Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1] It is a low-latency algorithm based on delta PCM coding and YC G C O-R color space. [1] [2]
Reference frames are frames of a compressed video that are used to define future frames. As such, they are only used in inter-frame compression techniques. In older video encoding standards, such as MPEG-2, only one reference frame – the previous frame – was used for P-frames. Two reference frames (one past and one future) were used for B ...
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.
Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler -based GeForce 600 series in March 2012 (GT 610, GT620 and GT630 is Fermi Architecture).
It is bundled as part of the Epic Video Tools along with Epic Games Tools' previous video codec, Smacker video. It is a hybrid block-transform and wavelet codec using 16 different encoding techniques. The codec places emphasis on lower decoding requirements over other video codecs with specific optimizations for the different computer game ...
This software is commonly used for desktop recording, gameplay recording and video editing. Screencasting software is typically limited to streaming and recording desktop activity alone, in contrast with a software vision mixer, which has the capacity to mix and switch the output between various input streams.
Adaptive streaming overview Adaptive streaming in action. Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks.. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are based almost exclusively on HTTP, [1] and are designed to work efficiently over large ...
The name "Quick Sync" refers to the use case of quickly transcoding ("converting") a video from, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone, in situations where speed is more important than the best possible quality. Unlike video encoding on a CPU or a general-purpose GPU, Quick Sync is a dedicated ...
