直播視訊 API

排程播放時間

排定直播視訊已在第 12.0 版中停用，並將於 2021 年 12 月 14 日在所有版本中停用。呼叫包含 planned_start_time 參數的 POST /ID/live-video 端點將傳回錯誤。

您可用直播視訊 API 建立直播視訊播放，在從建立日期起最長七天內的預定時間直播。

排程播放時間

在用戶、粉絲專頁、社團或活動上建立開始日期在未來的直播視訊播放：

POST /{node-id}/live_videos?status=SCHEDULED_UNPUBLISHED&planned_start_time={start-time}

使用 planned_start_time 參數和 UNIX 時間戳記，指示所要的開始時間。

這會在目標節點上建立 LiveVideo 物件，並傳回直播視訊的 secure_stream_url 和 id。在排程的開始時間或之前，在編碼器上使用加密串流影片網址，將直播視訊資料串流至 LiveVideo 物件。一收到串流資料後，播放便會在預定的開始時間出現在節點的動態時報／摘要上。

排程的播放可在開始日期之前的任何時間點接收串流資料，以供預覽之用。

預覽播放

您可用直播視訊 API 來預覽未發佈的直播視訊播放；所建立之 LiveVideo 物件的 status 設為 SCHEDULED_UNPUBLISHED 或 UNPUBLISHED。

若要預覽未發佈的直播視訊播放，請發送要求至：

GET /{live_video_id}?fields={fields}

使用 {fields} 參數取得 LiveVideo 物件的 dash_preview_url。

要求範例

curl -i -X GET \
 "https://graph.facebook.com/{live-video-id}
    ?fields=dash_preview_url
     &access_token={access-token}"
GraphRequest request = GraphRequest.newGraphPathRequest(
  accessToken,
  "/{live-video-id}",
  new GraphRequest.Callback() {
    @Override
    public void onCompleted(GraphResponse response) {
      // Insert your code here
    }
});

Bundle parameters = new Bundle();
parameters.putString("fields", "dash_preview_url");
request.setParameters(parameters);
request.executeAsync();
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
    initWithGraphPath:@"/{live-video-id}"
           parameters:@{ @"fields": @"dash_preview_url",}
           HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
    // Insert your code here
}];
FB.api(
  '/{live-video-id}',
  'GET',
  {"fields":"dash_preview_url"},
  function(response) {
      // Insert your code here
  }
);
try {
  // Returns a `FacebookFacebookResponse` object
  $response = $fb->get(
    '/{live-video-id}',
    '{fields:dash_preview_url}',    
    '{access-token}'
  );
} catch(FacebookExceptionsFacebookResponseException $e) {
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(FacebookExceptionsFacebookSDKException $e) {
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}
$graphNode = $response->getGraphNode();

回應範例

{
  'dash_preview_url': 'https://video.xx.fbcdn.net/...',
  'id': '{live-video-id}'
}

這會傳回直播視訊的 dash_preview_url 和 id。複製網址並貼在 Dash Player 中，即可預覽直播。

雖然使用第三方的測試播放器來預覽播放是確認播放內容的好方法，但仍建議您在測試的粉絲專頁上播放。若要在粉絲專頁上播放，您必須是粉絲專頁的管理員或編輯。此外，您還可設定隱私參數，以建立只有您自己看得見的串流影片。

取得排程的播放

若要取得用戶、粉絲專頁、社團或活動上已排程的播放清單，請取得具備 publish_video 權限合適的存取權杖，並發送要求至：

GET /{node-id}/live_videos?broadcast_status=["SCHEDULED_UNPUBLISHED"]

請注意，broadcast_status 值必須是陣列。如需其他值的完整清單，請參閱 LiveVideo 參考資料。

重新排程播放時間

若要變更排程的播放開始時間，請發送要求至：

POST /{live-video-id}?planned_start_time={new-start-time}

{new-start-time} 值必須是 UNIX 時間戳記，指出新的開始時間。成功時，API 會以 LiveVideo 物件的編號回應。

立即開始播放

若要立即開始播放，請發送要求至：
