VideoTexture Crashes iPad

Question

I'm running a video texture in Away3d in an Adobe Air app which runs fine on desktop and Android, however on iOS it crashes as soon as it tests for VideoTexture support

I create the video as such

 sphereGeometry = new SphereGeometry(5000, 64, 48);
        panoTexture2DBase = new NativeVideoTexture(Model.config.getAssetUrl(Model.currentScene.video), true, true);

        panoTexture2DBase.addEventListener(NativeVideoTexture.VIDEO_START,function(e:Event =null){setTimeout(onVideoStart,1000)});
        panoTextureMaterial = new TextureMaterial(panoTexture2DBase, false, false, false);

        panoVideoMesh = new Mesh(sphereGeometry, panoTextureMaterial);
        panoVideoMesh.scaleX *= -1;

        panoVideoMesh.rotate(Vector3D.Y_AXIS,-90);

        scene.addChild(panoVideoMesh);
        view.render();

        panoTexture2DBase.player.pause();

And the iPad appears to crash as soon as it plays

            _player.play();

In NativeVideoClass

Does anyone know how to stop the iPad crashing when I try and use VideoTexture or is this doomed to failiure?

This is the Air 21.

I've tried taking the video out of Away3d and into Starling. I've changed the codecs and managed to get it running in Starling.

The same video is still crashing in Away3D tho. It's when it's gets added to the stage.

I'm also getting NetStream.Play.Failed in the netstats event before it fails.

Which version of Air? Away3d? Have you tried a non-Away3d (using Stage3D api directly) based VideoTexture to see if it is a Air version "?" runtime bug on iOS? Tried other versions of Air? — SushiHangover, Mar 29 '16 at 09:16
Did you try a video file (mp4) that has been known to play fine on iOS? Or record a short test clip with iPad camera and try that as a video texture. This issue could be anything from video's settings to a bad line of code that iPad doesn't like. Also `Exception Message` tells you the limit on resource usage per app was **exceeded**. It is `150 per sec` but your crashed app gives `1617 per sec` for over 300 secs (5 mins) of usage... So check into why the big memory spike once your video texture is involved. — VC.One, Mar 29 '16 at 13:20
Yes it's Air 21. I'll try other versions of Air and try some other videos - and try to work out what the memory spike is about if it's not just trying to load a video. — beek, Mar 29 '16 at 21:15
Was your Starling test equal to the Away3D scene? Like are they both one sphere with an MP4 video texture, and you're saying Starling works whilst Away3D crashes when you do that? So you changed the codecs from what to what? In your video editor/converter, re-export the MP4 file containing H.264 video & choose to encode at a "Baseline" profile during file save settings. Try a smaller resolution if still problems. Try enable / disable hardware acceleration in your app settings.. — VC.One, Mar 31 '16 at 01:23
