Linux Wireless AP Configuration

March 3, 2016

Configuring wireless in Linux can be complex. A very common question is how does one configure an IEEE802.11 radio as an Access Point (AP) from the command line interface (CLI). This question is difficult to answer due to evolving wireless technologies. Several tools have been created to aid in configuring these devices, but are generally not user friendly or portable across operating systems (OS). For example, in the OpenWrt OS, the UCI System allows users to configure their wireless devices easily through the CLI. But because this tool is tightly integrated into OpenWrt, it is not easily portable to other …

Adaptive Bitrate Streaming using GStreamer

January 26, 2016

Gateworks’ SBCs are widely used for streaming audio and video over the network via Ethernet, 802.11 WiFi, or 4G LTE Cellular.Networks are dynamic, whether from network load, RF interference or signal strength thus throughput will vary requiring intelligent and flexible applications to adjust as necessary. Adaptive Bitrate Streaming is the concept of adjusting the quality of video and/or audio depending on the quality of the network connection or server load. This type of technology is widely implemented throughout technology today, evident in streaming services like Netflix and YouTube.

GStreamer Compositing for Streaming H.264 Video

December 2, 2015

Gateworks recently featured a blog in which 8 video cameras were connected to a Gateworks Ventana SBC and then displayed on a HDMI monitor. This is useful for localized applications. For remote applications there is another solution. Remote applications require streaming the multiple video streams over the network (Ethernet or WiFi). For bandwidth efficiency, all camera inputs can be joined together into a single frame and then transmitted across the network. To join all the streams into a single frame, a software element of GStreamercalled a compositor is used. Older versions of the compositor relied on the CPU and caused …
