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。我也尝试过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
