SAN19-107 Secure Data Path on Linux and NXP i.MX 8M
This session will present the various aspects of providing a Secure Data Path (SDP) implementation on Linux and NXP i.MX 8M. The implementation reuses some components from the SDP on Android (presented in HKG18-113):
- hardware memory protections,
- secure ION heaps for VPU and display,
- ION integration in OP-TEE and in DRM implementations.
On Linux, the implementation involves ION integration in OpenCDM and GStreamer.

**CANCELLED** SAN19-408 Holistic Audio Solution for Modern Embedded Devices
Audio is ubiquitous across a wide range of phone, tablet, notebook, speaker, headset, appliance, router, telematic, and other modern devices. To fully utilize the potential of dedicated audio subsystems on SoCs and other embedded devices with minimal engineering investment, an open, modularized, and extensible signal processing framework, with associated uniform APIs, is proposed for high performance or cost sensitive and power efficient audio applications. An extensible and modularized framework provides the flexibility, within the same architecture and codebase, to support a wide range of customizable features and capabilities without sacrificing the ability to scale up to higher performing, richer processing environments and also scale down to smaller, resource limited and cost sensitive environments. This presentation describes the key design principles of this advanced audio signal processing framework including programming interfaces and development workflow using open source community friendly SDK’s and use case design, configuration, and tuning applications

SAN19-501 WPEWebKit, the WebKit port for embedded platforms
WPEWebKit[1] is a WebKit flavor (also known as port) specially crafted for
embedded platforms and use-cases. During this talk I would present WPEWebKit's
architecture with a special emphasis on its multimedia backend based on
GStreamer[2] and implementing support for the MSE[3], EME[4], MediaCapabilities
specifications. I would also present a case study on how to successfully
integrate WPEWebKit on i.MX6 and i.MX8M platforms with the Cog[5] standalone
reference web-app container or within existing Qt5 applications, using the WPEQt
QML plugin.

SAN19-502 Optimizing “lean-forward” viewing experience on mobile platforms
Twitch is a live-streaming platform that creates interaction between broadcasters and audiences through chat messages on top of live video. Such a user-generated-content (UGC) interactive live streaming model offers a “lean-forward” experience to the viewers, which many of them find more interesting than the traditional linear TV’s “lean-backward” experience.

Although desktop browsers still account for the majority of Twitch’s traffic, mobile devices are emerging as very important client platforms, particularly in Twitch’s fastest-growing markets such as Asia and Latin America. On the other hand, we face a number of special challenges when trying to optimize the viewing experience on mobile devices. This talk will explain Twitch’s engineering effort on multiple aspects of the live video pipeline in order to achieve low latency, deploy new codec format, and handle the diversity of client devices.
