How to use PHP for video file processing?
Video file processing is an essential part of modern network applications, which includes operations such as cropping, compression, transcoding, adding watermarks, and merging. PHP, a popular server-side programming language, can be used to handle these requirements. In this article, we will explain how to process video files using PHP.
- Install FFMPEG library
FFMPEG is a powerful open source library that can be used to process video and audio files. To use FFMPEG with PHP, you need to install it first.
Install using one of the following commands:
- Ubuntu system: sudo apt-get install ffmpeg
- CentOS system: sudo yum install ffmpeg
- Processing video files
The following are several common ways to use PHP to process video files:
(1) Compress video files
Use FFMPEG, you can compress video file size by changing video parameters. The following is a sample code in PHP:
$videoFile = "input.mp4"; //输入视频文件 $outputFile = "output.mp4"; //输出视频文件 $size = '320x240'; //视频分辨率 $bitrate = '256k'; //视频比特率 $cmd = "ffmpeg -i $videoFile -s $size -b:v $bitrate $outputFile"; exec($cmd);
The above code uses the ffmpeg command line program to compress the input video file input.mp4 into the output video file output.mp4. The video resolution is 320x240 and the video bit rate is 256k. .
(2) Crop video files
Using FFMPEG, you can crop the video to trim the unwanted parts. The following is a sample code in PHP:
$videoFile = "input.mp4"; //输入视频文件 $outputFile = "output.mp4"; //输出视频文件 $start = '00:00:10'; //开始时间 $duration = '00:00:05'; //持续时间 $cmd = "ffmpeg -i $videoFile -ss $start -t $duration -async 1 $outputFile"; exec($cmd);
The above code uses the ffmpeg command line program to crop the input video file input.mp4 to the output file output.mp4, with a starting time of 10 seconds and a duration of 5 seconds. .
(3) Merge video files
You can use FFMPEG in PHP to merge multiple video files into one video file. The following is the sample code in PHP:
$videoFile1 = "input1.mp4"; //输入视频文件1 $videoFile2 = "input2.mp4"; //输入视频文件2 $outputFile = "output.mp4"; //输出视频文件 $cmd = "ffmpeg -i concat:"$videoFile1"|"videoFile2" -acodec copy -vcodec copy $outputFile"; exec($cmd);
The above code uses ffmpeg to merge the input video files input1.mp4 and input2.mp4 into the output video file output.mp4.
(4) Add watermark
You can add watermark to video files to protect their copyright. Here is the sample code in PHP:
$videoFile = "input.mp4"; //输入视频文件 $watermarkFile = "watermark.png"; //水印图像 $outputFile = "output.mp4"; //输出视频文件 $cmd = "ffmpeg -i $videoFile -i $watermarkFile -filter_complex 'overlay=W-w-10:H-h-10' $outputFile"; exec($cmd);
The above code adds a watermark image to the lower right corner of the input video file input.mp4 and saves it to the output file output.mp4.
- Conclusion
This article introduced some common ways to use PHP to process video files. Whether you want to compress video file size, crop video, merge video files or add watermarks, the FFMPEG library is a powerful and convenient tool. When implementing these operations, you should consider handling large video files to avoid memory issues and maintain optimal performance.
