Generate preview image from Video file?
Solution #1 (Older) (not recommended)
Firstly install ffmpeg-php
project (http://ffmpeg-php.sourceforge.net/)
And then you can use of this simple code:
<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';
$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
$gd_image = $frame->toGDImage();
if ($gd_image) {
imagepng($gd_image, $thumbnail);
imagedestroy($gd_image);
echo '<img src="'.$thumbnail.'">';
}
}
?>
Description: This project use binary extension .so
file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg
or PHP
.
Solution #2 (Update 2018) (recommended)
Firstly install PHP-FFMpeg
project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg
)
And then you can use of this simple code:
<?php
require 'vendor/autoload.php';
$sec = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';
$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
echo '<img src="'.$thumbnail.'">';
Description: It's newer and more modern project and works with latest version of FFMpeg
and PHP
. Note that it's required to proc_open()
PHP function.
Two ways come to mind:
Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that
Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.
I recommend php-ffmpeg library.
Extracting image
You can extract a frame at any timecode using the
FFMpeg\Media\Video::frame
method.This code returns a
FFMpeg\Media\Frame
instance corresponding to the second 42. You can pass anyFFMpeg\Coordinate\TimeCode
as argument, see dedicated documentation below for more information.
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(42));
$frame->save('image.jpg');
If you want to extract multiple images from the video, you can use the following filter:
$video
->filters()
->extractMultipleFrames(FFMpeg\Filters\Video\ExtractMultipleFramesFilter::FRAMERATE_EVERY_10SEC, '/path/to/destination/folder/')
->synchronize();
$video
->save(new FFMpeg\Format\Video\X264(), '/path/to/new/file');
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:
$frameFileType = 'jpg'; // either 'jpg', 'jpeg' or 'png'
$filter = new ExtractMultipleFramesFilter($frameRate, $destinationFolder);
$filter->setFrameFileType($frameFileType);
$video->addFilter($filter);
