...It also supports demuxing and muxing HEVC streams, enabling manipulation of enhancement layers and metadata within video files. dovi_tool is widely used in advanced video encoding workflows where precise control over HDR metadata is required. Its modular design includes multiple subcommands that handle different aspects of processing, from inspection to transformation. Overall, it serves as a powerful utility for professionals working with Dolby Vision video pipelines.

...The API is straightforward, allowing applications to integrate AVIF support natively — creating, decoding, compressing, or decompressing images programmatically. Recent developments have added experimental support for HDR gain maps, improved color-space handling (including wide color gamut and high bit depth), and better quality tuning modes for encoding, making libavif a cutting-edge tool for high-quality image compression.

...It enhances standard FFmpeg functionality by adding patches, fixes, and optimizations that improve compatibility and playback reliability in streaming environments. The project focuses on features that directly benefit media server use cases, such as better HDR and Dolby Vision handling, stable hardware acceleration, and consistent transcoding behavior. It is designed to integrate seamlessly with Jellyfin, ensuring that media is processed efficiently for streaming across different devices. The fork also includes backported fixes and targeted improvements that may not yet be available in upstream FFmpeg. ...

Flyleaf is a high-performance media playback engine for .NET applications that provides advanced video and audio playback capabilities using FFmpeg and hardware acceleration. It is designed to deliver smooth playback for high-resolution content, including 4K and HDR video. The framework includes a customizable player interface and supports integration into desktop applications built with WPF or other .NET UI frameworks. Flyleaf offers features such as subtitle rendering, audio track selection, and playback controls for a complete media experience. It also includes advanced buffering and synchronization mechanisms to ensure stable playback under varying conditions. ...

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 versatile, modern image format suitable for both simple photos and advanced imagery needing high fidelity. The specification ensures interoperability across encoders and decoders, providing guidelines so that images created by any compliant AVIF encoder can be reliably decoded by compliant decoders. ...

...While mpv strives for minimalism and provides no real GUI, it has a small controller on top of the video for basic control. mpv has an OpenGL, Vulkan, and D3D11 based video output that is capable of many features loved by videophiles, such as video scaling with popular high quality algorithms, color management, frame timing, interpolation, HDR, and more. mpv can leverage most hardware decoding APIs on all platforms. Hardware decoding can be enabled at runtime on demand. A straightforward C API was designed from the ground up to make mpv usable as a library and facilitate easy integration into other applications. mpv is under active development, focusing on code refactoring and cleanups.

...This player provides several performance options to enable adequate video playback on slow hardware: * skip loop filter * skip non-reference frames * skip color converter * reduce playback speed to accommodate slow video decoding This player supports playback of HDR video on non-HDR displays: * colorspace transform to BT.709 colorspace via an auto-generated 3D LUT * tone mapping from HDR to SDR (BT. 709) This player supports playback of MPEG-TS files containing multiple programs, timeline anomalies, and codec changes. Linux binaries are provided as AppImage, built on Ubuntu 14.04.

downkyi is an open-source downloader for Bilibili videos. It features a clean UI, QR-code login, batch downloads, support for 8K, HDR, Dolby Vision, audio/video extraction, watermark removal, and subtitle/danmaku retrieval. It leverages aria2c for multi-threaded downloading and FFmpeg for muxing and processing.

...The software is known for its simple, classic interface inspired by early Windows Media Player versions while still offering advanced playback capabilities. It includes support for modern codecs such as H.264, HEVC, and AV1, as well as features like subtitle rendering, HDR playback, and hardware acceleration. MPC-HC also allows extensive customization through external filters and playback settings, making it flexible for both casual users and advanced configurations. Despite its discontinuation as an official project, it remains widely used and maintained through community forks and integrations in codec packs.

This project provides realtime implementations of popular HDR tone mapping operators on GeForce 8800 GPUs using the CUDA programming environment.
