Remote methods

The Dailymotion Cloud API PHP binding exposes all API methods described in the API reference. A master class named CloudKey exposes all namespaces through object attributes. For instance, a call to the count method in the media namespace would be as follow:

$cloudkey = new CloudKey($user_id, $api_key);
$result = $cloudkey->media->count();

For methods expecting parameters, these must be passed as an associative array:

$media = $cloudkey->media->info(array('id' => $a_media_id));

The returned values (when available) are either stdClass instances (when result is a structure) or arrays of stdClass instances (when result is a list of structures):

# Simple structure response
$media = $cloudkey->media->info(array('id' => $a_media_id));
echo $media->id;

# List of structures response
$page = 1;
while(1) {
    $res = $cloudkey->media->list(array('fields' => array('id', 'meta.title'), 'page' => $page++));
    foreach($res->list as $media) {
        printf("%s %s\n", $media->id, $media->meta->title);
    }
    if ($res->page == $res->pages) {
        break;
    }
}

Local methods

Additional local methods are exposed by the CloudKey class. They are not documented in the API reference and provided as helpers to ease the Dailymotion Cloud API integration.

file->upload_file($path)

This method manages files uploads to the Dailymotion Cloud upload servers. Information pertinent to the API media creation processus (especially the media_set_asset method) will be returned as a dict.

Arguments:

• $path: (required) the path of the uploaded file.

Example:

# source asset upload example
$file = $cloudkey->file->upload_file('path/to/video.mov');
$media = $cloudkey->media->create();
$cloudkey->media->set_asset(array('id' => $media->id, 'asset_name' => 'source', 'url' => $file->url));

media.get_embed_url(id)

This method returns a signed URL to a Dailymotion Cloud player embed (see the API reference for details). The generated URL is perishable, and access is granted based on the provided security level bitmask.

Arguments:

• id: (required) the media id.
• seclevel: the security level bitmask (default is CLOUDKEY_SECLEVEL_NONE, see below for details).
• expires: the UNIX epoch expiration time (default is time() + 7200 (2 hours from now)).
• secure: true to get the https embed url (default is false).

The following arguments may be required if the CLOUDKEY_SECLEVEL_DELEGATE option is not specified in the seclevel parameter, depending on the other options. This is not recommanded as it would probably lead to spurious access denials, mainly due to GeoIP databases discrepancies.

• asnum: the client's autonomous system number (default is None).
• ip: the client's IP adress (default is None).
• useragent: the client's HTTP User-Agent header (default is None).

Example:

// Create an embed URL limited only to the AS of the end-user and valid for 1 hour
$url = $cloudkey->media->get_embed_url(array('id' => $media->id, 'seclevel' => CLOUDKEY_SECLEVEL_DELEGATE | CLOUDKEY_SECLEVEL_ASNUM, 'expires' => time() + 3600));

media.get_stream_url(id)

This method returns a signed URL to a Dailymotion Cloud video stream (see the API reference for details). The generated URL is perishable, and access is granted based on the provided security level bitmask.

Arguments:

• id: (required) the media id.
• asset_name: the desired media asset asset_name name (default is mp4_h264_aac).
• seclevel: the security level bitmask (default is CLOUDKEY_SECLEVEL_NONE, see below for details).
• expires: the UNIX epoch expiration time (default is time() + 7200 (2 hours from now)).
• download: True to get the download url (default is False).
• filename: the download url filename (overrides the download parameter if set).
• version: arbitrary integer inserted in the url for the cache flush. Use this parameter only if needed, and change its value only when a cache flush is required.
• protocol: streaming protocol ('hls', 'rtmp', 'hps' or 'http'). Overrides the download parameter if 'http'.

The following arguments may be required if the CLOUDKEY_SECLEVEL_DELEGATE option is not specified in the seclevel parameter, depending on the other options. This is not recommanded as it would probably lead to spurious access denials, mainly due to GeoIP databases discrepancies.

• asnum: the client's autonomous system number (default is None).
• ip: the client's IP adress (default is None).
• useragent: the client's HTTP User-Agent header (default is None).

Example:

// Create a stream URL limited only to the AS of the end-user and valid for 1 hour
url = cloudkey.media.get_stream_url(id=media['id'], seclevel=CLOUDKEY_SECLEVEL_DELEGATE | CLOUDKEY_SECLEVEL_ASNUM, expires=time() + 3600)
$url = $cloudkey->media->get_stream_url(array('id' => $media->id, 'seclevel' => CLOUDKEY_SECLEVEL_DELEGATE | CLOUDKEY_SECLEVEL_ASNUM, 'expires' => time() + 3600));

Security level options

The security level defines the mechanism used by the Dailymotion Cloud architecture to ensure a mediastream URL access will be limited to a single user or a group of users. The different (combinable) options are:

• CLOUDKEY_SECLEVEL_NONE: the URL access is granted to everyone.

• CLOUDKEY_SECLEVEL_ASNUM: the URL access is granted to the specified AS number only. AS numbers stands for 'Autonomous System number' and roughly map groups of IP to telcos and large organizations on the Internet (each ISP has its own AS number for instance, Dailyotion's AS number is AS41690).

• CLOUDKEY_SECLEVEL_IP: the URL access is granted to the specified IP address only. This option may lead to spurious access denials as some users are load-balanced behind multiple proxies when accessing the Internet (this is mostly the case with ISPs and large organizations).

• CLOUDKEY_SECLEVEL_USERAGENT: the URL access is granted to users sending the specified User-Agent HTTP header only.

• CLOUDKEY_SECLEVEL_DELEGATE: the ASNUM, IP and User-Agent values are to be gathered at the server side during the first URL access and don't need to be specified at the client side beforehand (this is the recommanded approach as it will ensure a 100%-accurate ASNUM recognition).

• CLOUDKEY_SECLEVEL_USEONCE: the URL access is granted once only (using this option will probably prevent seeking from working correctly).

Exceptions

The Dailymotion Cloud API methods may throw exceptions when errors occur, and they should be catched in your code. The available exceptions are:

• CloudKey_Exception: an unexpected API response occured.

• CloudKey_ProtocolException: a transport layer error occured.

• CloudKey_InvalidNamespaceException: an invalid namespace was used.

• CloudKey_InvalidMethodException: an invalid method was called.

• CloudKey_NotFoundException: an action was requested on an invalid item.

• CloudKey_MissingParamException: a mandatory parameter was missing from a method call.

• CloudKey_InvalidParamException: an invalid parameter was specified in a method call.

• CloudKey_AuthorizationRequiredException: an authenticated method was call but no authentication information was provided.

• CloudKey_AuthenticationFailedException: invalid authentication information was provided.
