[iOS] Memory leak in GetPixels and GetPixels32



To Reproduce:

1. Open & deploy the attached project to iOS.
2. After run transfer the debug session to instruments profiler.
3. Observe that memory usage continues to grow until the app crashes due to 'memory pressure'.

This increase in memory usage is not visible in Xcode, it shows that it's only around 100-200mb at the time of crash.

    I got the same problem in Unity 4.6.5 for iOS project.
    Memory usage increases sooooon when calling webcamTexture.GetPixels32 () or webcamTexture.GetPixels()
    The problem seems exist for months, can you fix it ASAP?

    Have been working on project on Android (easier as I'm on PC) for about two months now, keeping up to date with the newest unity ver. So I was a bit shocked, when I had to show the project to the customer on iPad and it crashed after a few minuter, as the memory was leaking bad on IOS.
    Hope it'll be fixed soon..

    Thanks for a great product :)

    This simple code cause crash. Unity5.0.0f4 / IL2CPP Universal / iPhone5 ( iOS7)

    In Unity4.6.1(mono), this code works, and memory doesn't leak.

    void Update()
    if (webcamTexture != null && webcamTexture.isPlaying) {
    Color32[] pixels = webcamTexture.GetPixels32 (); // cause error

    > WARNING -> applicationDidReceiveMemoryWarning()

    I can confirm that WebCamTexture.didUpdateThisFrame is not working with iOS 8 in Unity 5.0.0.f4, as well.

    Also, it seems that "WebCamTexture.didUpdateThisFrame" is not working properly on iOS 8 with Unity 4.6.3p3.

    This is causing a crash in our iOS app after we access the camera function (both in iOS 8 and iOS 7).
