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...

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. ...

...It implements a subset of JPEG standard. Now the code contains JPEG decoder so if you decided to use nonstandard transform or entropy coding in encoder you still will be able to decode bitstream (provided that you keep the decoder in sync of course). Release 1.1 source code and Windows executables are on the download page. For the latest release code look into the repository in 'release-1-0' branch. The SSE2 inplementation is present in 'simd.0' branch in the repository.

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.

Flavor is a language developed for describing (in a formal way) any coded audio-visual or general multimedia bitstream. It comes with a translator for automatic generation of C++/Java code, which can be used to read/write/trace the described bitstream.
