php 截取视频封面图

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.'">';



--code2
$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('./xxx_1544.mp4');



$ffprobe = FFMpeg\FFProbe::create();

$duration = $ffprobe
    ->format('./xxx1544.mp4') // extracts file informations
    ->get('duration');
//得到视频的长度，单位为秒

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.

<?php
declare(strict_types=1);

require_once './../vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create();

$video = $ffmpeg->open('intro.mp4');
$video ->filters()
->resize(new FFMpeg\Coordinate\Dimension(320, 240))
->synchronize();
$video->save(new FFMpeg\Format\Video\X264('aac'), 'minified-intro.mp4');

$video = $ffmpeg->open('minified-intro.mp4');
$video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(1))
->save('save.jpg');

–change dimension

$dimension = new FFMpeg\Coordinate\Dimension('-1', '720');

$mode = FFMpeg\Filters\Video\ResizeFilter::RESIZEMODE_SCALE_HEIGHT;
$video->filters()->resize($dimension, $mode)->synchronize();

— get mimension

$ffprobe = FFMpeg\FFProbe::create();
$video_dimensions = $ffprobe
    ->streams( $full_video_path )   // extracts streams informations
    ->videos()                      // filters video streams
    ->first()                       // returns the first video stream
    ->getDimensions();
