Integrate Video Streaming Into Your C/C++ Application Using Nex Gen Media Server API
Recently I took a closer look at Nex Gen Media Server and their API framework. NGMS is a multi-purpose streaming server which supports some of the popular streaming protocols such as RTSP, RTMP, Apple's HTTP Live, and MPEG-2 Transport Stream. NGMS comes with transcoding support and is able to capture and reformat live video streams and adapt them to be received by another type of device, such as capturing an HD video feed and converting it to be received by an iPhone over 3g. My focus was to integrate the NGMS API to control the streaming features directly from my own C application. In this example I am using Ubuntu Linux 10.04.
Reading Files From The Linux Kernel Space (Module/Driver) (Fedora 14)
It seems like operations that communicate with userspace are really discouraged. And I am not arguing with that. Although it doesn't mean that they cannot be accomplished. A driver loads configuration that could be stored only on HDD. When MS Windows XP boots up it remembers that I have turned Bluetooth off so it is not powered on, unlike even the latest Linux (Fedora 14 at the moment of writing) – such functionality in many drivers was not implemented. When developer uses procfs or character devices there should be another software or script in boot sequence that is actually sending information from a file to particular device. After some time looking over the internet I have managed to write such module that reads a file.

An Explanation of Pointers (C++)
Pointers are basically the same as any other variable. However, what is different about them is that instead of containing actual data, they contain a pointer to the memory location where information can be found. This is a very important concept, and many programs and ideas rely on pointers as the basis of their design, linked lists for example.
