With StreamEye command line tool, the complex analysis operations become as fast and easy as a few lines of commands.

Using this tool you'll be able to: 

  • Analyze the whole array of video files automatically;
  • Address specific and complex challenges with a few lines of commands;
  • Retrieve submitted results as a text file in CSV format for easy viewing in Excel;
  • Customize a sequence of commands to perform your specific tasks;
  • Accelerate and automate your regular tasks;
  • Get access to most of StreamEye functionality and resources through StreamEye Console.

How to use StreamEye Command line tool:

To streamline automatic analysis of several files the following rules are introduced. They reassign input and output parameters for configuration files.

Get to the command prompt by clicking Start->Run and type 'cmd'. Then enter the command to start the application first and proceed with the command line options. In general, the syntax is as follows:

SEyeConsole.exe <config path> <options>

Note: you should not relocate the <product> console without all the other applications of the product contained in the installation pack, otherwise the console application will not start.


 

Notes on the Command line rules

1. Parameters with default value are not required and can be omitted.

2. Rules for input and output file names:

  • parameter /in:<file path> in the command line overwrites the value of the tag <input> in the configuration file;
  • parameter /out:<file path> in the command line overwrites the value of the tag <output> in the configuration file;
  • if <output> tag is missing (or not specified), output file names are formed from input file names plus suffix (if the latter is specified);
  • if output file for a tag/section is not specified, the output file name for the tag/section is formed from the name specified in the <output/> tag plus suffix depeding on the name of the tag/section, e.g. ".message.csv", ".header.csv", etc.
