问题[wav](ubuntu)

尝试使用 ffmpeg 将 wav 文件转换为 mp3 时，我继续收到此错误。

这是我正在运行的命令

ffmpeg -i 11_22_40AM.wav  -acodec mp3 11_22_40AM.mp3

这就是错误

[gsm_ms @ 0x5567d18626c0] Packet is too small
Error while decoding stream #0:0: Invalid data found when processing input

以及由命令引起的所有输出

ffmpeg -i 11_22_40AM.wav  -acodec mp3 11_22_40AM.mp3

我正在尝试将一个格式的音乐文件转换.gsm为 format .wav。这就是我尝试的方式：

for f in *.gsm; do sox $f new/${f%.wav}; done

结果是我在目录中得到了相同格式的相同.gsm文件new/。

谁能指出这里的问题是什么？
