php亚马逊弹性转码器

Question

I am trying to execute a job that will transcoder a video file... I have a php file:

<?php
require 'vendor/autoload.php';

use Aws\ElasticTranscoder\ElasticTranscoderClient;

// Create a service locator using a configuration file
$client = ElasticTranscoderClient::factory(array(
        'key'    => 'my key',
        'secret' => 'my secret',
        'region' => 'us-west-2',
));

$result = $client->createJob(array(
        'PipelineId' => 'my pipeline id',
        'Input' => array(
                'Key' => 'video.mp4',
                'FrameRate' => 'auto',
                'Resolution' => 'auto',
                'AspectRatio' => 'auto', 
                'Interlaced' => 'auto',
                'Container' => 'auto',
        ),
        'Output' => array(
                'Key' => 'output.mp4',
                'ThumbnailPattern' => 'thumb{count}.jpg',
                'Rotate' => 'auto',
                'PresetId' => '1351620000001-000010',
        ),
));

?>

and I call this script like transcoder.php

The thing is that if I call this from my root from VPS like php transcoder.php it works just fine, but if I try to call it from my browser (safari, chrome, firefox) I get a

Fatal error: Uncaught exception 'Aws\ElasticTranscoder\Exception\ElasticTranscoderException' in /home/my_user/public_html/test/vendor/aws/aws-sdk-php/src/Aws/Common/Exception/NamespaceExceptionFactory.php:91

Any idea why it works from root and why it doesn't work from browser? I need to access it from browser.

Answer 1

尝试从 php.ini 更改有关 curl 和 exec 的设置，这就是为什么您无权从浏览器访问脚本，但可以从根控制台访问。

Answer 2

Firstly, put a try/catch statement around the code to see the whole error message which will help diagnose the problem.

I suspect it's because the files you are passing in Key do not exist as the working directory can be different if you execute on the command line vs apache.

Try specifying the full path to video.mp4 and see if that works.
