目的： 提取input.mp4的第1024帧，并叠加在backround.jpg的(100,50)处 我尝试使用如下命令，但它生成的图和backround.jpg是一样的 ```bash ffmpeg -i "input.mp4" -i backround.jpg -filter_complex [0:v]select=eq(n\,1024)[frame];[1:v][frame]overlay=100:50 -frames:v 1 output.jpg -y ``` 快速生成一个backround.jpg ```bash ffmpeg -f lavfi -i color=c=0xcaff70:s=3840x2160 -vframes 1 backround.jpg -y ``` 如果单独提取指定帧生成图像文件，再作为输入是可行的，如果想直接得到最终输出，有办法实现吗？
