After recently changing .pylintrc (see [1]) we discovered that the presubmit check always checks all the python files when just one python file gets updated. This CL moves all these files one step closer to what the linter wants. Autogenerated with: # Added all the files under pylint control to ~/Desktop/to-reformat cat ~/Desktop/to-reformat | xargs sed -i '1i\\' git cl format --python --full This is part 1 out of 2. The second part will fix function names and will not be automated.

"""Checks if a virtual webcam is running and starts it if not.
|
|
|
|
Returns a non-zero return code if the webcam could not be started.
|
|
|
|
Prerequisites:
|
|
* The Python interpreter must have the psutil package installed.
|
|
* Windows: a scheduled task named 'ManyCam' must exist and be configured to
|
|
launch ManyCam preconfigured to auto-play the test clip.
|
|
* Mac: ManyCam must be installed in the default location and be preconfigured
|
|
to auto-play the test clip.
|
|
* Linux: Not implemented
|
|
|
|
NOTICE: When running this script as a buildbot step, make sure to set
|
|
usePTY=False for the build step when adding it, or the subprocess will die as
|
|
soon the step has executed.
|
|
|
|
If any command line arguments are passed to the script, it is executed as a
|
|
command in a subprocess.
