Prefix chapter title with chapter index

[alainpannetier]

I also tweecked a 'quick & dirty' numbering mod.

    def create_chapter(self, chapter, i) -> bool:
        start = chapter["start_time"]
        end = chapter["end_time"]
        diff = end - start
        args =  [
            "ffmpeg",
            "-i", self.file.media_filepath,
            "-ss", str(start),
            "-t", str(diff),
            "-acodec", "copy",
            "-vcodec", "copy",
            self.file.output_chapter_file(str(i) + "-" + chapter["title"])
            ]
        ret = subprocess.run(args)
        return ret.returncode == 0

Called as follows. A bit ugly.

    def split_into_chapters(self):
        if not self.file.chapters:
            self.log("No chapters available.")
            return False

        if not self.file.create_output_folder():
            self.log("Failed to create output folder.")
            return False

        for i, chapter in enumerate(self.file.chapters):
            if not self.create_chapter(chapter, i):
                self.log("Failed to create chapter " + i + " file: " + chapter["title"])
        return True

I agree this would be a very useful feature. I will look into adding a command line option to do this.

Would be cool to have such a feature
