我使用以下命令将音频与 webm视频合并。但是c
command = new String[]{"-i", inputvideoFileAbsolutePath, "-i", inputaudioFileAbsolutePath, "-c:v", "copy", "-c:a", "aac", "-map", "0:v:0", "-map", "1:a:0", "-shortest", outputFileAbsolutePath};
其中outputFileAbsolutePath扩展名为mp4。
但是命令失败并出现以下错误。但是命令似乎与其他输入视频格式（mp4，avi，mov，3gp）一起使用。为什么我在使用webm视频时出现此错误以及如何解决它
主要错误 -
无法为输出文件＃0写入标头（编解码器参数不正确 ？）：参数无效
完成错误 -
