How to concatenate two mp4 videos with the help of

问题:

Could anybody help me with the php code for FFMPEG to concatenate two mp4 videos and store the concatenated files as an mp4 at any folder in the server?

回答1:

For the FFMPEG part see here: Concatenate two mp4 files using ffmpeg

For the PHP part, you can invoke any command using: http://php.net/function.exec

I not succeed with mp4 videos, but i succeed using two webm videos. I worked with Windows 8.1.

What I did? Steps:

1. Install local webserver, such as, XAMPP or EasyPHP: I used EasyPHP DevServer 14.1 VC11. Available: http://www.easyphp.org/easyphp-devserver.php

2. Go to folder "path\EasyPHP-DevServer-14.1VC11\data\localweb" and create new folder, e.g. FFMPEG_PHP

3. Download FFMPEG for Windows: download 32-bit Downloads or 64-bit Downloads version Static. I used "Download FFMPEG git-013498b" 32-bit Static. Available: http://ffmpeg.zeranoe.com/builds/

4. Copy file "ffmpeg.exe" to folder "FFMPEG_PHP"

5. Store 2 or more webm videos in folder "FFMPEG_PHP". I download videos from youtube. See 1:48 minute this video how download videos from youtube:

6. Create "joinVideos.php" in "FFMPEG_PHP"

See code I did in "join Videos.php" below:

     <?php
        $joinVideosTXT="joinVideos.txt";			
		$joinVideos=fopen($joinVideosTXT,"w+");

		
		


		//Writes "joinVideos.txt"
		$video="nameVideo1";
		$video2="nameVideo2"; 	
		$pathVideo=$video.".webm";			
		$pathVideo2=$video2.".webm";
		$strVideo="file '".$pathVideo."'"."\r\n";			
		$strVideo2="file '".$pathVideo2."'"."\r\n";
		
		fwrite($joinVideos, $strVideo);
		fwrite($joinVideos, $strVideo2);							
		fclose($joinVideos);

		
		
		$ffmpeg="ffmpeg.exe";
		$videoFinal="videoFinal.webm";
		
		unlink($videoFinal);//remove previous $videoFinal         
		$cmd="$ffmpeg -f concat -i " .$joinVideosTXT." -c copy ".$videoFinal;
		
		
		system($cmd);
		
	?>
	

	<video controls="controls">
		<source src="videoFinal.webm" type="video/webm">
	</video>
</body>
  

 

IMPORTANT: when you run first time "joinVideos.php", you MUST comment line "unlink($videoFinal);//remove previous $videoFinal".
