AV1 AVIF is the official specification and reference design for the AV1 Image File Format (AVIF), defining how AV1-encoded bitstreams are packaged into the HEIF container format (based on ISOBMFF) to produce AVIF files. The project outlines the syntax and semantics required for AVIF compliance, including support for multiple image profiles, color depths, chroma subsampling modes, HDR/WCG, alpha channels, animation/image sequences, and various color-space/bit-depth combinations — making AVIF...

CutterFF is a small program for UNIX (or Windows if compiled with MingW) for cutting videos using FFmpeg and GTK+. It is easy to use and fast, since it do not decode and encode the streams, instead it only copy them.

...LSD extends the existing native canonical media analysis with a Current A / Reference B comparison workflow. LSD performs native Matroska, WebM, MP4, M4V, MOV, AVI parsing and native XviD, AVC/H.264, HEVC/H.265, VVC/H.266, VP8/9 and AV1 bitstream analysis. It provides frame-level QP/DRF statistics, DRF distribution, GOP and I/P/B frame analysis, bitrate profiles, stream metadata, and detailed diagnostic reports. The application does not use FFmpeg, FFprobe, MediaInfo, or other external multimedia tools. Video files are read and analyzed without decoding, modification, or transcoding. ...

A simplest video encoder based on FFmpeg. It is based on VC 2010. It is suitable for beginner of FFmpeg. It encodes YUV420P data to H.264 bitstream. It only uses about 100 lines of code. Eacn line of source code is important. New developer of FFmpeg can learn FFmpeg's API through this software. It contains following project: simplest_ffmpeg_video_encoder: Simple Encoder. It uses libavcodec to encode video and uses libavformat to add container format to the video bitstream. ...

ces265 is a "High Efficiency Video Coding" (HEVC) software written in C++ with multi-threading support. This software compresses the raw video stream in YUV 4:2:0 planar format into HEVC 8.0 compatible bitstream. Help is taken from HM-8.0, HM-9.2 and x265 software while writing this software. The contributors of this software are: 1- Muhammad Usman Karim Khan (http://ces.itec.kit.edu/~khan/) 2- Muhammad Shafique (http://ces.itec.kit.edu/~shafique/) 3- Jörg Henkel (http://ces.itec.kit.edu/~henkel/)

XvBA Tools is a library and small tool suite for demonstrating use of AMD's XvBA (X-Video Bitstream acceleration) API.

Modifies a MPEG-4 ASP video (XviD, DivX) without re-encoding (change aspect ratio, edit userdata, remove packed bitstream, and change interlaced field order). Also Warns about compatibility problems with standalone Players.

P264Decoder is a free h.264 decoder. It support baseline profile and x264 base bitstream now. The initial p264decoder version is based on the uncompleted x264 decoder. website: http://p264decoder.zj.com

The H.264 VHDL core is a hardware implementation of the H.264 video compression algorithm. The core accepts up to the highest resolution HDTV video stream as input and outputs the encoded bitstream. Simple, fully synchronous design with low gate count.

A library providing a full implementation of MPEG-2 transport streams (ISO/IEC 13818-1 aka ITU-T Rec. H.222). Can read, write and edit transport streams. Code is generated from a XML description of the bitstream syntax. This may be extended to other multimedia file formats in the future.
