I am an object that can play out a 4K or UHD test pattern (with timecode) to an output of an AJA device with or without audio tone in real time. I make use of the AJACircularBuffer, which simplifies implementing a producer/consumer model, in which a "producer" thread generates the test pattern frames, and a "consumer" thread (i.e., the "play" thread) sends those frames to the AJA device. I show how to configure 12G-capable devices, or for two-sample-interleave or "squares" (quadrants). More...
