AVCHDCoder for Linux
I started with the development of AVCHDCoder for Linux. I think there will be enough users so the time and effort I need to put into the project is righteous. If you are interested take a look at the following page: AVCHDCoder for Linux
First I will only focus on Ubuntu 11.04 but I think if you are experienced enough you can also get it to work on other distro's.
