Hi, I just started exploring the AppGameKit engine a few days ago and I was curious about this: Is there currently any way to play videos (such as mp4 files) onto a sprite surface or to the background of my AppGameKit application? We plan on using the tier2 AppGameKit in our project.

Or is there plans for future releases to support video playback?

We would mostly be using it to play fullscreen videos in the background, behind our sprites. Previously in our Windows applications we used DirectShow for this, which worked great, but a simple solution in the AppGameKit would be very useful for us.

Thanks for making such an easy to use engine I really appreciate it guys.

No support for video playback at the moment, although it is something for us to consider for an update.

Strangely enough, I was going to post the same thing this morning. In my case, I think I'd just want full screen video for use in things like pre-rendered intro sequences and so-on.

But if there are options for displaying sprites on top the video that would great, as would 'video sprites' that could be resized and moved around the screen.

I think it's time for us T2 users to start checking our how to implement important functions not supported by AppGameKit like video playback, in app purchases, and post some examples...

hi guys i found this post it might be a start for someone to start investigating vid playback.

Quote: "Create an AVURLAsset with the URL of your video - which can be a local file URL if you like. Anything QuickTime can do is fine, so MOV or M4V in H.264 is probably the best source.

Query the asset for tracks of type AVMediaTypeVideo. You should get just one unless your source video has multiple camera angles of something like that, so just taking objectAtIndex:0 should give you the AVAssetTrack you want.

Use that to create an AVAssetReaderTrackOutput. Probably you want to specify kCVPixelFormatType_32BGRA.

Create an AVAssetReader using the asset; attach the asset reader track output as an output. And call startReading.

Henceforth you can call copyNextSampleBuffer on the track output to get new CMSampleBuffers, putting you in the same position as if you were taking input from the camera. So you can lock that to get at pixel contents and push those to OpenGL via Apple's BGRA extension."

Yes it would be nice to have. It would certainly help to add polish to a product. I would hope that it will be included as an update at some point in the future.
