FFMPEG - 找不到编解码器参数

问题描述

我正在尝试通过 FFMPEG 将一系列图像转换为 mpeg 电影，尽管我一直收到错误消息，说它找不到代码参数(视频:mjpeg).Google 搜索并没有提供多少有用的信息.

图片驻留在/tmp目录中，名称为img001.jpg和img002.jpg.

有什么想法吗?

谢谢-坦纳

解决方案

ffmpeg 实际上想告诉您的是，您的文件具有 jpeg 扩展名，但该文件实际上是 bmp 或某种其他格式.

确保文件以jpeg编码，问题就会消失.

I'm trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video: mjpeg). A Google search did not bring much up that was useful.

The images reside in the /tmp directory with names such as img001.jpg and img002.jpg.

Any ideas?

Thanks-Tanner

解决方案

What ffmpeg is actually trying to tell you is, that your file has extension of jpeg, but the file actually is bmp or some other format.

Make sure that the file is encoded in jpeg and the problem will disappear.
