Avoiding Multiple matches in regex

Question

This is the html code:

 [{file: "http://srv74.vidzi.tv/hls2/jjuqjoa4ki2qedz7nlhbttjfjz62mrdkpxryo6zgr,llnmsfgxyea6jqrfama,bb5msfgxyencp5qkgqa,.urlset/master.m3u8"},{file: "http://srv74.vidzi.tv/jjuqjoa4ki2qedz7nlhbttjfjz62mrdkpxryo6zgrbb5msfgxyencp5qkgqa/v.mp4"}]

My intention is to extract the link ending with v.mp4

My regex is as follows:

(http://srv74.vidzi.tv/.+?/v.mp4)

However, I get both urls as matches in my regex How do I avoid multiple matches?

I am using pythex

Answer 1

You can't get around using a common start position unless you exclude
it when using the dot . character.

This is the more reliable way.
Doing this you don't have to worry about valid url chars or
whether there are possibly other separators.

(http://srv74\\.vidzi\\.tv/(?:(?!srv74\\.vidzi\\.tv).)+?/v\\.mp4)

 (                             # (1 start)
      http://srv74\.vidzi\.tv/
      (?:
           (?! srv74\.vidzi\.tv )        # Don't let this be before mp4
           . 
      )+?
      /v \. mp4 
 )                             # (1 end)
