This is a blog post I wrote 6 months ago, and my life got too busy to finish it off, finish testing the code, improving the text. So I’m publishing this now, warts and all. There are probably bugs. There are bits that I could explain better – but I don’t have time. Note that the code is ripped from apps where I ACTUALLY USED IT – so I know it does work, and works well!
In brief:
- Using different “sources” of textures in OpenGL, not just images!
- Using CALayer’s as a source — allows for video in 3D!
- Using “Video straight from the video decoding chip” as a source – faster video!
