FFMPEG：处理输入时发现无效数据

Question

我无法上传 mp3 或 mp4 是否有任何特定的路径格式？这是我的代码。我也试过这个ffmpeg -i Video/" + Name + " -ss 01:30 -r 1 -an -vframes 1 -f mjpeg Video/" + Name + ".jpg

exec("ffmpeg -y -i Video/" + Name + " -map_metadata -1 -ab 192k Video/" + Name + ".jpg", function(err) {
            if (err) {console.log(err)}
        console.log('Done', {'Image' : 'Video/' + Name + '.jpg'});
        });

这是错误

{ Error: Command failed: ffmpeg -y -i Video/ac9358e25dd41a69e95a72d3e71e4881 -map_metadata -1 -ab 192k Video/ac9358e25dd41a69e95a72d3e71e4881.jpg

尝试添加确切的文件扩展名，如果文件是 mp4，则添加“.mp4”
