it works fine to last mp4 file and downloaded 3635 files.
i searched 200 138 code but can't find any solutions.
it seems weibo limits feed tabs but i can scroll down further in my browser
i tried with my login cache txt file, other pc's and different ip but same results.
but album or newvideo tap downloads all older files with no problem with login or not.
i tried to download newvideo tabs and album but i think newviedos tab has some omitted videos in old dates
can i have some help for this? thanks.

it seems weibo limits searching through feed tab by since id
by adding page parameter for feed extractor like home extractor and cookie it can go further than since id
i think it works for pc web weibo feeds, thanks for the extractor!
