To connect FFmpeg with CodeIgniter, you will first need to have FFmpeg installed on your server. Once FFmpeg is installed, you can use the PHP exec() function to execute FFmpeg commands within your CodeIgniter application.

Here is a basic example of how to connect FFmpeg with CodeIgniter:

1. Install FFmpeg on your server: Follow the instructions on the FFmpeg website to install FFmpeg on your server.
2. Create a new CodeIgniter controller or model: Create a new controller or model file in your CodeIgniter application where you will be working with FFmpeg.
3. Use the exec() function to run FFmpeg commands: In your controller or model file, use the PHP exec() function to run FFmpeg commands. For example, you can use the following code to convert a video file to a different format:

1
2
3
4
5

$videoFilePath = 'path/to/your/video/file.mp4';
$outputFilePath = 'path/to/save/output/file.avi';

$ffmpegCommand = 'ffmpeg -i ' . $videoFilePath . ' ' . $outputFilePath;
exec($ffmpegCommand);

1. Handling errors: It is important to handle errors when using the exec() function to run FFmpeg commands. You can use the following code to check if the command was executed successfully:

1
2
3
4
5
6
7
8

$output = [];
$returnValue = 0;
exec($ffmpegCommand, $output, $returnValue);

if ($returnValue !== 0) {
    // Handle error
    // Log the output for debugging
}

1. Test the FFmpeg command: Once you have written the code to run FFmpeg commands in your CodeIgniter application, test it by running the controller or model file in your browser.

By following these steps, you can connect FFmpeg with CodeIgniter and use FFmpeg commands in your CodeIgniter application. Make sure to handle errors and sanitize input when using the exec() function to run commands on your server.
