I suspect that if you don't want to reencode, you will have to produce the video stream together with silent audio. But I suspect that concatenation of H264 streams that were generated on different systems is not guaranteed to work, so maybe reencoding is unavoidable. Please try the concat demuxer or the concat filter, the concat protocol does not work for mov and friends.
