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.
