Abstract
In one embodiment, a method receives packets including video data that was encoded or decoded. The packets are dynamically routed through processing elements in different routes and some of the packets include signatures from processing elements that processed each respective packet. The method then determines a plurality of captures each including a set of packets and determines for each capture, a set of processing elements that processed the set of packets. The set of processing units inserted respective signatures into a user data section of the packets that is defined by a standard used to encode or decode the video data. The determined set of processing elements are analyzed for each capture to determine a processing element in the set of processing elements that is considered to be causing a performance degradation. Then, the method performs a remedial action associated with the processing element.
