Linaro RDK with GStreamer-V4L2 video accelerator and Freedreno graphics overlay

Posted by Charbax – March 14, 2017

The Linaro Digital Home Group (LHG) has extensive experience working with the Comcast RDK. LHG has been instrumental in leading open source initiatives in the RDK. At Linaro Connect (BUD17), the LHG Director, Mark Gregotski, along with 2 Comcast assignee engineers (Siva Patchaiperumal and Kalyan Nagabhirava) are demonstrating a port of the RDK to the Qualcomm 96Boards Dragonboard 410c. This demo shows the RDK media framework taking advantage of the GStreamer-V4L2 support provided by the DBD410C to use the hardware video decoder. The HD video is scaled and then a rotating triangle is overlaid using the open source Freedreno graphics support available with DB410C. The demo shows smooth video playback without any stuttering with smooth graphics overlay. Since the video decode is offloaded to the video hardware, the CPU is not heavily loaded.
