The release of the Linux distribution OpenIPC 2.1 has been published, designed for use in CCTV cameras instead of standard firmware, most of which cease to be updated by manufacturers over time. The release is positioned as experimental and, unlike the stable branch, is built not on the basis of the OpenWRT package base, but using buildroot. Project developments are distributed under the MIT license. Firmware images are prepared for IP cameras based on Hisilicon Hi35xx, SigmaStar SSC335, XiongmaiTech XM510 and XM530 chips.
The proposed firmware provides such functions as support for hardware motion detectors, native implementation of the RTSP protocol for distributing video from one camera to more than 10 clients simultaneously, the ability to use hardware support for h264 / h265 codecs, support for audio with a sampling rate of up to 96KHz, the ability to transcode JPEG images on the fly for interlaced loading (progressive) and support for the Adobe DNG RAW format, which allows solving problems of computational photography.
The main differences between the new version and the previous version based on OpenWRT:
- In addition to SoC HiSilicon, which is used in 60% of Chinese cameras on the domestic market, support for cameras based on SigmaStar and Xiongmai chips is announced.
- Added support for the HLS (HTTP Live Streaming) protocol, with which you can organize the broadcast of video from the camera to the browser without using an intermediate server.
- The OSD interface (on screen display) supports the output of Unicode characters, including for displaying data in Russian.
- Added support for the NETIP protocol (DVRIP), developed to control Chinese cameras. The specified protocol can be used to update cameras.
