I’m am building a website where you can upload a video or an audio file. I have a limit of only 15 seconds, but I would like the user to be able to select which 15 seconds of the video or audio file after uploading with an input type=“file”. Is there a special way to do this with javascript or is there any plugins that could do this for me?
You can do it with the EXEC command
