If we manage to implement support for this format, it would likely be done in software. I don't think anyone can answer your other questions has no one have ever implemented this, hence measure performance. > > Would it be possible to get access to machine with IPU3, or would > there be someone willing to test libv4l2 patches? > > Thanks and best regards, > > > Pavel
