Simulating camera behaviour with a mock script

This package also offers a mock command, which upon calling will start to simulate a phantom camera. It will behave just like a phantom, except there doesnt need to be a ethernet cable, as it will be running on the local IP 127.0.0.1 using the standard port 7115 for the control connection.

To start the mock service simply use the “ph-mock” command.

ph-mock

The mock is mostly designed to test all the other commands within this package even without immediate access to a real camera itself. For that just open two terminals and start the mock with the command above and run the other commands in the second terminal.

An example

To view the main configuration of the camera and then grab a single frame just start up the mock as follows:

# Terminal 1
ph-mock

Then use the “ph-getall” command to display a table containing the most important attribute values and the “ph-img” command to view an image

# Terminal 2
ph-getall 127.0.0.1 ;
ph-img --format=P8 127.0.0.1

Unsupported features

The mock is still far from being a perfect emulation of a real camera, as it lacks a few features:

• Upon receiving possibly incorrect input, the returned error message is not reflective of what a real camera may respond. In some cases there may not even be an error message at all, but instead a crash of the mock script
• Some attributes do not have an internal default value yet. Issuing a “get” command can result in the mock crashing
• Setting different values to the attributes has no effect
