Hi Alexey, thank you very much! I was in the meanwhile also optimizing the code with orc [1] and did simular changes than you did. The transform plugin I optimized with fixed-point arithemetic.I refactored the entire code since I want to move to ffmpeg with it eventually. I will release my new version on the project webpage [2] soon, and I will see how I can include your code. I am a bit busy at the moment, so be a bit patient please. I will probably come back to you as I read your patches...
