Vuforia Play video url from cloud metadata

Step 1:- Vuforia Cloud database we have to add one text file in metadata section. and in this text file, we have to add one video URL (Without streaming file means to say I can't able to play youtube URL because youtube is a streaming server. )

Step 2:- "onVuforiaUpdate" This function return metadata Url and cloud object name

NSString *video_url = [NSString stringWithFormat:@"%s",result->getMetaData()];

Step 3:- "VideoPlaybackEAGLView" In Eagle view i have again prepare Player with this new Video Url

[eaglView preparePlayers_st:video_url];

Step 4:- if we don't found any Url then we have to change media type

mediaState = ERROR

Step5:- VideoPlayerHelper class i have add one "load_with_URL" in this function i have pass url to play player in prepare function

Here i share with you code Step by step

1> VideoPlaybackViewController

}

Note:- this is automatic play the video , if you want to add play pause button then you have to changes in this line "playImmediately = NO"
