mp3 中有一个图像，也许是一些专辑图像。当我使用ffmpeg将其转换为mp4时，出现错误。但如果我转换没有图像的 mp3，它就会成功。
我的命令是这样的:
ffmpeg -i input.mp3 output.mp4
错误如下:
Stream mapping:
Stream #0:1 -> #0:0 (mjpeg -> mpeg4)
Stream #0:0 -> #0:1 (mp3 -> aac)
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
这是所有控制台输出:

最佳答案
使用-vn删除视频流。
ffmpeg -i input.mp3 -vn output.mp4
