我可以通过Youtube api创建一个活动。事件将显示在我的Youtube页面＆＃34; events标签＆＃34; （即将到来的类别）。 但是当我开始流式传输时，它返回错误403（流不活动）。我想在每次上线时创建一个新的广播事件。 任何帮助将不胜感激。这是我的代码......
这是AsyncTask：
YouTube youtube = new YouTube.Builder(transport, jsonFactory,
credential).setApplicationName(APP_NAME).build();
YouTubeApi.createLiveEvent(youtube, "event description", "event name");
方法YoutubeApi.createLiveEvent(...)：
public static void createLiveEvent(YouTube youtube, String description,
String name) {
try {
LiveBroadcastSnippet broadcastSnippet = new LiveBroadcastSnippet();
broadcastSnippet.setTitle(name);
broadcastSnippet.setScheduledStartTime(new DateTime(new Date()));
LiveBroadcastContentDetails contentDetails = new LiveBroadcastContentDetails();
MonitorStreamInfo monitorStream = new MonitorStreamInfo();
monitorStream.setEnableMonitorStream(false);
contentDetails.setMonitorStream(monitorStream);
// Create LiveBroadcastStatus with privacy status.
LiveBroadcastStatus status = new LiveBroadcastStatus();
status.setPrivacyStatus("public");
LiveBroadcast broadcast = new LiveBroadcast();
broadcast.setKind("youtube#liveBroadcast");
broadcast.setSnippet(broadcastSnippet);
broadcast.setStatus(status);
broadcast.setContentDetails(contentDetails);
// Create the insert request
YouTube.LiveBroadcasts.Insert liveBroadcastInsert = youtube
.liveBroadcasts().insert("snippet,status,contentDetails",
broadcast);
// Request is executed and inserted broadcast is returned
LiveBroadcast returnedBroadcast = liveBroadcastInsert.execute();
// Create a snippet with title.
LiveStreamSnippet streamSnippet = new LiveStreamSnippet();
streamSnippet.setTitle(name);
// Create content distribution network with format and ingestion
// type.
CdnSettings cdn = new CdnSettings();
cdn.setFormat("240p");
cdn.setIngestionType("rtmp");
LiveStream stream = new LiveStream();
stream.setKind("youtube#liveStream");
stream.setSnippet(streamSnippet);
stream.setCdn(cdn);
// Create the insert request
YouTube.LiveStreams.Insert liveStreamInsert = youtube.liveStreams()
.insert("snippet,cdn", stream);
// Request is executed and inserted stream is returned
LiveStream returnedStream = liveStreamInsert.execute();
// Create the bind request
YouTube.LiveBroadcasts.Bind liveBroadcastBind = youtube
.liveBroadcasts().bind(returnedBroadcast.getId(),
"id,contentDetails");
// Set stream id to bind
liveBroadcastBind.setStreamId(returnedStream.getId());
// Request is executed and bound broadcast is returned
liveBroadcastBind.execute();
} catch (GoogleJsonResponseException e) {
System.err.println("GoogleJsonResponseException code: " + e.getDetails().getCode() + " : " + e.getDetails().getMessage());
e.printStackTrace();
} catch (IOException e) {
System.err.println("IOException: " + e.getMessage());
e.printStackTrace();
} catch (Throwable t) {
System.err.println("Throwable: " + t.getStackTrace());
t.printStackTrace();
}
}
以下是启动事件流的代码：
public static void startEvent(YouTube youtube, String broadcastId) // broadcast id is same(checked)
throws IOException {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
Log.e(APP_NAME, "", e);
}
YouTube.LiveStreams.List liveBroadcastRequest = youtube
.liveStreams().list("id,snippet,status");
// liveBroadcastRequest.setMine(true);
liveBroadcastRequest.setId(broadcastId); // setBroadcastStatus("upcoming");
// List request is executed and list of broadcasts are returned
LiveStreamListResponse returnedListResponse = liveBroadcastRequest.execute();
List<LiveStream> returnedList = returnedListResponse.getItems();
Transition transitionRequest = youtube.liveBroadcasts().transition(
"live", broadcastId, "status");
transitionRequest.execute();
}

您需要等待流状态切换为active。因此，您必须存储您的流ID和广播ID，等待此状态。
可以使用TimerTask或ScheduledExecutorService：
mScheduleTaskExecutor = Executors.newSingleThreadScheduledExecutor();
// check every 2 seconds the stream status
mScheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
try {
if (mStreamId != null) {
checkStreamStatus();
}
} catch (IOException e) {
Log.e(TAG, null, e);
}
}
}, 0, 2, TimeUnit.SECONDS);
checkStreamStatus方法检查流状态，如果需要，还可以检查流健康状况（健康状况"GOOD"）：
public void checkStreamStatus() throws IOException {
YouTube.LiveStreams.List livestreamRequest = youtube.liveStreams().list("status");
livestreamRequest.setId(mStreamId);
LiveStreamListResponse returnedListResponse = livestreamRequest.execute();
List < LiveStream > returnedList = returnedListResponse.getItems();
if (returnedList.size() == 1) {
LiveStream stream = returnedList.get(0);
Log.v(TAG, "the current stream status is : " + stream.getStatus().getStreamStatus());
if (stream.getStatus().getStreamStatus().equals("active")) {
Log.v(TAG, "start broadcasting now");
startEvent();
mScheduleTaskExecutor.shutdownNow();
}
}
}
这是一个完整的例子：
public class YoutubeTask extends AsyncTask < Void, Void, String > {
private final static String TAG = YoutubeTask.class.getSimpleName();
private ScheduledExecutorService mScheduleTaskExecutor;
private String mStreamId;
private String mBroadcastId;
private static YouTube youtube;
@Override
protected String doInBackground(Void...params) {
mScheduleTaskExecutor = Executors.newSingleThreadScheduledExecutor();
// Authorize the request.
