Onvif Command Support

Each of the following Onvif Web services has its own directory:

Inside each directory there is:

  • types.go: contains the struct definitions for each onvif command and response
  • function.go: contains the auto-generated types that implement the Function interface providing Request() and Response() type mappings.

At the root level there is:

  • names.go: contains the auto-generated constant names of all the commands
  • mappings.go: contains the auto-generated mappings for each Onvif WebService from function name to function datatype

Adding support for additional commands

Note: Currently, the python script looks for types that end with Response and work backwards from there. This is to prevent creating commands for every struct type defined there, and only the ones that are actually commands. It also skips any types ending with FaultResponse, as there typically are no Fault commands, only responses.

For the respective web service the command belongs to, add the command and response struct definitions into <web-service-name>/types.go, and then run:

python3 python/gen_commands.py

Note: You can also typically run the generator within your IDE thanks to the //go:generate lines towards the top of the types.go files.
