This page says:

您播放的视频出错了！

(There's something wrong in the video you played!)

Can you watch this video in browsers?

[dstftw]

Plays fine.

[yan12125]

Thanks dstftw. They serve plain HTTP m3u8 streams on HTTPS websites, and I've configured Firefox to blocks such requests in the past. Worked fine with security.mixed_content.block_display_content set to false.

Single video: https://v.douyu.com/show/rjNBdvnVXNzvE2yw
P/S I am told that the video is separated into 10sec clip which makes the download process very hard, therefore in order to download from this website, one has to download a playlist and then merge the files together. Does the website behaves like this and is it possible to add support to this site in terms of coding?

An easier way is to obtain the link directly using Internet Explorer agent, using other browser such as Chrome/Firefox to obtain the link will return an error upon download.

Sorry for the late response. Douyu shows will be supported in the next version.