Credential credential = new GoogleCredential().setAccessToken("...");
// This object is used to make YouTube Data API requests.
youtube = new YouTube.Builder(new NetHttpTransport(), new JacksonFactory(), credential)
.setApplicationName("youtube-cmdline-createbroadcast-sample").build();
createLiveEvent(youtube, "event name");
// check every 2 seconds the stream status
mScheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
try {
if (mStreamId != null) {
checkStreamStatus();
}
} catch (IOException e) {
Log.e(TAG, null, e);
}
}
}, 0, 2, TimeUnit.SECONDS);
return null;
}
public void createLiveEvent(YouTube youtube, String name) {
try {
LiveBroadcastSnippet broadcastSnippet = new LiveBroadcastSnippet();
broadcastSnippet.setTitle(name);
broadcastSnippet.setScheduledStartTime(new DateTime(new Date()));
LiveBroadcastContentDetails contentDetails = new LiveBroadcastContentDetails();
MonitorStreamInfo monitorStream = new MonitorStreamInfo();
monitorStream.setEnableMonitorStream(false);
contentDetails.setMonitorStream(monitorStream);
LiveBroadcastStatus status = new LiveBroadcastStatus();
status.setPrivacyStatus("public");
LiveBroadcast broadcast = new LiveBroadcast();
broadcast.setKind("youtube#liveBroadcast");
broadcast.setSnippet(broadcastSnippet);
broadcast.setStatus(status);
broadcast.setContentDetails(contentDetails);
YouTube.LiveBroadcasts.Insert liveBroadcastInsert = youtube
.liveBroadcasts().insert("snippet,status,contentDetails",
broadcast);
LiveBroadcast returnedBroadcast = liveBroadcastInsert.execute();
LiveStreamSnippet streamSnippet = new LiveStreamSnippet();
streamSnippet.setTitle(name);
CdnSettings cdn = new CdnSettings();
cdn.setFormat("240p");
cdn.setIngestionType("rtmp");
LiveStream stream = new LiveStream();
stream.setKind("youtube#liveStream");
stream.setSnippet(streamSnippet);
stream.setCdn(cdn);
// Create the insert request
YouTube.LiveStreams.Insert liveStreamInsert = youtube.liveStreams().insert("snippet,cdn", stream);
// Request is executed and inserted stream is returned
LiveStream returnedStream = liveStreamInsert.execute();
// Create the bind request
YouTube.LiveBroadcasts.Bind liveBroadcastBind = youtube.liveBroadcasts().bind(returnedBroadcast.getId(),
"id,contentDetails");
// Set stream id to bind
liveBroadcastBind.setStreamId(returnedStream.getId());
// Request is executed and bound broadcast is returned
liveBroadcastBind.execute();
// store stream Id & broadcast Id
mStreamId = returnedStream.getId();
mBroadcastId = returnedBroadcast.getId();
} catch (GoogleJsonResponseException e) {
Log.e(TAG, null, e);
} catch (IOException e) {
Log.e(TAG, null, e);
} catch (Throwable t) {
Log.e(TAG, null, t);
}
}
public void checkStreamStatus() throws IOException {
YouTube.LiveStreams.List livestreamRequest = youtube.liveStreams().list("status");
livestreamRequest.setId(mStreamId);
LiveStreamListResponse returnedListResponse = livestreamRequest.execute();
List < LiveStream > returnedList = returnedListResponse.getItems();
if (returnedList.size() == 1) {
LiveStream stream = returnedList.get(0);
Log.v(TAG, "the current stream status is : " + stream.getStatus().getStreamStatus());
if (stream.getStatus().getStreamStatus().equals("active")) {
Log.v(TAG, "start broadcasting now");
startEvent();
mScheduleTaskExecutor.shutdownNow();
}
}
}
public void startEvent() throws IOException {
YouTube.LiveBroadcasts.Transition transitionRequest = youtube.liveBroadcasts().transition(
"live", mBroadcastId, "status");
transitionRequest.execute();
}
}
使用new YoutubeTask().execute();
您可以使用范围为https://www.googleapis.com/auth/youtube的{{3}}获取的访问令牌直接对此进行测试。另外，为了测试流，我建议使用Android应用oauth playground来测试到Youtube的相机流，您可以直接将流名称XXXX-XXXX-XXXX-XXXX

几天前我面临类似的问题......这就是我所做的......
需要记住的要点：a）您可能会在API中收到比使用youtube事件门户网站的diff RTMP网址。
b）在广播转换到状态＆＃34; Live＆＃34;无论你是否能够“上线”＃34;或不。
现在发生错误403（流处于非活动状态）：
确保在呼叫＆＃34;转播广播＆＃34;之前向youtube发送帧/数据。 现在打电话给＆＃34; Broadcast.transition＆＃34;在差异线程上，线程暂停几秒钟（将数据发送到youtube可能需要一段时间）。
例如：
public static void startEvent（最终YouTube youtube，final String broadcastId） 抛出IOException {
Toast.makeText(getApplicationContext(),"This is first story",Toast.LENGTH_SHORT).show();
我希望这有帮助......
