使用 CURL for ffmpeg 像浏览器一样下载

我想在 ffmpeg 参数中输入 HTTP 文件，并且我尝试了这段代码

<?php

    $fname=time().'_myfile.mp3';
    $cmd = "/usr/local/bin/ffmpeg -i 'http://tinyurl.com/url' -vn -b 64k -f mp3 -acodec libmp3lame - $fname"; 
    header('Content-type: audio/mpeg');
    header("Content-Type: application/octet-stream");
    header("Content-Disposition: attachment; filename=\"$fname\"");
    passthru($cmd);

>?

，我尝试传递tinyurl URL，但 ffmpeg 无法创建文件。如果我将其他一些直接 URL 传递给参数，此代码可以正常工作。

我正在考虑创建一个 PHP 文件并使用带有适当标头的 CURL 并在输入参数中传递该 PHP 文件，这样可行吗？简而言之，如果输入不是直接链接，则 ffmpeg 会失败。我应该怎么办？

有人能帮我解决这个问题吗？

I want input HTTP file in ffmpeg parameter and I have tried this code

    $fname=time().'_myfile.mp3';
    $cmd = "/usr/local/bin/ffmpeg -i 'http://tinyurl.com/url' -vn -b 64k -f mp3 -acodec libmp3lame - $fname"; 
    header('Content-type: audio/mpeg');
    header("Content-Type: application/octet-stream");
    header("Content-Disposition: attachment; filename=\"$fname\"");
    passthru($cmd);

I tried to pass tinyurl URL but ffmpeg failed to create file.
This code work fine if I pass some other direct URL to parameter.

I thinking of creating one PHP file and using CURL with proper headers and pass that PHP file in input parameter will that work?
In simple words ffmpeg failed if input is not direct link. What should I do?

Can anybody help me on this?

您可以使用下面的curl 函数来获取真实的URL，从中您应该能够按计划进行。

function resolve($url)
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HEADER => true,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_ENCODING => "",
        CURLOPT_USERAGENT => "spider",
        CURLOPT_AUTOREFERER => true,
        CURLOPT_CONNECTTIMEOUT => 120,
        CURLOPT_TIMEOUT => 120,
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_NOBODY => 1
    );

    $ch = curl_init($url);
    curl_setopt_array($ch, $options);
    $content = curl_exec($ch);
    $err = curl_errno($ch);
    $errmsg = curl_error($ch);
    $header = curl_getinfo($ch);
    curl_close($ch);
    return $header['url'];
}

Based on a comment from http://getsatisfaction.com/soup/topics/reverse_lookup_for_tinyurls
you can use the below curl function to get the real URL from which you should be able to carry on as planned.

function resolve($url)
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HEADER => true,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_ENCODING => "",
        CURLOPT_USERAGENT => "spider",
        CURLOPT_AUTOREFERER => true,
        CURLOPT_CONNECTTIMEOUT => 120,
        CURLOPT_TIMEOUT => 120,
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_NOBODY => 1
    );

    $ch = curl_init($url);
    curl_setopt_array($ch, $options);
    $content = curl_exec($ch);
    $err = curl_errno($ch);
    $errmsg = curl_error($ch);
    $header = curl_getinfo($ch);
    curl_close($ch);
    return $header['url'];
}
