With your patch, if the property list of a stream without filter.apply set is changed, the stream will still falsely be moved to the master sink. I believe the right way to solve it would be to set the filter.apply property and module_name when the sink_input_put hook is called and the sink is a filter sink. I also wonder why you use an enumeration when you only use one of the values. A boolean is_put argument to process() would do. Regards Georg
