So if you need to start recording from a proper moment you see on decklink output, you need to unpause it. but it not so simple because if you set speed 0.0 to producer, it still send a frames to avformat consumer (moreover it exit encoding thread if *terminate_on_pause* not disabled or just mute and encode incoming frames), so if you have a /black box/ with SDI inputs and outputs and IP control - that is an only method... If you are connected to the avformat consumer for file capture, how are you providing preview? passthrow SDI output I would think you would have it connected to another consumer, like SDL, during preview, and then connect it to the avformat consumer for capture with no pausing the producer in between. Unless perhaps you are using the multi consumer. thanks to idea... btw, are there any samples for this functionality? it is like *tie* ? -- Maksym Veremeyenko -- Keep Your Developer Skills Current with LearnDevNow!
