x264 – H.264/MPEG-4 AVC implementation. x264 is not a codec (encoder/decoder); it is just an encoder (it cannot decode video). OpenH264 – H.264 baseline profile encoding and decoding OpenVVC [ 1 ] an VVC /H.266 Real Time - Decoder for Mac OS , Windows , Linux and Android and special Version of FFmpeg , [ 2 ] which was used for Ateme ...

The HEVC MainConcept SDK encoder was demonstrated at the IBC 2012 trade show. [8] [9] On September 9, 2012, ATEME demonstrated at the IBC 2012 trade show a HEVC encoder that encoded video with a resolution of 3840x2160p at 60 fps with an average bit rate of 15 Mbit/s. [10] [11] ATEME is planning to release their HEVC encoder in October 2013 ...
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.
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files.
The video sequences were encoded using the HM-10.0 HEVC encoder and the JM-18.4 H.264/MPEG-4 AVC encoder. The average bit rate reduction based on PSNR was 45% for inter frame video. In a video encoder comparison released in December 2013, the HM-10.0 HEVC encoder was compared with the x264 encoder (version r2334) and the VP9 encoder (version v1 ...
In a subjective quality comparison conducted in 2014 featuring the reference encoders for HEVC (HM 15.0), MPEG-4 AVC/H.264 (JM 18.6), and VP9 (libvpx 1.2.0 with preliminary VP9 support), VP9, like H.264, required about two times the bitrate to reach video quality comparable to HEVC, while with synthetic imagery VP9 was close to HEVC.

As the template compression methods shows, lossy video compression algorithms involve the steps: motion estimation (ME), discrete cosine transform (DCT), and entropy encoding (EC). AMD Video Code Engine (VCE) is a full hardware implementation of the video codec H.264/MPEG-4 AVC. It is capable of delivering 1080p at 60 frames/sec.
