Nobody want to store large video / audio files into their server hard disk or s3 buckets. So while uploading, they are all expecting to compress the video or audio files without losing originality, when we upload a video or an audio files in to their application. We do have functions & tag to manipulate image files in ColdFusion, but We don't have any ColdFusion build in option (tag / function) to manipulate audio / video files. You might heard of ffmpeg and it's wide usability. it is mostly in videos & audios sites such as YouTube/soundcloud or any other similar site. ffmpeg is very simple to learn. On ColdFusion, we can able to compress the video or audio files using
FFmpeg utility. it is a free open source command line utility compatiable with all major operating systems (Windowns, Linunx & Mac). As We are going to demonstrate this process in Windows operating system, so we will be using FFmpeg
.exe files. ColdFusion has the facility to run the executable (
.exe, .bin, .bat, .sh ) files using
cfexecute tag. Other than, video compression, ffmpeg can be used to know the duration of the movie/audio in seconds to retrieving the bitrate of the movie/audio file. This can be very helpful when you are developing application that has to do with uploading videos because you can know a lot of information about it.
If your blog / web site is missing out a customized forms (contact us, restaurant booking forms, car rental forms, newsletters subscribing forms..etc ), then you are missing out lot of opportunities every day. Just adding contact mail ID in your website will not solve this problem & but it will add more problem like getting spam mails from email harvesters. Form builder is an essential feature of a Content management system or blogging engine. But few of very famous open source projects such as wordpress don't have a form builder feature built-in. But PresideCMS provides an awesome drag and drop feature rich form builder module, that enables content administrators to build input forms to gather submissions from their site users.
