【问题描述】：
我正在拼命尝试用 ffmpeg 剪切一个 MP4 视频，遵循这个 [example] https://github.com/facebookresearch/VideoPose3D/blob/master/INFERENCE.md
ffmpeg -i P1060513copy.mp4 -ss 3:12 -to 3:30 -c copy output.mp4
我收到了这个错误

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
为避免此错误，我将文件转换为 mkv 并将其剪切（完美运行），然后我想将其转换回 MP4，但以同样的错误结束。
谁能帮帮我？
谢谢
