Dependent on language and libraries available you should try making a
HEAD request for each of the URLs you extract. This would return only
the headers of the endpoint, and inside this list you should get the
mime-type of the content. There are a ton of video mime-types but it
should be easy to look for them once you extract the headers.

how will i do that??
I don't think anyone can answer this in detail without knowing what language
are you writing this code in. You should be able to use a regular
expression to extract the URLs and then use the file extension to detect
whether or not it is a direct link to a video file. But if it is a link to
a page that contains a video, you'll have to fetch the page and examine its
links.
There are some URL patterns that you probably can assume point to pages that
contain video, such as YouTube URLs.
