How to Compress Video Bitrate and Resolution in PHP Using FFMPEG Library Full Project For Beginners

Welcome folks today in this blog post we will be compressing video bitrate and resolution in php using ffmpeg library in browser. All the full source code of the application is shown below.

Get Started

In order to get started you need to make an index.html file and copy paste the following code

index.html

<link rel="stylesheet" type="text/css" href="bootstrap-darkly.min.css">
 
<div class="container" style="margin-top: 200px;">
    <div class="row">
        <div class="col-md-4 offset-md-4">
            <h1>Change bitrate</h1>
 
            <form method="POST" enctype="multipart/form-data" action="change-bitrate.php">
                <div class="form-group">
                    <label>Select video</label>
                    <input type="file" name="video" class="form-control" required="" accept="video/*">
                </div>
 
                <div class="form-group">
                    <label>Select bitrate</label>
                    <select name="bitrate" class="form-control">
                        <option value="350k">240p</option>
                        <option value="700k">360p</option>
                        <option value="1200k">480p</option>
                        <option value="2500k">720p</option>
                        <option value="5000k">1080p</option>
                    </select>
                </div>
 
                <input type="submit" name="change_bitrate" class="btn btn-info" value="Change bitrate">
            </form>
        </div>
    </div>
</div>

<h1>Change bitrate</h1>

<label>Select video</label>

</div>

<label>Select bitrate</label>

</select>

</div>

</form>

</div>

As you can see we allow the user to select the video file and then we have the select box to select the bitrate of the video file to compress the size of the video. And then we have the button to change the bitrate of the video. And then inside the form we are making the post request to the change-bitrate.php script. Now we need to make this php script as shown below

change-bitrate.php

<?php
 
$video = $_FILES["video"]["tmp_name"];
$bitrate = $_POST["bitrate"];
 
$command = "/usr/local/bin/ffmpeg -i $video -b:v $bitrate -bufsize $bitrate output.mp4";
system($command);
 
echo "File has been converted";

<?php

$video = $_FILES["video"]["tmp_name"];

$bitrate = $_POST["bitrate"];

$command = "/usr/local/bin/ffmpeg -i $video -b:v $bitrate -bufsize $bitrate output.mp4";

system($command);

echo "File has been converted";

As you can see inside the php script we are getting the video using the temporary path and then we are getting the value of the bitrate and then we are executing the ffmpeg command to change the bitrate of the video.

Changing Resolution of Video

Now we need to make the index.html file which will contain the form for changing the resolution of the video as shown below

index.html

<div class="container" style="margin-top: 50px; margin-bottom: 100px;">
    <div class="row">
        <div class="col-md-4 offset-md-4">
            <h1>Change resolution</h1>
 
            <form method="POST" enctype="multipart/form-data" action="change-resolution.php">
                <div class="form-group">
                    <label>Select video</label>
                    <input type="file" name="video" class="form-control" required="">
                </div>
 
                <div class="form-group">
                    <label>Select resolution</label>
                    <input type="text" name="resolution" class="form-control" placeholder="640x480">
                </div>
 
                <input type="submit" name="change_resolution" class="btn btn-info" value="Change resolution">
            </form>
        </div>
    </div>
</div>

<h1>Change resolution</h1>

<label>Select video</label>

</div>

<label>Select resolution</label>

</div>

</form>

</div>

Now we need to make the change-resolution.php script where we will be changing the resolution of the video

change-resolution.php

<?php
 
$video = $_FILES["video"]["tmp_name"];
$resolution = $_POST["resolution"];
 
$command = "/usr/local/bin/ffmpeg -i $video -s $resolution output2.mp4";
system($command);
 
echo "File has been converted";

<?php

$video = $_FILES["video"]["tmp_name"];

$resolution = $_POST["resolution"];

$command = "/usr/local/bin/ffmpeg -i $video -s $resolution output2.mp4";

system($command);

echo "File has been converted";
