Irfan Sadiq

H M Irfan Sadiq was a Linux enthusiast as a graduate student. He started his career as an embedded system development engineer and has been working as an H.264 Decoder developer and optimizer for the VLIW architecture. He got an opportunity to work on multiple multimedia frameworks that are open source as well as proprietary. He tried to work in a start-up in the entirely different domain of web development. He has been working on OpenEmbedded and Yocto Project technologies since he joined Mentor Graphics as the technical lead back in 2010. He has been working on derivative technologies of Yocto Project and OpenEmbedded for quite some time now, spanning more than 4 years. He has also been working on various hardware platforms based on the ARM, PPC, and x86 architecture. The diverse nature of subsequent BSPs has challenges in the context of QA. One of the challenges was to keep the QA packages in one place in such a way that they could be applied to all different product/platform combinations. He addressed this by creating a Yocto Project-based layer for which he is a maintainer as well as a gatekeeper.

Selected solution

Since I already mentioned in the requirements that we have a popular multimedia framework available called GStreamer, we will go for it. This is not rocket science. We will enable it in our rootfs. Certainly, we will face issues. However, we will hit our heads against these issues and resolve them. The answer to our problems is in the form of plugins. This way, we will enable BeagleBone to capture the stream from the attached webcam and serve it over our network to the client side.

Host/server side (BeagleBone)

A webcam will be attached to BeagleBone, and it will stream what is captured. The following are some of the requirements:

  • v4l2src: This is a plugin for reading from Video4Linux2-based devices, which is the Video I/O API and driver framework. Using this, we will widen the choice of our capture devices. These plugins run in user space. They call kernel IOCTL to communicate with the underlying kernel space driver for particular sensors plugged in via the USB of BeagleBone...
