问题 What is the best way to record the mac screen with cocoa? I know there are many examples at the apple developer reference library. SonOfGrab explain how to capture the screen with quartz but also that it isn't enough fast to use it to grab many frames every second. OpenGLScreenSnapshot has same results but it isn't fast, too. OpenGLScreenCapture seems to be the best way to do it but XCode prompts me many errors because it's made for 10.4 and it requires old Quicktime commands I think they

问题 I am using FMOD to play some sounds and I would like to save the resulting mix to the disk. I have been trying the system->recordStart(0, sound, true) path, but that saves the microphone input of the device. In some way, I would like to redirect the speakers output to the disk Thank you Marc 回答1: To redirect everything that would go to the speakers to disk simply use the function System::setOutput and pass in a value of FMOD_OUTPUTTYPE_WAVWRITER. Make sure you call this function before you
