RxFFmpeg
RxFFmpeg es un framework multimedia y transcodificador de medios para Android basado en FFmpeg. Proporciona un conjunto de herramientas para la edición, transcodificación y procesamiento de audio y video en dispositivos Android.
El framework integra un componente de reproducción de video para renderizar archivos locales y flujos de red con soporte para zoom y rotación. También incluye bibliotecas especializadas para la edición de video en Android, como recorte y empalme, y procesamiento de audio para mezclar pistas y modificar el tono de voz.
El proyecto cubre capacidades amplias de manipulación de medios, incluyendo la conversión de imágenes a video, la extracción de metadatos y la aplicación de efectos visuales como subtítulos y filtros. Soporta la separación de audio y video, así como la conversión de archivos multimedia entre diferentes formatos y códecs.
Features
- FFmpeg Wrappers - Provides a programmatic Android interface wrapping FFmpeg binaries for comprehensive media editing and transcoding.
- FFmpeg Native Wrappers - Wraps FFmpeg and FFprobe into platform-specific native libraries to expose media processing to the Android runtime.
- Command Synthesis - Constructs complex FFmpeg shell commands by mapping high-level editing requests into specific command-line flags.
- Android Media Playback - Renders local and online video streams on Android with support for rotation and zoom gestures.
- Audio Processing - Provides capabilities to trim, mix, and modify the pitch of audio tracks within multimedia files.
- Android Implementations - Provides Android-specific audio trimming, mixing, and pitch modification for video files.
- Mobile Processing Toolkits - Includes a toolkit for mixing audio tracks, changing voice pitch, and extracting audio from video on Android.
- Media Transcoding - Converts audio and video files between different formats, resolutions, and bitrates using optimized codecs.
- Multimedia Playback Components - A player for rendering local files, online videos, and live streams with support for zooming and rotation gestures.
- FFmpeg Transcoders - Uses FFmpeg as the underlying engine to convert media files between different formats and codecs.
- Video Editing - Provides tools to cut, crop, splice, and adjust playback speed or direction of video clips.
- Android Implementations - Provides tools for cutting, cropping, and splicing video clips specifically on Android devices.
- Android Multimedia Players - Implements a full-featured media player for Android supporting local files, network streams, zoom, and rotation.
- Asynchronous Task Execution - Provides mechanisms for executing long-running media transcoding tasks in the background with progress polling.
- Media Metadata Extraction - Retrieves detailed technical properties and attributes from audio and video media files.
- Image-to-Video Sequencing - Transforms static images into video files or decodes video frames back into individual images.
- Audio Track Extraction - Provides a utility to extract the audio track from a video file to create a standalone audio recording.
- Video Rendering Effects - Provides capabilities to apply filters, watermarks, and subtitles to video streams.
- Visual Overlays - Layers subtitles, filters, stickers, and GIF animations directly onto video streams.
- Third-Party Library Integration - Integrates external native libraries like x264 and fdk-aac into the Android project.
- Subprocess Command Execution - Implements a system to execute FFmpeg native binaries as asynchronous subprocesses with progress tracking.
- Task Status Polling - Tracks the completion percentage of media tasks by parsing the standard output of the processing engine.
