Fluent-FFmpeg错误: ffprobe已退出，代码为%1

我正在使用Lambda函数将给定的文件拆分成多个片段，并且在文件处理过程中经常收到一个错误：

}我看到了错误消息，它告诉我的是什么，但我不能理解的是，这个文件有时是有效的。在这个过程开始之前，我将文件从S3下载到我的Lambda容器中，也许这是我的问题，但它有时仍然有效。

经过长时间的调查，我发现我的问题确实是如何从S3下载我的源文件，所以在修复这个问题之后，没有抛出更多的错误！
为了以后的参考，这里是我的过程中所发生的变化，希望对将来的人有所帮助。
这是它下载文件的方式：
return new Promise((resolve: Function, reject: Function): void => {
const s3Stream: stream.Readable = this.client.getObject(params).createReadStream()
const fileStream: stream.Writable = fs.createWriteStream(filePath)
s3Stream.on('error', () => {
fileStream.destroy()
reject()
})
fileStream.on('error', () => {
s3Stream.destroy()
reject()
})
s3Stream.pipe(fileStream)
.on('close', resolve())
})
}现在，在更改之后：
return new Promise((resolve: Function, reject: Function): void => {
const fileStream: stream.Writable = fs.createWriteStream(filePath)
this.client.getObject(params)
.on('error', (err: NodeJS.ErrnoException) => {
fileStream.destroy()
reject(err)
})
.on('httpData', (chunk: unknown) => {
fileStream.write(chunk);
})
.on('httpDone', () => {
fileStream.end();
resolve()
})
.send();
})
