OBS Studio is a free and open-source app for screencasting and live streaming.Written in C/C++ and built with Qt, OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via Real-Time Messaging Protocol (RTMP), HLS, SRT, RIST or WebRTC.
In revision 1.2, released in 2013, a new "Reduced Blanking Timing Version 2" mode was added which further reduces the horizontal blanking interval from 160 to 80 pixels, increases pixel clock precision from ±0.25 MHz to ±0.001 MHz, and adds the option for a 1000/1001 modifier for ATSC/NTSC video-optimized timing modes (e.g. 59.94 Hz instead ...
This page provides a comparison of notable screencasting software, used to record activities on the computer screen. This software is commonly used for desktop recording, gameplay recording and video editing.
Streamlabs Desktop (formerly Streamlabs OBS) is a free and open-source streaming software that is based on a fork of OBS Studio. Electron is used as the software framework for the user interface. [4] Streamlabs distributes the user's content over platforms such as Twitch, YouTube, and Facebook. [2] [5]
Compression is relatively low and the resulting file sizes are relatively large: A two-minutes-long screencast of a full HD screen (1920×1080) may take up 3.95 GiB on disk. [5] There is an option to encode the RGB value of every pixel, but the default is to use a YUV scheme for better compression. [ 6 ]
XSplit Broadcaster 1.2 became publicly available in January 2013. This update included enhancements in performance and support for new hardware devices such as Elgato Game Capture HD. [2] XSplit Broadcaster 1.3 was released in November 2013. This version contained security fixes to prevent login issues reported by some users.
Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time. It was developed by Vladimir Kajalin while working at Crytek and was used for the first time in 2007 by the video game Crysis , also developed by Crytek.
The Linux kernel can also use HPET as its clock source. The documentation of Red Hat MRG version 2 states that TSC is the preferred clock source due to its much lower overhead, but it uses HPET as a fallback. A benchmark in that environment for 10 million event counts found that TSC took about 0.6 seconds, HPET took slightly over 12 seconds ...
