Example:

    {
      "tool": "mp4box:cat",
      "parameters": {
        "fps": "23.976",
        "flat": "True",
        "inputs": [
          "chunk_001.mp4",
          "chunk_002.mp4"
        ],
        "output_dir": "out",
        "output": "file.mp4"
      }
    },

Parameter	Properties	Default	Type	Description
fps	required			Frame rate. type: float
inputs	required [list value]			List of MP4 files to concatenate, or single path with wildcard expression: *
output	required			MP4 output file
flat	optional	true	bool	store file with all media data first, non-interleaved. This speeds up writing time when creating new files. By default all imports are performed sequentially, and final interleaving is done at the end; this however requires a temporary file holding original ISOBMF file (if any) and added files before creating the final output. Since this can become quite large, it is possible to add media to a new file without temporary storage, using -flat option, but this disables media interleaving.
output_dir	optional			Output folder
