FFMPEG - 未找到编解码器参数 [英] FFMPEG - Not finding codec parameters

问题描述

我正在尝试通过FFMPEG将一系列图像转换为mpeg电影，尽管我不断收到一条错误，表示找不到代码参数（Video：mjpeg）。 Google搜索并没有带来很大的帮助。

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.

图像位于/ tmp目录中，名称如img001.jpg和img002.jpg。

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

任何想法？

推荐答案

ffmpeg其实是试图告诉你的是，你的文件有jpeg的扩展名，但这个文件实际上是bmp或者其他格式的。

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.

确保该文件以jpeg编码，问题将消失。

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