Question

我一直在尝试将.mov文件转换为.mp4文件一段时间，我认为这是正确的代码。

ffmpeg  -i P1010989.MOV -vcodec copy -acodec copy out.mp4

但这是我的输出

所以我正在尝试安装正确的编解码器而且有点丢失，并提供一些帮助。

我是否需要单独安装编解码器，从哪里下载并安装它们？

代码真的有一些帮助，谢谢。

    Stream #0.1(eng): Audio: pcm_s16be, 16000 Hz, 1 channels, s16, 256 kb/s
[mp4 @ 0x95b0080]track 1: could not find tag, codec not currently supported in container

这告诉你不是缺少编解码器，而是它与MP4格式不兼容。

您可以使用其他音频编解码器解决此问题。

ffmpeg -i P1010989.MOV -vcodec copy -acodec aac -strict -2 -b:a 384k out.mp4

安装mov到mp4转换ffmpeg的编解码器
