Error mitigation techniques are provided for video coding system in which input frames are selected for coding either as a Random Access Pictures (“RAP frames”) or as a non-RAP frame. Coded RAP frames may include RAP identifiers that set an ID context for subsequent frames. Coded non-RAP frames may include RAP identifiers that match the RAP identifiers that were included in the coded RAP frames. Thus, in the absence of transmission errors, a coded non-RAP frame should include a RAP identifier that matches the identifier of the preceding RAP frame. If the identifier of a non-RAP frame does not match the identifier of the RAP frame that immediately preceded it, then it indicates that a RAP frame was lost during transmission. In this case, the decoder may engage error recovery processes.
