And BTW: rawcam is open and the code is available on github. You just have to build it yourself
Off-topic but rawcam is available for free on tmo. It's just put at a high price on the Store for those who don't frequent TMO
The problem is not whether the camera hardware itself supports it or not. The problem is that the GStreamer element developed by Nokia does not have such features. GStreamer itself is a multimedia framework and is as good as the plugins developed are. Of course I can ditch those components, go deeper and implement the functionality by talking to the kernel driver but then I will be tied to harmattan and N9 because such features will not work in a similar way on other platforms. Is it a dead end? Short answer: No Long answer: I have plans to make the whole application support plugins. I just did not do it yet and I am not sure when I will do it
