An Object-Oriented library to convert video/audio files with FFmpeg / AVConv.

Check another amazing repo: PHP FFMpeg extras, you will find lots of Audio/Video formats there.

Your attention please

How to Install FFmpeg. However, avconv has different syntax than ffmpeg so your PHP scripts will need to know how to use avconv, not ffmpeg. How To Install FFmpeg In Linux. Install FFmpeg In Linux. Install FFmpeg on Arch Linux and its derivatives. Install Apache, MariaDB, PHP (LAMP) stack on Arch. Install FFmpeg and FFmpeg-PHP on Cpanel. FFMPEG is a fantastic tool if you’re developing a video content-based website like YouTube, Vimeo, or any other. This is an updated video tutorial showing where to get ffmpeg-php for Windows for PHP 5.3, how to install ffmpeg-php on your Windows Apache 2 server, and finally how to test/use the ffmpeg-php.

How this library works:

In this tutorial we will show you how to install FFmpeg and FFmpeg-PHP extension on CentOS, as well as some extra required by FFmpeg.

This library requires a working FFMpeg install. You will need both FFMpeg and FFProbe binaries to use it.Be sure that these binaries can be located with system PATH to get the benefit of the binary detection,otherwise you should have to explicitly give the binaries path on load.

For Windows users: Please find the binaries at http://ffmpeg.zeranoe.com/builds/.

Known issues:

Using rotate and resize will produce a corrupted output when usinglibav 0.8. The bug is fixed in version 9. This bug does notappear in latest ffmpeg version.

Installation

The recommended way to install PHP-FFMpeg is through Composer.

Basic Usage

Documentation

This documentation is an introduction to discover the API. It's recommendedto browse the source code as it is self-documented.

FFMpeg

FFMpegFFMpeg is the main object to use to manipulate medias. To build it,use the static FFMpegFFMpeg::create:

FFMpeg will autodetect ffmpeg and ffprobe binaries. If you want to give binarypaths explicitly, you can pass an array as configuration. A PsrLoggerLoggerInterfacecan also be passed to log binary executions.

Manipulate media

FFMpegFFMpeg creates media based on URIs. URIs could be either a pointer to alocal filesystem resource, an HTTP resource or any resource supported by FFmpeg.

Note: To list all supported resource type of your FFmpeg build, use the-protocols command:

To open a resource, use the FFMpegFFMpeg::open method.

Two types of media can be resolved: FFMpegMediaAudio and FFMpegMediaVideo.A third type, FFMpegMediaFrame, is available through videos.

Video

FFMpegMediaVideo can be transcoded, ie: change codec, isolate audio orvideo. Frames can be extracted.

Transcoding

You can transcode videos using the FFMpegMediaVideo:save method. You willpass a FFMpegFormatFormatInterface for that.

Please note that audio and video bitrate are set on the format.

Transcoding progress can be monitored in realtime, see Format documentationbelow for more information.

Extracting image

You can extract a frame at any timecode using the FFMpegMediaVideo::framemethod.

This code returns a FFMpegMediaFrame instance corresponding to the second 42.You can pass any FFMpegCoordinateTimeCode as argument, see dedicateddocumentation below for more information.

If you want to extract multiple images from the video, you can use the following filter:

Install Ffmpeg Mac

By default, this will save the frames as jpg images.

You are able to override this using setFrameFileType to save the frames in another format:

Clip

Cuts the video at a desired point. Use input seeking method. It is faster option than use filter clip.

The clip filter takes two parameters:

$start, an instance of FFMpegCoordinateTimeCode, specifies the start point of the clip
$duration, optional, an instance of FFMpegCoordinateTimeCode, specifies the duration of the clip

On clip you can apply same filters as on video. For example resizing filter.

Generate a waveform

You can generate a waveform of an audio file using the FFMpegMediaAudio::waveformmethod.

This code returns a FFMpegMediaWaveform instance.You can optionally pass dimensions as the first two arguments and an array of hex string colors for ffmpeg to use for the waveform, see dedicateddocumentation below for more information.

The output file MUST use the PNG extension.

If you want to get a waveform from a video, convert it in an audio file first.

Filters

You can apply filters on FFMpegMediaVideo with the FFMpegMediaVideo::addFiltermethod. Video accepts Audio and Video filters.

You can build your own filters and some are bundled in PHP-FFMpeg - they areaccessible through the FFMpegMediaVideo::filters method.

Filters are chainable

Rotate

Rotates a video to a given angle.

The $angle parameter must be one of the following constants :

FFMpegFiltersVideoRotateFilter::ROTATE_90: 90° clockwise
FFMpegFiltersVideoRotateFilter::ROTATE_180: 180°
FFMpegFiltersVideoRotateFilter::ROTATE_270: 90° counterclockwise

Resize

Resizes a video to a given size.

The resize filter takes three parameters:

$dimension, an instance of FFMpegCoordinateDimension
$mode, one of the constants FFMpegFiltersVideoResizeFilter::RESIZEMODE_* constants
$useStandards, a boolean to force the use of the nearest aspect ratio standard.

If you want a video in a non-standard ratio, you can use the padding filter to resize your video in the desired size, and wrap it into black bars.

The pad filter takes one parameter:

$dimension, an instance of FFMpegCoordinateDimension

Don't forget to save it afterwards.

Watermark

Watermark a video with a given image.

The watermark filter takes two parameters:

$watermarkPath, the path to your watermark file.$coordinates, an array defining how you want your watermark positioned. You can use relative positioning as demonstrated above or absolute as such:

Framerate

Changes the frame rate of the video.

The framerate filter takes two parameters:

$framerate, an instance of FFMpegCoordinateFramerate
$gop, a GOP value (integer)

Synchronize

Synchronizes audio and video.

Some containers may use a delay that results in desynchronized outputs. Thisfilter solves this issue.

Clip

Cuts the video at a desired point.

The clip filter takes two parameters:

$start, an instance of FFMpegCoordinateTimeCode, specifies the start point of the clip
$duration, optional, an instance of FFMpegCoordinateTimeCode, specifies the duration of the clip

Crop

Crops the video based on a width and height(a Point)

It takes two parameters:

$point, an instance of FFMpegCoordinatePoint, specifies the point to crop
$dimension, an instance of FFMpegCoordinateDimension, specifies the dimension of the output video

Audio

FFMpegMediaAudio can be transcoded too, ie: change codec, isolate audio orvideo. Frames can be extracted.

Transcoding

You can transcode audios using the FFMpegMediaAudio:save method. You willpass a FFMpegFormatFormatInterface for that.

Please note that audio kilobitrate is set on the audio format.

Transcoding progress can be monitored in realtime, see Format documentationbelow for more information.

Filters

You can apply filters on FFMpegMediaAudio with the FFMpegMediaAudio::addFiltermethod. It only accepts audio filters.

You can build your own filters and some are bundled in PHP-FFMpeg - they areaccessible through the FFMpegMediaAudio::filters method.
