Hence a much lighter operating system is found in Angstrom. Angstrom is a much lighter operating system that proves faster while maintaining reliability. However, maximizing speed is essential camera quickcam 8.1.1 embedded video streaming and thus drives our decision to use Angstrom over Ubuntu. Ease of use and package availability are the main advantages Ubuntu harbors over Angstrom.

Ease of use would be a greater factor if we had to interface more regularly with the beagleboard. However, Angstrom software is by vast majority compatible on Ubuntu, despite the converse not being true. Thus with prior knowledge of software availability, the software development can be done almost exclusively on a local computer running Ubuntu despite running Angstrom on camera quickcam 8.1.1 BeagleBoard. This camera quickcam 8.1.1 creative solutions such as compiling from saved Team 17 binary files or cross-compiling from pre-configured files and hardware drivers available on larger package libraries.

Current technology renders even a single wireless camera quickcam 8.1.1 data stream unwieldy for most embedded systems. So long as video compression is available, the fastest, lightest operating system that will meet the requirements must be developed. Angstrom, though poorly documented in comparison to Ubuntu, is used frequently with the BeagleBoard-xM. Forum posters note this compatibility and address software-related concerns promptly. GStreamer Gstreamer is an open-source software suite for the development of media streaming applications in Linux.

Gstreamer programs are comprised of various elements, such as media input sources, format converters, encoders, camera quickcam 8.1.1, network transmitters, and more. These elements are arranged into a pipeline that can be used to transmit audio and video over a typical network.

In this project such a pipeline is used, and it is the same regardless of whether or not it is a wired or wireless network. For desktop applications, the CPU offers an adequate number of instructions per second to handle most media applications. One embedded devices, the CPU is insufficient to handle real time video encoding camera quickcam 8.1.1 itself.

The processor used in this project, the Texas Instruments DM, has hardware, in addition to the CPU, for video and digital signal processing. This hardware requires specially written software to be used camera quickcam 8.1.1 its full potential, which has been written by Texas Instruments.


The TI plugins for Gstreamer are available for Angstrom, and they give the BeagleBoard-xM camera quickcam 8.1.1 capability to encode video using the h camera quickcam 8.1.1 in real time. Using this special encoder plugin the BeagleBoard-xM was able to achieve 30 frames per second at standard definition resolution. These plugins enable the user to specify video and audio details such as compression format, source and sink location, video cropping, resolution, and bitrate, among others.Logitech digital camera quickcam driver Free Driver Download for Windows 10,8, 7, XP 3.
