As a new player in the GPU market, we have always attached great importance
to the participation of the open source community. And willing to feed back our
new features to the field of video hardware acceleration.

As a pioneer, these new features may only be supported by our hardware
at current
time. We are willing to provide some market selling devices for free
to community
accredited contributors for testing related functions.
