【问题标题】：FFMPEG : Invalid data found when processing inputFFMPEG：处理输入时发现无效数据【发布时间】：2019-08-24 18:36:37 【问题描述】：

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

【问题讨论】：

似乎您的视频没有扩展名，但 ffmpeg 从其扩展名预测输入文件格式。请参阅 ffmpeg 手册中的-f format 选项。
