I am using QC composition in application and need to read output
image from "Video Input". When I do it in method that is called by
NSTimer everything works fine, but when I try to execute this
method from CoreAudio IO proc, program runs for a few seconds and
crashes with NBTVSource has exited due to signal 10 (SIGBUS).
Here basically what I am trying to do:
The QCView is not thread-safe: it's running on the main thread and
you're trying to access it from the CoreAudio IO thread. Try using a
QCRenderer instead and make sure it's accessed exclusively on one
thread at a time.
