Implemented Interfaces

GDataYouTubeService implements GDataBatchable.

Includes

#include <gdata/services/youtube/gdata-youtube-service.h>

Description

GDataYouTubeService is a subclass of GDataService for communicating with the GData API of YouTube. It supports querying for and uploading videos using version 3 of the API.

The YouTube API supports returning different sets of properties for GDataYouTubeVideos depending on the specific query. For search results, only ‘snippet’ properties are returned (including “title”, “summary” and the set of thumbnails). For querying single videos, a more complete set of properties are returned — so use gdata_service_query_single_entry_async() to get further details on a video.

For more details of YouTube's GData API, see the online documentation.

Functions

gdata_youtube_service_new ()

GDataYouTubeService *
gdata_youtube_service_new (const gchar *developer_key,
                           GDataAuthorizer *authorizer);

Creates a new GDataYouTubeService using the given GDataAuthorizer. If authorizer is NULL, all requests are made as an unauthenticated user. The developer_key must be unique for your application, and as

registered with Google.

Parameters

developer_key

your application's developer API key

 

authorizer

a GDataAuthorizer to authorize the service's requests, or NULL.

[allow-none]

Returns

a new GDataYouTubeService, or NULL; unref with g_object_unref()

Since: 0.9.0


gdata_youtube_service_get_primary_authorization_domain ()

GDataAuthorizationDomain *
gdata_youtube_service_get_primary_authorization_domain
                               (void);

The primary GDataAuthorizationDomain for interacting with YouTube. This will not normally need to be used, as it's used internally by the GDataYouTubeService methods. However, if using the plain GDataService methods to implement custom queries or requests which libgdata does not support natively, then this domain may be needed to authorize the requests.

The domain never changes, and is interned so that pointer comparison can be used to differentiate it from other authorization domains.

Returns

the service's authorization domain.

gdata_youtube_service_upload_video ()

GDataUploadStream *
gdata_youtube_service_upload_video (GDataYouTubeService *self,
                                    GDataYouTubeVideo *video,
                                    const gchar *slug,
                                    const gchar *content_type,
                                    GCancellable *cancellable,
                                    GError **error);

Uploads a video to YouTube, using the properties from video and the file data written to the resulting GDataUploadStream.

If video has already been inserted, a GDATA_SERVICE_ERROR_ENTRY_ALREADY_INSERTED error will be returned. If no user is authenticated with the service, GDATA_SERVICE_ERROR_AUTHENTICATION_REQUIRED will be returned.

The stream returned by this function should be written to using the standard GOutputStream methods, asychronously or synchronously. Once the stream is closed (using g_output_stream_close()), gdata_youtube_service_finish_video_upload() should be called on it to parse and return the updated GDataYouTubeVideo for the uploaded video. This must be done, as video isn't updated in-place.

In order to cancel the upload, a GCancellable passed in to cancellable must be cancelled using g_cancellable_cancel(). Cancelling the individual GOutputStream operations on the GDataUploadStream will not cancel the entire upload; merely the write or close operation in question. See the “cancellable” for more details.

Any upload errors will be thrown by the stream methods, and may come from the GDataServiceError domain.

Parameters

self

a GDataYouTubeService

 

video

a GDataYouTubeVideo to insert

 

slug

the filename to give to the uploaded file

a GDataYouTubeService

 

upload_stream

the GDataUploadStream from the operation

 

error

a GError, or NULL
