PHP-FFmpeg/PHP-FFmpeg
PHP FFmpeg
PHP-FFmpeg es un wrapper orientado a objetos para ejecutar comandos binarios de FFmpeg dentro de aplicaciones PHP. Sirve como librería de procesamiento multimedia y kit de herramientas para transcodificar, recortar, fusionar y filtrar archivos de audio y vídeo a través de una interfaz programática estandarizada.
El proyecto proporciona drivers especializados para la manipulación de vídeo, edición de audio y extracción de metadatos multimedia. Estos drivers permiten aplicar filtros visuales, modificar tasas de muestreo de audio y sondear archivos multimedia para recuperar especificaciones técnicas y validar la integridad de los archivos.
La librería cubre una amplia gama de capacidades de procesamiento de medios, incluyendo conversión de formatos, sincronización de flujos y generación de formas de onda de audio. Admite tareas de edición de vídeo programática como la extracción de fotogramas, concatenación de medios y la orquestación de grafos de filtros complejos para componer múltiples fuentes multimedia.
Features
- FFmpeg Transcoders - Provides a comprehensive PHP wrapper for FFmpeg to automate media transcoding across different formats and codecs.
- Binary Wrappers - Provides a programmatic PHP API that wraps the external FFmpeg binary to execute media processing commands.
- Media Metadata Extraction - Extracts technical specifications, stream details, and duration from multimedia files for validation and organization.
- FFmpeg Wrappers - Provides an object-oriented PHP interface for executing FFmpeg binary commands for media processing.
- Filter Graph Applications - Orchestrates complex audio and video filter chains using FFmpeg's libavfilter syntax.
- Media Metadata Extractors - Probes multimedia files to retrieve technical specifications and validate file integrity.
- Multimedia Processing - Ships a comprehensive toolkit for transcoding, clipping, merging, and filtering media files.
- Media Transcoding - Transforms audio and video files between different containers, codecs, and bitrates.
- CLI Argument Builders - Constructs complex CLI arguments by mapping internal PHP configurations to structured FFmpeg flags and options.
- Child Process Execution - Spawns and manages external FFmpeg system processes to handle resource-intensive media encoding tasks.
- Audio Processing - Offers programmatic tools for modifying audio sample rates, updating metadata, and processing audio streams.
- Audio-Video Synchronization - Aligns audio and video streams by correcting timing delays to ensure perfect playback synchronization.
- Media Concatenators - Combines multiple audio or video files into a single output stream sequentially.
- Stream Manipulations - Allows programmatic control over media playback speed, duration, and overall stream quality.
- Filter-Based Compositing - Merges multiple video sources and creates collages through the orchestration of FFmpeg filter graphs.
- Audio Driver Abstractions - Implements a specialized audio editing driver to adjust sample rates and modify audio metadata.
- Video Stream Filter Chain Applications - Supports chaining video filters for operations like rotating, resizing, cropping, and watermarking.
- Video Clip Extraction - Enables cutting audio or video files at specific timecodes to produce shorter segments.
- Video Frame Extraction - Captures static images from video streams at specific timecodes.
- Video Editing - Automates video editing tasks such as cutting, trimming, rotating, and watermarking via programmatic controls.
- Video Manipulation Drivers - Provides a specialized video manipulation toolkit for applying filters, extracting frames, and modifying playback properties.
- Process Output Captures - Captures and parses standard output from FFmpeg to monitor transcoding progress and retrieve metadata.
- Interface-Based Decoupling - Utilizes PHP interfaces to decouple the library API from specific versions of the underlying FFmpeg binary.
- Email and Files - Wrapper for the FFmpeg video processing library.
