Abstract: Methods for compensating timing errors in an A/V stream are provided. An embodiment of the methods includes: receiving a plurality of encoded video frames of a current Group of pictures (GOP) from the video encoder and a plurality of encoded audio frames; when an error occurs in the video encoder, utilizing a most recent encoded video frame of a previous GOP received from the video encoder as a reference to generate a plurality of dummy video frames; and utilizing the dummy video frames to pad the current GOP.
