backup_url or not.

Thanks. You're right.
