[YouTube-API] Re: Creating/Updating captions via Java API returns prolog error..

Hello Rucha,

 There's no way to do this for arbitrary videos. You can only retrieve caption tracks using the API for videos that belong to your authenticated account.

Hello Jeffrey,

Is there a similar way to retrieve already available caption track (generated by Google Voice Recognition) if we know the VIDEO_ID ?

Hello Rajesh,

 It's a coincidence, because I was just writing some new Java code to
handle caption track creation and I realized that the code you're
working from, which looks to be from YouTube Direct, isn't working
anymore. Here's a modified version of a portion of the code that
should now work:

  GDataRequest request = service.createInsertRequest(new
URL(captionsUrl)); // http://gdata.youtube.com/feeds/api/videos/VIDEOID/captions
  request.setHeader("Content-Language", languageCode); // languageCode
should be a ISO 639-1 two letter code
  request.setHeader("Content-Type", "application/
vnd.youtube.timedtext; charset=UTF-8");
  request.getRequestStream().write(bytes); // get the caption track's
UTF-8 bytes via whatever method is appropriate
  request.execute();

 I'll probably update the YouTube Direct codebase in the near future.
