Description

Now BiliBili redirects the link http://bangumi.bilibili.com/anime/1869/play#40062 (which is a test in the bilibili extractor) to https://www.bilibili.com/bangumi/play/ss1869#40062. A new solution is needed ?

there month passed...

Any updates?

I make a pr #25308 now add support for url like https://www.bilibili.com/bangumi/media/md3814
and https://www.bilibili.com/bangumi/play/ep86635

[tinytangent]

https://www.bilibili.com/bangumi/play/ep and https://www.bilibili.com/bangumi/play/ss
are different kinds of address, and new anime seems to have all migrated to https://www.bilibili.com/bangumi/play/ss.

Not really familiar with reverse engineering those web video protocols but seems https://www.bilibili.com/bangumi/play/ss use a different protocol from https://www.bilibili.com/bangumi/play/ep. Because after reading the code of #25308 I noticed that it uses
https://api.bilibili.com/pgc/view/web/season?ep_id= to extract video info, but the ep_id is not the number after ss for addresses starting with https://www.bilibili.com/bangumi/play/ss.

Any ideas?
@ywwzwb @AtlasChuen @thanksshu

I also wonder why #25308 is still not merged...neither does #24322

[tinytangent]

No...seems the protocol is not different, just the URL...After reading the API result I noticed something interesting. ss addresses might have a corresponsding ep address, for example:
https://www.bilibili.com/bangumi/play/ss3814
https://www.bilibili.com/bangumi/play/ep86635

It might be just the different API interface.

https://api.bilibili.com/pgc/view/web/season?season_id=3814
https://api.bilibili.com/pgc/view/web/season?ep_id=86635

Could anyone merge some of these PRs?
