Description

Links you can try:
https://www.bilibili.com/bangumi/play/ep324720
https://www.bilibili.com/bangumi/play/ep316830
https://www.bilibili.com/bangumi/play/ep316831
All are playable in browser.
That "Bangumi" URL structure seems to be the problem. Other urls mostly look something like this: https://www.bilibili.com/video/BV1xe411W7Bc?spm_id_from=333.851.b_7265706f7274466972737432.7

most likely this can be fixed by editing "_VALID_URL =" in bilibili extractor to comply with new URL format

bilibili might have changed their URL format for all anime related content—no longer do they use 'bangumi' as a subdomain. Perhaps an update to the parser is needed.
