Node.js ffmetadata不正确的编解码器参数

标签: node.js ffmpeg

我正在Node.js制作一个歌曲下载器应用程序。我设法让一切工作,应用程序下载歌曲并下载其艺术作品(图像)。所以我有mp3文件和jpg文件。唯一的问题是将jpg文件附加到mp3文件。

我正在使用ffmetadata node.js模块。我下载并安装了它的依赖“ffmpeg”cli。

现在,当我尝试将元数据写入mp3文件并附加图片时,它会发出此错误:

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

我的代码:

ffmetadata.write('test.mp3', {}, {attachments: ['test.jpg']}, function(err) {
  if (err) console.error(err);
});

错误:

阅读输出:

Stream #0:0(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 125 kb/s (default)

[mp3 @ 0000000004865d80] Invalid audio stream. Exactly one MP3 audio stream is required

Stream mapping: Stream #0:0 -> #0:0 (copy) Stream #1:0 -> #0:1 (copy)

您的输入文件不是MP3而是MP4A / AAC。它有错误的扩展名。然后,您尝试将AAC流复制为MP3,这显然会失败。检查下载程序中的源文件。
