问题
For generate my code I modified the samples putted from google on gitHub.
All Goes ok and the video upload has no problem but now I need to put some annotations or a 'end screen' to my videos because I need to redirect users to my site after they have seen my 'video preview'.
So, the workflow is something like this:
1) The user inserts title and description from a jsp page.
2) When he clicks on the button the software take the credentials of the user stored in my db and then pass all the parameters to the method i posted below.
3) the class uploads the video to YouTube.
Now my question is: there is an easy way to 'attach' my links to the uploaded video?
I should use something like annotations, call-to-action or any kind of overlay message/button on the video area.
It doesn't matter if the overlay persists for all the video duration or it appears only at the end of the video.
I hope someone can help me! And i hope google will rewrites the documentation in a better way because i became crazy for implements YouTube's API.
This is a snippet of my source code:
public static void upload( String jsonString, String videoPath, String title , String description, String articleTags, HttpServletRequest request) {
// This OAuth 2.0 access scope allows an application to upload files
// to the authenticated user's YouTube channel, but doesn't allow
// other types of access.
List<String> scopes = Lists.newArrayList("https://www.googleapis.com/auth/youtube.upload");
try {
// Authorize the request.
JSONObject jsonObj = new JSONObject(jsonString);
GoogleCredential credential = new GoogleCredential.Builder()
.setClientSecrets(jsonObj.getString("client_id"), jsonObj.getString("client_secret"))
.setJsonFactory(Auth.JSON_FACTORY).setTransport(Auth.HTTP_TRANSPORT).build()
.setRefreshToken(jsonObj.getString("refresh_token")).setAccessToken(jsonObj.getString("access_token"));
// This object is used to make YouTube Data API requests.
youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, credential).setApplicationName("virtual-cms-video-upload").build();
System.out.println("Uploading: " + videoPath);
// Add extra information to the video before uploading.
Video videoObjectDefiningMetadata = new Video();
// Set the video to be publicly visible. This is the default
// setting. Other supporting settings are "unlisted" and "private."
VideoStatus status = new VideoStatus();
status.setPrivacyStatus("public");
videoObjectDefiningMetadata.setStatus(status);
// Most of the video's metadata is set on the VideoSnippet object.
VideoSnippet snippet = new VideoSnippet();
// This code uses a Calendar instance to create a unique name and
// description for test purposes so that you can easily upload
// multiple files. You should remove this code from your project
// and use your own standard names instead.
snippet.setTitle (title );
snippet.setDescription(description);
if( !articleTags.trim().equals("") ){
// Set the keyword tags that you want to associate with the video.
List<String> tags = new ArrayList<String>();
for(int i = 0; i < articleTags.split(",").length ; i++){
tags.add(articleTags);
}
snippet.setTags(tags);
// Add the completed snippet object to the video resource.
videoObjectDefiningMetadata.setSnippet(snippet);
}
//InputStreamContent mediaContent = new InputStreamContent(VIDEO_FILE_FORMAT,UploadYouTubeVideo.class.getClassLoader().getResourceAsStream(videoPath));
InputStreamContent mediaContent = new InputStreamContent(VIDEO_FILE_FORMAT,new java.io.FileInputStream(new File(videoPath)));
// Insert the video. The command sends three arguments. The first
// specifies which information the API request is setting and which
// information the API response should return. The second argument
// is the video resource that contains metadata about the new video.
// The third argument is the actual video content.
YouTube.Videos.Insert videoInsert = youtube.videos().insert("snippet,statistics,status", videoObjectDefiningMetadata, mediaContent);
// Set the upload type and add an event listener.
MediaHttpUploader uploader = videoInsert.getMediaHttpUploader();
// Indicate whether direct media upload is enabled. A value of
// "True" indicates that direct media upload is enabled and that
// the entire media content will be uploaded in a single request.
// A value of "False," which is the default, indicates that the
// request will use the resumable media upload protocol, which
// supports the ability to resume an upload operation after a
// network interruption or other transmission failure, saving
// time and bandwidth in the event of network failures.
uploader.setDirectUploadEnabled(false);
MediaHttpUploaderProgressListener progressListener = new MediaHttpUploaderProgressListener() {
public void progressChanged(MediaHttpUploader uploader) throws IOException {
switch (uploader.getUploadState()) {
case INITIATION_STARTED:
System.out.println("Initiation Started");
break;
case INITIATION_COMPLETE:
System.out.println("Initiation Completed");
break;
case MEDIA_IN_PROGRESS:
System.out.println("Upload in progress");
System.out.println("Upload percentage: " + uploader.getProgress());
break;
case MEDIA_COMPLETE:
System.out.println("Upload Completed!");
break;
case NOT_STARTED:
System.out.println("Upload Not Started!");
break;
}
}
};
uploader.setProgressListener(progressListener);
// Call the API and upload the video.
Video returnedVideo = videoInsert.execute();
// Print data about the newly inserted video from the API response.
System.out.println("\n================== Returned Video ==================\n");
System.out.println(" - Id : " + returnedVideo.getId() );
System.out.println(" - Title : " + returnedVideo.getSnippet().getTitle() );
System.out.println(" - Tags : " + returnedVideo.getSnippet().getTags() );
System.out.println(" - Privacy Status: " + returnedVideo.getStatus().getPrivacyStatus());
System.out.println(" - Video Count : " + returnedVideo.getStatistics().getViewCount());
} catch (Exception ex) {
System.err.println("Throwable: " + ex.getMessage());
ex.printStackTrace();
}
}

Unfortunately, it is not possible, nor will it ever be as far as i can tell.
Not being able to add annotations is an intended behaviour. See this link: https://issuetracker.google.com/issues/35166657 - Status: Won't Fix (Intended behavior)
Apparently the best alternative is InVideo Programming but i do not believe this is suitable for your purpose, unless it can be video specific.
