Should I be doing something manually?
You should add this in your consumer thread after your call to output(). mlt_events_fire( properties, "consumer-frame-show", frame, NULL ); > I see the sdl consumer does some queuing of frames, and waits until > the proper time to show it. Should I be doing something similar? To The consumer controls the timing. That is the audio clock in something like the sdl consumer, but decklink and sdi consumers use their SDK/driver for timing. In your use case, you probably do need some kind of a timer. > me, it'd make more sense to request the frames as needed, because > there's some filters that will depend on real-time data, plus the > input right now is a file, but it could very well be a live stream, or > whatever, so I'm not sure what I'm doing wrong, but the sdl consumer > is not an exact model for what I want to do. The other process's producer that reads the shm could use some IPC or signaling to this consumer, but I do not have a specific recommendation here. -- +-DRD-+ ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Mlt-devel mailing list Mlt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mlt-devel
