>>> # Do something awesome!
>>> c.stop()

License & Repository

Castro was created by Jason Huggins. It is licensed under the GPLv2, since it is a derivative work of pyvnc2swf, which is also licensed under the GPLv2.

Castro has a git respository at github.com.

Summary

Castro is a minor fork of pyvnc2swf, allowing one to use pyvnc2swf as a regular Python library, instead of a Tk GUI application or command line utility.

The specific improvement Castro brings to pyvnc2swf is the ability to start and stop recording programmatically via a simple Python API. Castro uses a file-based IPC to tell pyvnc2swf when to stop recording.

Ordinarily, pyvnc2swf’s command line utility, vnc2swf.py, expects users to stop recording by manually typing “Control-C”, sending a KeyboardInterrupt and allowing the process to exit cleanly. On Linux, emulating KeyboardInterrupt is simple enough to do by sending a SIGINT signal. But this does not work cross- platform, specifically on Windows. And a big reason for using pyvnc2swf is its ability to record vnc video on any platform from any platform.
