com.avpkit.core.io.URLProtocolManager

public class URLProtocolManager
extends java.lang.Object

This class manages URL protocols that we have handlers for. It is used (and called from) the Native code that integrates with FFMPEG. To register a handler you would use the singleton manager as follows:

  URLProtocolManager mgr = URLProtocolManager.getManager();
  mgr.registerFactory("myprotocol", myProtocolHandlerFactory);

getManager

public static URLProtocolManager getManager()

Register a new factory for IURLProtocolHandlers for a given protocol.

FFMPEG is very picky; protocols must be only alpha characters (no numbers).

Parameters:

protocol - The protocol, without colon, this factory is to be used for.

factory - The factory for the manager to use whenever a handler is requested for a registered protocol; null means disable handling for this factory.

Returns:

The factory that was previously used for that protocol (or null if none).

                                      int flags)
