Remarks

The Stream Buffer Sink can receive data only at 1x speed. If the source is a file, the playback speed must be restricted to 1x.

If the Stream Buffer Sink is stopped and restarted, the render graph will lose context and be unable to access the capture graph. However, the tuner can change channels while the graph is running without problems.
