System and method for determining video codec performance in real-time communication over internet

A video codec performance evaluation system for evaluating the performance of a video codec in real-time communication (RTC) use cases, said video codec performance evaluation system comprising:

• (1) a video codec performance evaluation network model adapted to assess a video codec's performance relative to a reference video codec, said video codec including a video encoder and a video decoder, said video codec performance evaluation network model adapted to:
• a. build a set of f-g lookup tables including packet loss ratio values, network latency values, retransmission values, arriving probability values and expected arriving delay values;
• b. determine a set of quantization parameter values;
• c. determine a set of seeds for random number generation;
• and
• d. for each value within said set of quantization parameter values and each value within said set of seeds, determine a set of frame decoding data items for a video sequence, thereby forming a list of sets of frames decoding data items, said video sequence including a set of frames;
• and
• (2) a video codec quality analyzer adapted to:
• a. from each set of frame decoding data items within said list of sets of frame decoding data items,
• i. determine a decodable frame ratio, thereby forming a list of decodable frame ratios;
• ii. determine a delay of decodable frames, thereby forming a list of delays of decodable frames;
• and
• iii. determine a video fluency, thereby forming a list of video fluencies;
• b. from said list of decodable frame ratios, determine a final decodable frame ratio;
• c. from said list of delays of decodable frames, determine a final delay of decodable frames;
• and
• d. from said list of video fluencies, determine a final video fluency.
