#8814: Can't open HTTP URL whose file name contains ".."
----------------------------------+--------------------------------------
Reporter: jzlomek | Type: defect
Status: new | Priority: normal
Component: avformat | Version: git-master
Keywords: URL | Blocked By:
Blocking: | Reproduced by developer: 0

----------------------------------+--------------------------------------
Summary of the bug:
FFmpeg can't open HTTP URL whose file name contains ".." as in my example
below.
The problem is that the function trim_double_dot_url does not handle ".."
inside a name correctly. It should eliminate just directory "..".
How to reproduce:
{{{

Equity_Stripping_a_House_in_Divorce_Buy_Whole_Life_Insurance_in_a_Sabbatical_Affirmations_in_Personal_Development_Etc..mp3
?dest-id=152630'
ffmpeg version master (4.3.1)
built on Linux
}}}
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
