Search “upload_max_filesize=128M” in your php.ini file and change it’s value to 512M or 1GB or any other size you want. You may need to change some of the settings to allow the user to upload larger files. If you are using Windows OS, then it will be in your XAMPP “php” folder. Mostly it is located in your XAMPP “etc” folder if you are using Linux or Mac, or if your site is live on server. When uploading large files, php.ini plays an important role either you are working on localhost or on live server.
The videos of larger length and of high quality will take longer to process than the one in shorter length. The time required to process the video and generate thumbnails depends on the length and quality of video. After selecting the video file when you hit the submit button, you will see several new image files will be created at the root of your project’s folder with a prefix thumbnail-“. Now you can run the script and you will see a form with an input field from where you will be able to select the video from your computer.
We are creating a form that will allow you to select video whose thumbnail needs to be generated. You can download it from it’s official site. In order to generate thumbnails from video, you must have FFmpeg installed in your system. In this tutorial, we will be creating a similar script that will generate thumbnails from video and save them as separate files. Similarly Facebook generates 10 images when you upload the video. When you upload any video on YouTube, by default it generates 3 images from the video. You can tell to capture image every 60 seconds, for example. But if you wanted to generate multiple images of video, like YouTube and Facebook does, you need to tell the frame interval. For example, you need to tell the time in this format (hh:mm:ss). If you wanted to get just 1 image from video (also known as screen capture) you need to tell the time duration from where to capture the screen. You can generate a list of thumbnails from any video or you can create just one. The first frame will be seen as a static image. The video which has a GIF thumbnail allows you to hover your mouse over the video to play the GIF. You can show single image as a thumbnail, or you can show a GIF image which is a series of multiple frames. Thumbnail is just a preview of a video so user can see what’s inside the video before playing it. And our script will generate thumbnails of that video after regular intervals. In this tutorial, we will be creating a script in PHP and FFmpeg.
