Library rtsp

This Real Time Streaming Protocol (RTSP) library implements only a minimal subset of the protocol needed by the current scripts.

Author:

• Patrik Karlsson <patrik@cqure.net> The library contains the following classes: * <code>Request</code> ** This class contains the functions needed to create the RTSP request * <code>Response</code> ** This class contains the functions needed to parse the RTSP response * <code>Client</code> ** This class contains the RTSP client, a class responsible for sending and receiving requests and responses to/from the server * <code>Helper</code> ** This class serves as the main interface for script writers The following sample code shows how to use the library: <code> local helper = rtsp.Helper:new(host, port) local status = helper:connect() local response status, response = helper:describe(url) helper:close() </code>
