    HEVC Video Extensions

    HEVC Video Extensions

    Play HEVC (H.265) encoded videos on Windows

    HEVC Video Extensions from Device Manufacturer is the official application for playing the HEVC (H.265) codec on Windows 10 and Windows 11. Microsoft offers two identical applications for playing this codec natively by hardware. The only difference between them is that one costs money and the other is free. The free one is included on new devices sold by big brands, like laptops that come with Windows pre-installed. These manufacturers don't have to pay to include the codec. ...

    AV1 AVIF

    AV1 AVIF

    AV1 Image File Format Specification - ISO-BMFF/HEIF derivative

    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...

    AudioCraft

    AudioCraft

    Audiocraft is a library for audio processing and generation

    ...It includes MusicGen for music generation conditioned on text (and optionally melody) and AudioGen for text-conditioned sound effects and environmental audio. Both models operate over discrete audio tokens produced by a neural codec (EnCodec), which acts like a tokenizer for waveforms and enables efficient sequence modeling. The repo provides inference scripts, checkpoints, and simple Python APIs so you can generate clips from prompts or incorporate the models into applications. It also contains training code and recipes, so researchers can fine-tune on custom data or explore new objectives without building infrastructure from scratch. ...

    AIOStreams

    AIOStreams

    One addon to rule them all

    ...Instead of juggling multiple add-ons, you point AIOStreams at them; it then queries, merges, de-duplicates, and re-ranks everything according to your rules. The project includes a powerful filtering and sorting engine—think conditions on resolution, codec, provider, cached status, seed count, and more—so power users can shape results precisely. It also provides a template-based formatter to control how streams are labeled in the UI, complete with live preview for quick iteration. Catalog controls extend the same idea to the home page: rename, reorder, hide, shuffle, and enhance posters from supported metadata sources to unify your browse experience. ...

    rav1e

    rav1e

    The fastest and safest AV1 encoder

    rav1e is an open-source implementation of an encoder for the AV1 video codec, developed in Rust (with some assembly) by the community around Xiph Foundation. Its design philosophy is to start from a correct, minimal, and fast AV1 encoder — sacrificing some encoding speed/efficiency of reference encoders in exchange for simplicity, stability, and compilability across platforms — and then gradually improve.

    Moshi

    Moshi

    A speech-text foundation model for real time dialogue

    Moshi is a speech-text foundation model and full-duplex spoken dialogue framework. It uses Mimi, a state-of-the-art streaming neural audio codec. Mimi processes 24 kHz audio, down to a 12.5 Hz representation with a bandwidth of 1.1 kbps, in a fully streaming manner (latency of 80ms, the frame size), yet performs better than existing, non-streaming, codecs like SpeechTokenizer (50 Hz, 4kbps), or SemantiCodec (50 Hz, 1.3kbps). Moshi models two streams of audio: one corresponds to Moshi, and the other one to the user. ...

    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines.

    Aeyae Remux

    Aeyae Remux

    GOP-based video editor (remuxer)

    ...Aeyae Remux can be used to stitch together files... within reason. Since it is only a remuxer -- stitched files must be of compatible format. This means stitched files must have the same audio/video codecs, and codec properties (width, height, sample rate, etc...). That said... Aeyae Remux currently doesn't check or enforce this restriction, so beware -- garbage input will likely produce garbage output. Linux binaries are provided as AppImage, built on Ubuntu 14.04. 8 GB of RAM (but more is better) is highly recommended if working with source files longer than 2 hours.

    Lyra

    A Very Low-Bitrate Codec for Speech Compression

    lyra is a neural audio codec designed to deliver intelligible, natural-sounding speech at extremely low bitrates, making real-time communication viable on constrained networks. It replaces hand-engineered codecs with learned models that capture speech characteristics more efficiently and reconstruct waveforms with a neural vocoder. The system targets mobile-class hardware, balancing latency and quality so it can run in real-time on phones.

    State-of-the-art deep learning based audio codec

    Encodec is a neural audio codec developed by Meta for high-fidelity, low-bitrate audio compression using end-to-end deep learning. Unlike traditional codecs (like MP3 or Opus), Encodec uses a learned quantizer and decoder to reconstruct complex waveforms with remarkable accuracy at bitrates as low as 1.5 kbps. It employs a convolutional encoder–decoder architecture trained with perceptual loss functions that optimize for human auditory quality rather than raw waveform distance. ...
