Abstract

This talk describes our in-race-car video camera hardware and the open-source software that underpins our sub 200ms Glass to Glass streaming.

We will discuss interfacing to V4l2 (in various modes) from memory safe languages (that aren’t C) and also the problems and advantages of accessing a chip specific encoder API.

 I will have a solid grumble about the increasing complexity and opacity of the linux media APIs and a moan about how much I miss Plan9 style thinking.

We will use examples from the following open source projects (among others) https://github.com/pipe/whipi https://github.com/pipe/v4l2Reader https://github.com/steely-glint/PhonoSDK

Tim Panton

Tim is the CTO at pi.pe GmBH – who license a cleanroom webRTC stack to connected camera makers (e.g. baby monitors, race cars etc). He has been doing webRTC since before it was a thing, writing code, fixing bugs, listening to people and contributing to open standards (IETF + W3c) and opensource protocols (SNMP, SRTP,ICE, SCTP etc).

His earlier projects range from management code for ESA’s Infrared space telescope, an internet vulnerability scanner and an app providing video-calling for pets.
