4K HEVC video processing with GPU optimization on Jetson TX1

Learn how to capture and process 4K video (HEVC encoding, scaling, mixing) on the TX1 and how to integrate the powerful GPU for complex tasks. 4K video previously required custom hardware or high-performance desktop processors. The heterogeneous system architecture of the TX1 allows to process these tasks in a single chip. The main challenges lie in the optimal utilization of the different hardware resources of the TX1 (CPU, GPU, dedicated hardware blocks) and in the software frameworks. Variants are discussed and bottlenecks identified. The interaction between hardware and software is shown. Simple capturing and displaying 4K video can be achieved using existing out-of-the-box methods. However, GPU based enhancements were developed and integrated for realtime scaling and video mixing
