some programs use ffmpeg to copy video that we do not want, removeing ffmpeg.exe will cause some unintended error, so we use this fake ffmpeg to avoid that.

moveFileOnly.c

#include <stdio.h>

int main(int argc, char *argv[]) {
    if (argc < 2) {
        printf("!!!DDTV DO NOT copy my files!!!\nUsage: \nMove this program to plugins/ffmpeg/ffmpeg.exe\n");
        return 1;
    }
    char *input = NULL;
    for (int i = 0; i < argc - 1; ++i) {
        if (argv[i][0] == '-') {
            if (argv[i][1] == 'i') {
                input = argv[i + 1];
                break;
            }
        }
    }
    if (NULL == input) {
        printf("Can not find input file\n");
        return 2;
    }
    char *output = argv[argc - 1];
    return rename(input, output);
}

Here is a Golang version, which will get a too large product.

package main

import (
	"flag"
	"fmt"
	"os"
)

var InFile string
var OutFile string

func main() {
	flag.StringVar(&InFile, "i", "", "Input file")
	flag.StringVar(&OutFile, "o", "", "output file")
	flag.Parse()
	file := flag.Args()
	if InFile == "" {
		fmt.Println(`!!!DDTV Do NOT copy my files!!!`)
		fmt.Println(`Can not find input arguments`)
		fmt.Println(file)
		fmt.Println(`Usage: ./ffmpeg.exe -i input.mp4 -o output.mp4`)
		return
	}
	if OutFile == "" {
		a := len(file)
		if a > 0 {
			OutFile = file[a-1]
		}
	}
	if OutFile == "" {
		os.Exit(1)
	}
	err := os.Rename(InFile, OutFile)
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(2)
	}
	return
}
