PHP-FFmpeg/PHP-FFmpeg
PHP FFmpeg
PHP-FFmpeg is an object-oriented wrapper for executing FFmpeg binary commands within PHP applications. It serves as a multimedia processing library and toolkit for transcoding, clipping, merging, and filtering audio and video files through a standardized programmatic interface.
The project provides specialized drivers for video manipulation, audio editing, and media metadata extraction. These drivers allow for the application of visual filters, the modification of audio sample rates, and the probing of multimedia files to retrieve technical specifications and validate file integrity.
The library covers a broad range of media processing capabilities, including format conversion, stream synchronization, and the generation of audio waveforms. It supports programmatic video editing tasks such as frame extraction, media concatenation, and the orchestration of complex filter graphs for compositing multiple media sources.
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.
