This is a Premium feature.
Thumbnail Images help to identify the respective videos in a gallery without playing them.
When you add videos from third-party video services like YouTube, Vimeo, and Dailymotion, our plugin will use their respective API, grab the image URL from their server and add them to your video automatically.
But, this is not possible with the self-hosted videos and we receive a lot of emails regularly asking a solution for this issue. We are glad that from version 1.6.6 (Premium), “All-in-One Video Gallery” can generate thumbnails from your self hosted MP4 videos too.
This can be done in 2 ways,
1. Automatically using FFMPEG
Your server should have FFMPEG installed to get this work. Follow the steps below to enable this feature,
1. Go to Video Gallery / Settings / Advanced from your WordPress Admin Panel
2. Select the “Auto Thumbnail Generator” submenu
3. Configure your “FFMPEG Path” and the “Number of Images” to auto-generate.
Kindly use the “Test FFMPEG” button to make sure the FFMPEG path you configured is valid.
Now, when you add a video by selecting the “Self Hosted / External URL” source type using the video form back-end, the plugin will auto-generate thumbnails from your video file and add them under the “Image” field as in the screenshot below. You simply can select the image that best suits your video and save the form to get it added.
2. By playing the video file and capturing a scene using the “Capture Image” option
Enable the “Capture Image” button from the “Auto Thumbnail Generator” settings page to activate this feature.
When you enable this option, you will get a button named “Capture Image” in the video form under the “Image” field. Clicking on this button will open a popup as in the screenshot below using which you can play the video file in the form and capture the screen you wish as a thumbnail image.
