Title: Need help with external process
Post by: nikel on October 29, 2020, 11:06:39 am

Hello, I'm trying to run a program in command line on Windows. This works fine:

Code: Pascal  [Select][+][-]

1. if RunCommand('ffprobe',['-loglevel error -show_entries format_tags=' + Request +' -of default=noprint_wrappers=1:nokey=1 ' + '"' + Path + '"'], Str) then  begin

But this doesn't set any value:

Code: Pascal  [Select][+][-]

1. if RunCommand('ffprobe',['"' + Path + '"'], Str) then begin

How can I execute an external command and get the output on Windows?

- No quoting
- pass multiple parameters as a list
   so

RunCommand('ffprobe',['-loglevel','error','-show_entries format',.....

etc
