Correlation of video stream frame timestamps based on a system clock

A computerized method for correlating timestamps of video frames from a capture device, the computerized method comprising:

• receiving, by a correlator application, a frame of a video stream from a capture device via a bus interface, the frame including a first start frame timestamp and a first end frame timestamp based on a device clock associated with the capture device;
• predicting, by the correlator application, based on a plurality of previously received frames of the video stream, a second start frame timestamp and a second end frame timestamp associated with the received frame, the second start frame timestamp and second end frame timestamp being based on a system clock associated with a computing device of the correlator application;
• calculating, by the correlator application, a skew value of the received frame based on a difference between the first start frame timestamp and the second start frame timestamp, and a difference between the first end frame timestamp and the second end frame timestamp;
• upon the calculated skew value exceeding a skew threshold, correcting, by the correlator application, the received frame to correlate to the second start frame timestamp and the second end frame timestamp;
• combining the received frame with the plurality of received frames of the video stream;
• and
• providing the video stream for display.

One or more computer storage media having computer-executable instructions for correlating timestamps of video frames from capture devices that, upon execution by a processor, cause the processor to at least:

• receive a frame of a video stream from a capture device via a bus interface, the frame including a first start frame timestamp and a first end frame timestamp based on a device clock associated with the capture device;
• predict based on a plurality of previously received frames of the video stream, a second start frame timestamp and a second end frame timestamp associated with the received frame, the second start frame timestamp and second end frame timestamp being based on a system clock associated with the processor;
• calculate a skew value of the received frame based on a difference between the first start frame timestamp and the second start frame timestamp, and a difference between the first end frame timestamp and the second end frame timestamp;
• upon the calculated skew value exceeding a skew threshold, correct the received frame to correlate to the second start frame timestamp and the second end frame timestamp;
• and
• provide the corrected frame for display.
