Question

I would upload a video using the Youtube API v3 with curl in PHP, as described here: https://developers.google.com/youtube/v3/docs/videos/insert

I’ve this function

function uploadVideo($file, $title, $description, $tags, $categoryId, $privacy)
{
    $token = getToken(); // Tested function to retrieve the correct AuthToken

    $video->snippet['title']         = $title;
    $video->snippet['description']   = $description;
    $video->snippet['categoryId']    = $categoryId;
    $video->snippet['tags']          = $tags; // array
    $video->snippet['privacyStatus'] = $privacy;
    $res = json_encode($video);

    $parms = array(
        'part'  => 'snippet',
        'file'  => '@'.$_SERVER['DOCUMENT_ROOT'].'/complete/path/to/'.$file
        'video' => $res
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.googleapis.com/upload/youtube/v3/videos');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $parms);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer '.$token['access_token']));
    $return = json_decode(curl_exec($ch));
    curl_close($ch);

    return $return;
}

But it returns this

stdClass Object
(
    [error] => stdClass Object
        (
            [errors] => Array
                (
                    [0] => stdClass Object
                        (
                            [domain] => global
                            [reason] => badContent
                            [message] => Unsupported content with type: application/octet-stream
                        )

                )

            [code] => 400
            [message] => Unsupported content with type: application/octet-stream
        )

)

The file is an MP4.

Anyone can help?

Unfortunately, we don’t have a specific example of YouTube API v3 uploads from PHP available yet, but my general advice is:

• Use the PHP client library instead of cURL.
• Base your code on this example written for the Drive API. Because the YouTube API v3 shares a common API infrastructure with other Google APIs, examples for doing things like uploading files should be very similar across different services.
• Take a look at the Python example for the specific metadata that needs to be set in a YouTube v3 upload.

In general, there are a lot of things incorrect with your cURL code, and I can’t walk through all the steps it would take to fix it, as I think using the PHP client library is a much better option. If you are convinced you want to use cURL then I’ll defer to someone else to provide specific guidance.
