Learn how to leverage Go's standard library abstractions to interact with hardware drivers and capture video streams in real-time. Discover techniques for issuing direct I/O calls to attached devices using the syscall package, and gain insights into working with the Linux userspace video API (V4L2) to control video hardware. Understand the process of building webcam programs that capture and stream image data in real-time. Delve into the intricacies of properly mapping and sharing data between Go programs and drivers to ensure kernel compatibility. This 31-minute presentation offers valuable knowledge for developers interested in expanding their Go programming skills into the realm of system-level video capture and processing.
