“编码器‘aac’是实验性的，但未启用实验性编解码器" [英] "The encoder 'aac' is experimental but experimental codecs are not enabled"

问题描述

在使用 FFMPEG 将 flv 转换为 mp4 转换时，它显示以下错误

While converting flv to mp4 conversion using FFMPEG it's showing following error

[aac @ 0x2b4b640] 编码器 'aac' 是实验性的，但实验性编解码器未启用，如果您想使用它，请添加 '-strict -2'.

[aac @ 0x2b4b640] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

推荐答案

实际上在命令行中添加 -strict -2 还不够.添加 -strict -2 的位置非常重要，不幸的是，错误消息中没有解释这一点.应该就在最后一个参数之前，即如下:

Actually it is not enough to add -strict -2 to the command line. It is very important where the -strict -2 is added and unfortunately this is not explained in the error message. It should be just before the last argument, that is, as follows:

ffmpeg -i infile -strict -2 outfile
