Stateless V4L2 Video Encoding - Andrzej Pietrasiewicz, Collabora Andrzej will start his talk from explaining the difference between stateful and stateless video codecs. He will outline the implications of each approach and highlight the benefits of the stateless approach. Andrzej will also share his experience with a particular VP8 stateless encoder integrated peripheral and talk about the currently available Open Source userspace software for stateless VP8 encoding, as well as his work on the corresponding upstream kernel driver. Having described this background Andrzej will discuss the proposed encoding uAPI and the prospects of new hardware implementing stateless VP8 encoding. He will also explain what rate control is and share the idea of how it can be implemented for stateless video encoders. The talk will conclude with a review of possible future directions for stateless video encoding in Linux. ...more
