我正在尝试将音频文件添加到使用 FFmpeg 从图像生成的视频文件中。
我在 Debian 发行版上使用的命令是这个
ffmpeg -r 1 -i edit%0d.jpg outputName.mp4 -i Test.mp3
视频文件已创建，但音频不起作用。
输出 ：：

在 Windows 上它运行良好，我尝试了多种场景，但似乎找不到问题，也许是编解码器问题？
谢谢 ！
更新 ：
我设法通过以下方式修复它：
ffmpeg -r 1 -i edit%0d.jpg -i Test.mp3 -ar 44100 -strict experimental

仅映射视频流：

我很确定您仍然必须在那里指定比特率和分辨率。
以前也做过类似的事情：为 YouTube 创建带有音频和静态图像的视频
