Can't Upload a Video to YouTube. Problem with Java Class files and service.se​tUserCrede​ntials?

12 views (last 30 days)
I am trying to upload a video to youtube from matlab using this spiffy code: http://www.mathworks.com/matlabcentral/fileexchange/19258-upload-a-video-to-youtube%E2%84%A2.
I updated the clientID and the developerKey. But I still get the same error at service.setUserCredentials(username, password). I am using a gmail account and password, which should be a valid login. I tried several and I still can't get this code to work. Any help would be appreciated.
My feeling is that I need use a different login class (GoogleService.setUserCredentials). And call these classes instead getAuthToken, setUserCredentials in GoogleAuthTokenFactory.
Here is the error message.
Java exception occurred: com.google.gdata.util.AuthenticationException: Error connecting with login URI
at com.google.gdata.client.GoogleAuthTokenFactory.getAuthToken(GoogleAuthTokenFactory.java:489)
at com.google.gdata.client.GoogleAuthTokenFactory.setUserCredentials(GoogleAuthTokenFactory.java:346)
at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:362)
at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:317)
at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:301)

There are several bugs with this code. The native cacerts file, developerKey, and clientID are all issues. The java archives also packaged with matlab might also be at fault. I was able to successfully upload videos to matlab by doing the following:
2) I wrote a small script to upload videos:
uploadmovie(moviefile,mystr,mycategory) % uploadmovie % uploadmovie automatically uploads a game movie to youtube.
% HISTORY: % Version 1.0, 2011-10-21.. commandline_str = ['google youtube post ' ... '--category ' mycategory.... ' --summary "' mystr '"'... ' "' movie_file '"'];
system(commandline_str);
This works very well. You have to do a few things. You still need to register your account to get a clientid and developerkey from google. Then enter put the clientid in your web browser. Google will ask you to confirm that this computer can remote access your google account. There a few more steps but it is pretty intuitive. Good luck! Let me know if this was helpful.
