	Retrieves statistics for running filters. Returns a list of MSFilterStats.
MS2_PUBLIC void	ms_filter_log_statistics (void)
	Logs runtime statistics for running filters.

Detailed Description

mediastreamer2 msfilter.h include file

This file provide the API needed to create, link, unlink, find and destroy filter.

It also provides definitions if you wish to implement your own filters.
