(For future questions: Never post extracts of the console output, always the command line you tested together with the complete, uncut console output.) Once upon a time, a java tool called ProjectX did what you need, to some degree it also worked with h264 video. I believe there is a specific ts tool that replaces it today, I never used it. You should be able to remux with FFmpeg (although h264 timestamps sometimes prevent this).
