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.
MS2_PUBLIC void ms_filter_postpone_task | ( | MSFilter * | f, |
MSFilterFunc | taskfunc | ||
) |
Allow a filter to request the ticker to call him the tick after. The ticker will call the taskfunc prior to all filter's process func.
