FFMPEG - 找不到编解码器参数

我试图通过FFMPEG将一系列图像转换为mpeg电影,虽然我不断收到错误,说它无法找到代码参数(视频:mjpeg).谷歌搜索没有带来太多有用的东西.

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

有任何想法吗？

谢谢 - 坦纳

ffmpeg实际上试图告诉你的是,你的文件有jpeg的扩展名,但文件实际上是bmp或其他格式.

确保文件以jpeg编码,问题将消失.

这里的一些人说这是因为无法真正找到mjpeg编解码器.他们建议从源头安装它.我觉得mjpeg更有可能没有安装.我觉得这有两个解决方案.

您可以尝试安装该编解码器,看看它是否有助于 MJpeg下载For Win

您可以尝试强制ffmpeg将其导出到不同的编解码器中尝试:ffmpeg -f image2 -i /tmp/img%03d.jpg -vcodec mpeg2video video.mpg
