If you have a bunch of videos and you want want merge all of them to create one big video, you can easily do it here. You can easily convert one video format into another: $ ffmpeg -i inputVideo.h264 -c:v libx264 outputVideo.mp4 ![]() The above command will create two output videos where the first one will be from start to 35 seconds and the second one will be from 35 seconds till the end. You can split the video into multiple parts as well: $ ffmpeg -i inputVideo.mp4 -t 00:00:35 -c copy subVideo1.mp4 -ss 00:00:35 -codec copy subVideo2.mp4 The “-t” parameter specifies the duration of the video clip in seconds. Here, “-ss” is the time offset parameter to specify the starting timestamp in the format “HH:MM:SS.ms”. Let’s say you want to extract a 23 second video starting at timestamp 1 min 45 seconds: $ ffmpeg -i inputVideo.mp4 -ss 00:01:45.0 -codec copy -t 23 outputVideo.mp4 You can do pretty much everything with videos you can possibly think of! Let’s explore it on a case by case basis. Now that we have installed FFmpeg, it’s time to play around with it. NODE FFMPEG TRIM VIDEO INSTALLInstall it using the following command: $ brew install ffmpeg -with-fdk-aac -with-ffplay -with-freetype -with-frei0r -with-libass -with-libvo-aacenc -with-libvorbis -with-libvpx -with-opencore-amr -with-openjpeg -with-opus -with-rtmpdump -with-schroedinger -with-speex -with-theora -with-tools This command will check whether or not the installation was successful, along with checking if you can install formulas (Homebrew Packages). Verify the installation using the following command: $ brew doctor Run the following command from your terminal: $ ruby -e "$(curl -fsSL )" Now install the command line tools using the following command: $ xcode-select -install If not, install Xcode from the app store (it’s free). This is, of course, assuming that you have Xcode installed. To install Homebrew, you need Xcode command line tools. If you have Homebrew already installed, you can skip to the next section. ![]() Let’s go ahead and install it using Homebrew. NODE FFMPEG TRIM VIDEO HOW TOLet’s go ahead and see how to manipulate a video using this amazing tool, shall we?įFmpeg is a command line tool that’s really powerful and very easy to use. FFmpeg is here for you and you can do a lot of things with it. NODE FFMPEG TRIM VIDEO SOFTWAREThe good news is that you don’t need some fancy commercial software to edit videos. Can you do it quickly? Well, not unless you know how to use some bloated software whose GUI usually has a steep learning curve! A lot of people tend to get stuck when they want to play around with videos. Let’s say you want to resize a video, extract a 10 second segment from it, and then convert it to a different format. You can quickly crop, resize, or manipulate an image without skipping a beat, but you can’t do the same for videos. We know that there are a lot of tools available for image editing. I made myself sure that all the variables have the right values so the error doesn't come from there.Editing videos can be a huge pain if you don’t have the right tools. This.resizeVideo = function(capturePath, index, beginTime, endTime) ).save(pathFolder + 'test.' + pathFolder) ![]()
