Error: ffmpeg exited with code 1 on AWS Lambda

Question

我正在使用 fluent-ffmpeg nodejs 包到运行 ffmpeg 在 AWS Lambda 上进行音频转换。我正在为 lambda 使用 this FFmpeg 层。这是我的代码

  const bitrate64 = ffmpeg("file.mp3").audioBitrate('64k');
    bitrate64.outputOptions([
        '-preset slow',
    '-g 48',
    "-map", "0:0",
        '-hls_time 6',
        '-master_pl_name master.m3u8',
        '-hls_segment_filename 64k/fileSequence%d.ts'
    ])
    .output('./64k/prog_index.m3u8')
    .on('progress', function(progress) {
        console.log('Processing 64k bitrate: ' + progress.percent + '% done')
    })  
    .on('end', function(err, stdout, stderr) {
        console.log('Finished processing 64k bitrate!')
    })
    .run()

在通过 AWS lambda 运行连接它之后，我收到以下错误消息

ERROR   Uncaught Exception  
{
    "errorType": "Error",
    "errorMessage": "ffmpeg exited with code 1: Conversion failed!\n",
    "stack": [
        "Error: ffmpeg exited with code 1: Conversion failed!",
        "",
        "    at ChildProcess.<anonymous> (/var/task/node_modules/fluent-ffmpeg/lib/processor.js:182:22)",
        "    at ChildProcess.emit (events.js:198:13)",
        "    at ChildProcess.EventEmitter.emit (domain.js:448:20)",
        "    at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)"
    ]
}

我没有得到更多信息，所以我不确定发生了什么。谁能告诉我这里出了什么问题以及如何启用更详细的日志？

Answer 1

添加了错误回调以获取详细错误并发现 lambda 存在权限问题

   .on('error', function(err, stdout, stderr) {
        if (err) {
            console.log(err.message);
            console.log("stdout:\n" + stdout);
            console.log("stderr:\n" + stderr);
            reject("Error");
        }
    })
