So I have now installed the latest xidel binary on my Ubuntu Server 20.04.4
where all downloads happen:

$ xidel --version
Xidel 0.9.9
(20220131.8335.4e6fcea4d02e)

This URL is used in your examples, which all work fine now that I understand
what is going on.
But this might not be the correct such URL for the 2308 video?
See below

I have also gone ove each of your descriptive commands one by one and verified
how they work on the 2308 URL.
It seems like I get responses similar to but different from the 2565 URL for
early parts.

But when I run this command I get a response, which when used for download gets
a completely different channel:

$ xidel -s "http://www.freeintertv.com/view/id-2308" -e
'x:request({"post":request-combine((),{"chname":string-to-base64Binary(extract(//meta[@property="og:image"]/@content,"([a-z_]+)\.jpg",1)),"ch":"http://www.freeintertv.com/externals/tv-russia/smotret-tv3-online","html5":"11"})/substring(url,2),"url":"http://www.freeintertv.com/myAjax/get_item_m3u8/"})/extract(raw,"http.+m3u8")'

output is this m3u8:
http://livedoc.cgtn.com/500d/prog_index.m3u8

It can be used with my downloader but when I record and then view the content it
shows a completely different channel...


I don't know from where this URL in the command came from (you say you can see
it...):
http://www.freeintertv.com/externals/tv-russia/smotret-tv3-online

But it is for the 2565 video...
Maybe another is needed for 2308?
