dovi_tool is a command-line utility written in Rust that provides a comprehensive set of tools for working with Dolby Vision metadata in video streams. It is designed to analyze, edit, and generate dynamic metadata used in high dynamic range video formats. The tool allows users to extract, inject, and modify RPU data, which controls how Dolby Vision content is displayed on compatible devices. 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. ...

...The library is designed for precise media manipulation, making it suitable for applications that require frame-level access or custom processing pipelines. PyAV integrates well with other Python libraries such as NumPy and Pillow, allowing seamless data transformation and analysis. It supports decoding, encoding, filtering, and resampling operations, covering a wide range of multimedia tasks. While powerful, it requires a solid understanding of FFmpeg concepts, as it prioritizes flexibility and control over abstraction. Overall, PyAV is a robust tool for developers building advanced video and audio processing systems in Python.

A stream implementation for Python that provides transparent base64 encoding and decoding of an underlying stream. This project is designed to develop a class, :class:`base64io.Base64IO`, that implements a streaming interface for Base64 encoding. Python has supported native Base64 encoding since version 2.4. However, there is no streaming interface for Base64 encoding, and none is available from the community. The legacy base64.encode and base64.decode interface lets you shuffle data between...

HTML5Media is a DITA Open Toolkit plugin and authoring UI that helps DITA content creators insert media such as video, audio and animated graphics into DITA source. When the DITA-OT outputs HTML to an HTML5-aware browser, the html5media plugin transforms the DITA media xrefs into HTML5-complient video, audio and canvas tags. The authoring UI helps writers preview media before insertion into DITA source. XML playlists provide a means of storage for media metadata. There are two zipped...
