There is some work going on to pull frames from the Kernel, munge them (such as decode, flip), and push them back into the Kernel on a different device node: http://linuxtv.org/hg/~tmerle/v4l2_extension However, ideally there would be a standard V4L2 library that all applications would build upon that would provide a simple flip operation and possibly a config file like ALSA. But, in our current state every application needs to be modified to allow for a flip option.
