Mixer internals

+ +
+

+ To simplify the diagram, I omitted connection setup, tally light + and recording control, and the internal sinks that haven't been + implemented yet. +

+

+ All these interfaces have limited-length queues. If a queue + fills up, frames have to be dropped - we must not block or use + unlimited memory! +

+

+ The mixer clock thread maintains a frame clock at about 25 or + 30 Hz depending on the video system, constantly adjusted to + follow the audio source. +
