Lambda未连接到ffmpeg [英] Lambda not connecting to ffmpeg

问题描述

我遇到一个Lambda函数问题，该函数试图将ffmpeg用作AWS上的第三方.该函数本身使用ffmpeg.js库，该库在调用函数时会在其函数中生成ffmpeg命令.我通过SSH在实例上安装了ffmpeg，但仍然给我同样的错误

I have an issue with a Lambda function that tries to use ffmpeg as a third party on AWS. The function itself uses ffmpeg.js library which generates ffmpeg commands in it's functions, when they are called. I installed ffmpeg on my instance via SSH, and it's still giving me the same error

命令失败:ffmpeg -i".... ffmpeg:找不到命令

Command failed: ffmpeg -i ".... ffmpeg: command not found

对此有何建议?非常感谢

Any advice on this? Many thanks

推荐答案

您需要在项目目录中包含ffmpeg的静态构建

You need to include static build of ffmpeg inside your project directory

下载x86_64版本.因为它使用了我的lambda环境

解压缩文件，然后复制名为ffmpeg的二进制构建文件，并将其粘贴到您的项目目录中.

Unzip the file and copy ffmpeg named file which is binary build and paste it in your project directory.

之后，在代码顶部粘贴以下代码段:

After that on the top of your code paste the following snippet:

process.env.PATH = process.env.PATH + ':/tmp/'
process.env['FFMPEG_PATH'] = '/tmp/ffmpeg';
const BIN_PATH = process.env['LAMBDA_TASK_ROOT'] 
rocess.env['PATH'] = process.env['PATH'] + ':' + BIN_PATH;

现在，在exports.handler中，将以下代码行粘贴到函数调用的开头.看起来像这样

Now inside your exports.handler, paste the following line of code in the beginning of function call. It will look like this

exports.handler = function(event, context, callback) {
require('child_process').exec(
'cp /var/task/ffmpeg /tmp/.; chmod 755 /tmp/ffmpeg;',
function (error, stdout, stderr) {
if (error) {
console.log('Erro occured',error);
} else {
var ffmpeg = require('ffmpeg');
// Your task to be performed
}
}
)
}

我希望这会有所帮助.别忘了竖起大拇指:) 上面的解决方案是针对Node.js语言的

I hope this helps. Don't forget to leave a thumbs up :) Above solution is for Node.js language
