当我尝试将 avi 文件与 wav 文件合并时，它显示错误“打开输出流 #0:1 的编码器时出错 - 可能是不正确的参数，例如 bit_rate、rate、width 或 height”。
我将在此处包含我的代码以及命令行输出。
代码：
ffmpeg -i“C:\Users\admin\Desktop\SUNP0001.AVI”-i“C:\Users\admin\Desktop\temp.wav”-c：v 复制-c：a aac -strict 实验“C:\Users\admin\Desktop\new1.avi”
命令行输出
E:\vishnu>ffmpeg -i "C:\Users\admin\Desktop\SUNP0001.AVI" -i "C:\Users\admin\De
sktop\temp.wav" -c:v copy -c:a aac -strict experimental "C:\Users\admin\Deskto
p\new1.avi"

请帮忙。
答案1
对于 11,025 Hz 单声道音频来说，您的比特率太高。128 kBit/s 对编码器来说太多了。
您需要通过添加-b:a 32k或类似操作来降低比特率。
