我曾尝试使用以下命令进行转换

I was tried to convert it using the following command

它引发错误

[opus @ 0x56489c7f9840] LBRR frames is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.

如何解决此问题?我已经在VLC中播放了文件，并且可以听到源文件中的声音.但是转换失败

How to fix this issue? I have played the file in VLC and I can hear the sound from the source file. But failed to convert it

推荐答案

您的 ffmpeg 太旧了

更新您的 ffmpeg :

• 下载已编译的 ffmpeg
• 或者请参见在FFmpeg Wiki上编译指令

这是票证#4641:解码SILK帧时出错.该修补程序比最新的发行版分支(截至撰写本文时为FFmpeg 4.3)要新，因此您必须从git master分支中获取构建(上面的两个链接都可以)，或者等待FFmpeg 4.4.

This was ticket #4641: Error decoding SILK frame. The fix is newer than the most current release branch (FFmpeg 4.3 as of writing this), so you have to get a build from the git master branch (either of the links above will do), or wait for FFmpeg 4.4.

如果您无法更新 ffmpeg ，则旧的解决方法是使用libopus进行解码:

If you can't update your ffmpeg the old workaround is to use libopus to decode:

ffmpeg -c:a libopus -i input ...
