Yes, it is possible to add a timecode to each chapter in an mp4 container.

To do this, you can use the -timecode option in FFmpeg. This option allows you to specify a timecode for each chapter in the mp4 container.

Here is an example command that you can use to add timecodes to each chapter in an mp4 container:

ffmpeg -i input.mp4 -map 0 -c copy -metadata:s:t:0 timecode="00:00:00:00" -timecode_frame_start 0 output.mp4
In this command, the -timecode option is used to specify a timecode for each chapter in the mp4 container. The timecode is specified in the format HH:MM:SS:FF, where HH represents the hours, MM represents the minutes, SS represents the seconds, and FF represents the frames.

In this example, the timecode for each chapter is set to 00:00:00:00, which represents the start of the video. You can adjust this timecode as needed to specify different timecodes for each chapter.
