Any Bilibili videos more than 10mins are downloaded as multiple files

[ZelunZhang]

Hi,
I am using the latest version of youtube-dl.
However, i noticed that any videos that are more than 10mins long on Bilibili is downloaded as multiple filed.
Tried the following options:
--buffer-size 1G
--http-chunk-size 1G

Still no luck.
Could you please have a look and let me know how to download long Bilibili videos to a single video file.

Command i used:
youtube-dl -f 1 -o "%(title)s-%(id)s.%(ext)s" --write-description https://www.bilibili.com/video/av10860038

You can't download as a single file cause it's not served as single file.

Hi,
it looks to me that the origin website is serving the video as one file. As in the UI download website http://www.urlgot.com/en_US/, when the url is parsed, it shows it as one single file, like the following.

And the file can be downloaded as a single file.

Could you please have another look of the issue?

These are not original files. All linked to d*.urlgot.com.

Why couldn't youtube-dl automaticaly combine the parts using ffmpeg if present? Or at least have a flag for it.
