The objective here is to show how to replicate the essence of the Vuforia-VideoPlayback sample scene using the Vuforia prefabs and the drag and drop approach of Unity:
Create a new Unity project
Import the Vuforia video playback unity package
Create a new scene
Drag the ARCamera prefab into the Unity scene
Under the DataSetLoadBehaviour in the Inspector tick “Load Data Set StonesAndChips”, and the 'Activate' checkbox below this From '/Qualcomm AugmentedReality/Prefabs' drag the ImageTarget
prefab into the scene
For the Image Target select “StonesAndChips” as the dataset and the Image Target should change to the Stones texture From Vuforia Video Playback/Prefabs drag the Video prefab to be the
child of the Image Target
In the Inspector under “Video Playback Behaviour (Script)” set the path to 'VuforiaSizzleReel_1.m4v'
Drag the TrackableEventHandler from Scripts to the Image Target (this plays the video)
Remove the DefaultTrackableEventHandler script from the Image Target as it is not needed.
Autoplay works already, however tapping the video does not yet work. In order to fix this, simply create a VideoPlaybackController script, fill it with the code below, and then attach this to the ARCamera.
Unity - How do I play video from URL ? December 20, 2013 - 4:47am #1
The Vuforia VideoPlayback sample demonstrates how to play videos and to render them as an augmentation of your image targets (video on texture). The samples use video files that are stored in the assets directory. However, it is also possible to play videos that are streamed from a URL (e.g. from the internet). In the Unity sample, you can achieve this by:
selecting the one of the Image Targets in the Hierarchy view (in the Unity Editor) and explanding it to show the Video game object underneath (i.e. the child of the image target )
selecting the Video gameobject and change the Path variable in the Inspector view (under theVideoPlaybackBehaviour component), replacing the existing filename (e.g. VuforiaSizzleReel_1.m4v) with the URL of the video you want to play (e.g. http://my.org.com/my_videos/my_video.mp4).
Build and deploy the udated sample to your device
Note that some video URLs may not work; in particular,
the Web Server you
are connecting to must conforms to the http Live Streaming protocol; also, the URL must point to an actual video file (such as .mp4 or .m4v). Note: Youtube URLs generally do not work "as is" with the VP sample, as they don't point explicitly to a video file. To test this functionality, you can use this sample video: http://oneshot.qualcomm.com/webAR/content/strawberryfields_H264_AAC.mp4
Also note that there may be certain limitations depending on the specific OS (Android/iOS) and OS version you are using; please check this link:
VideoPlayback - What videos can I play on what platform ? March 10, 2013 - 5:13am #1
The Vuforia VideoPlayback sample is available for Android, iOS and Unity. However, depending on the specific platform used, certain restrictions may apply.
Android (native) Videos can be played on-texture (i.e. video is rendered as a texture attached to the trackable in 3D space) on devices running Android 4.0 (ICS) and above. On Android versions prior to 4.0 (i.e. on all 2.x and 3.X versions), videos can only be played infullscreen mode; the sample code already contains logic to automatically detect the Android version and to select fullscreen automatically if needed Videos can can also be streamed from a network URL (e.g. "http://myorg/myvideos/video.m4v"); on Android 4.0 and above, videos streamed from network can be played on-texture without problems or limitations (same as for local video files). For a list of supported video/audio file formats on Android, you can consult this page: http://developer.android.com/guide/appendix/media-formats.html
iOS (native) Videos can be played on-texture on any iOS version supported by Vuforia (no specific limitations).
However, videos that are streamed from a network URL can only be played in fullscreen mode on iOS. For a list of supported video/audio file formats on iOS, you can consult this page: http://developer.apple.com/library/ios/#documentation/miscellaneo us/conceptual/iphoneostechoverview/MediaLayer/MediaLayer.htm l
Unity In general, the same constraints as for Android or iOS apply, depending on the target build platform chosen. In addition, the fullscreen mode (as implemented in the sample) makes use of a specific API (Handheld.PlayFullscreenMovie) which is only available with the Unity PRO license (notavailable on Unity Android Basic / iOS Basic licenses).
