Maybe there is better solution to this?There is terminate_on_pause=1 on consumer or you can get a length in frames and check the mlt_consumer_position() or mlt_frame_get_position() within a consumer-frame-show event handler. > But the main problem is that after mlt_factory_close does not clear out > memory on linux.

It is only expected that you call mlt_factory_init() once per process, and you do not need to create-start-stop-close the consumer for each clip. > If I do not close consumer it makes decklink consumer to lag & twich after > some while, but if I reset it every time then it is working fine, except > memory leak of mlt. You are supposed to close the consumer when you are done with it. -- +-DRD-+ ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
