Daala – Experimental Video codec which was under development by the Xiph.Org Foundation and finally merged into AV1. Thor – Experimental royalty free video codec which was under development by Cisco Systems, and merged technologies into AV1. Turing – A High Efficiency Video Coding (HEVC/H.265) encoder implemented by BBC Research.
K-Lite Mega Codec Pack was chosen as a Softpedia Pick. [15] Softpedia also reported K-Lite Codec Pack 5.2 Full, K-Lite Codec Pack Full 5.2 Update, and K-Lite Codec Pack 2.7 64-bit Edition have been downloaded a combined total of 1,452,750 times up until this date, and have received a user rating of 4.3 out of 5 from 2,082 users.
HEVC was designed to substantially improve coding efficiency compared with H.264/MPEG-4 AVC HP, i.e. to reduce bitrate requirements by half with comparable image quality, at the expense of increased computational complexity. [13] HEVC was designed with the goal of allowing video content to have a data compression ratio of up to 1000:1. [133]
Free and open-source software portal; libavcodec is a free and open-source [4] library of codecs for encoding and decoding video and audio data. [5]libavcodec is an integral part of many open-source multimedia applications and frameworks.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
On September 6, 2013, Thomson Video Networks demonstrated a trial of the HEVC codec for ultra HD transmission, conducted by satellite transmission operator HISPASAT. [64] On September 11, 2013, NGCodec Inc. announced availability of free 4K HEVC/H.265 test clips. [65]
A codec comparison from 2015 found x265 to be a leading HEVC implementation measured by SSIM metric. [16] In August 2016, Netflix published a comparison of x264, VP9, and x265 using video clips from 500 movies and TV shows using 6 different quality metrics and found that both VP9 and x265 have 40%–50% better quality at 1080p than x264.
