Next, install the php-FFMpeg library via Composer with:

composer require php-FFMpeg/php-FFMpeg:~0.5

Setup and Usage

Include the autoload file in your PHP script:

require_once 'vendor/autoload.php';

Create an instance of FFMpeg\FFMpeg, optionally specifying paths if FFMpeg binaries aren’t in the system PATH:

use FFMpeg\FFMpeg;
$ff = FFMpeg::create(array(
    'binary' => '/path/to/FFMpeg',
    'ffprobe' => '/path/to/FFprobe'
));

Open a media file and perform operations, such as:

Transcoding: $video->save('output.mp4', new FFMpeg\Format\Video\X264());
Extracting a frame: $frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(5)); $frame->save('frame.jpg');
Clipping: $clip = $video->clip(FFMpeg\Coordinate\TimeCode::fromSeconds(10), FFMpeg\Coordinate\TimeCode::fromSeconds(20)); $clip->save('clip.mp4');

For more details, refer to the library’s documentation on GitHub.

Survey Note: Comprehensive Guide to Using php-FFMpeg/php-FFMpeg Version ~0.5

This note provides an in-depth exploration of using the “php-FFMpeg/php-FFMpeg” library, specifically version approximately 0.5, based on available information. It expands on the direct answer by including all relevant details from the research, ensuring a thorough understanding for users seeking to implement this PHP library for media manipulation.

Background and Context

The “php-FFMpeg/php-FFMpeg” library is a PHP wrapper for the FFMpeg binary, enabling object-oriented manipulation of video and audio files. It supports tasks such as transcoding, frame extraction, clipping, and more, making it valuable for developers working on media-related applications. The version specification “~0.5” indicates any version greater than or equal to 0.5 and less than 1.0, suggesting compatibility with older PHP versions, likely found in the 0.x branch of the repository.

Given the current date, March 3, 2025, and the library’s evolution, version 0.5 may be part of legacy support, with the main branch now requiring PHP 8.0 or higher. This note assumes the user is working within the constraints of this version, acknowledging potential differences in functionality compared to newer releases.

Installation Process

To begin, FFMpeg must be installed on the system, as the library relies on its binaries for operations. Installation methods vary by operating system:

Ubuntu: Use the command sudo apt-get install ffmpeg to install via the package manager.
macOS: Utilize Homebrew with brew install ffmpeg for a straightforward installation.
Windows: Download the FFMpeg binaries from this website and follow the provided instructions, ensuring the executables are accessible in the system PATH or specified manually.

Following FFMpeg installation, the php-FFMpeg library is installed via Composer, the PHP package manager. The command composer require php-FFMpeg/php-FFMpeg:~0.5 ensures the correct version is fetched. This process creates a vendor directory in the project, housing the library and its dependencies, with Composer managing autoloading for seamless integration.

Setup and Initialization

After installation, include the autoload file in your PHP script to enable access to the library’s classes:

require_once 'vendor/autoload.php';

Create an instance of FFMpeg\FFMpeg to start using the library. The creation method allows for configuration, particularly important if FFMpeg binaries are not in the system PATH:

use FFMpeg\FFMpeg;
$ff = FFMpeg::create(array(
    'timeout' => 0,
    'thread_count' => 12,
    'binary' => '/path/to/your/own/FFMpeg',
    'ffprobe' => '/path/to/your/own/FFprobe'
));

This configuration supports setting timeouts, thread counts, and explicit binary paths, enhancing flexibility for different system setups. The default setup looks for binaries in the PATH, but manual specification ensures compatibility, especially on custom environments.

Core Usage and Operations

The library provides a fluent, object-oriented interface for media manipulation. Begin by opening a media file:

$video = $ff->open('input.mp4');

This supports local filesystem paths, HTTP resources, and other FFMpeg-supported protocols, with a list of supported types available via the ffmpeg -protocols command.

Transcoding

Transcoding involves converting media to different formats. Use the save method with a format instance:

$format = new FFMpeg\Format\Video\X264();
$video->save('output.mp4', $format);

The X264 format is one example; the library supports various video and audio formats, implementable via FFMpeg\Format\FormatInterface, with specific interfaces like VideoInterface and AudioInterface for respective media types.

Frame Extraction

Extracting frames is useful for thumbnails or analysis. The following code extracts a frame at 5 seconds:

$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(5));
$frame->save('frame.jpg');

The TimeCode class, part of FFMpeg\Coordinate, ensures precise timing, with options for accuracy in image extraction.

Clipping

To clip a portion of the video, specify start and end times:

$clip = $video->clip(FFMpeg\Coordinate\TimeCode::fromSeconds(10), FFMpeg\Coordinate\TimeCode::fromSeconds(20));
$clip->save('clip.mp4');

This creates a new video segment, maintaining the original quality and format, with the ability to apply additional filters if needed.

Advanced Features and Considerations

The library supports additional features, as outlined in the documentation:

Audio Manipulation: Similar to video, audio can be transcoded with FFMpeg\Media\Audio::save, applying filters, adding metadata, and resampling.
GIF Creation: Animated GIFs can be saved using FFMpeg\Media\Gif::save, with optional duration parameters.
Concatenation: Combine multiple media files using FFMpeg\Media\Concatenate::saveFromSameCodecs for same codecs or saveFromDifferentCodecs for varied codecs, with resources for further reading at this link, this link, and this link.
Advanced Media Handling: Supports multiple inputs/outputs with -filter_complex, useful for complex filtering and mapping, with built-in filter support.
Metadata Extraction: Use FFMpeg\FFProbe::create for metadata, validating files with FFMpeg\FFProbe::isValid (available since v0.10.0, noting version 0.5 may lack this).

Coordinates, such as FFMpeg\Coordinate\AspectRatio, Dimension, FrameRate, Point (dynamic since v0.10.0), and TimeCode, provide precise control over media properties, though some features like dynamic points may not be available in version 0.5.

Version-Specific Notes

Given the “~0.5” specification, the library likely aligns with the 0.x branch, supporting older PHP versions. The GitHub repository indicates PHP 8.0 or higher for the main branch, with 0.x for legacy support. However, exact version 0.5 details were not explicitly found in releases, suggesting it may be part of commit history or branch commits. Users should verify compatibility, as newer features like certain coordinate types (e.g., dynamic points) may require versions beyond 0.5.

Documentation and Further Reading

While the Read the Docs page (Read the Docs) appeared empty, the GitHub repository (GitHub) contains comprehensive documentation within the README, covering API usage, formats, and examples. This is the primary resource for version 0.5, given the lack of specific online documentation for this legacy version.
