![]() Also, in our examples, there won’t be anything too fancy going on. It also implements many useful features, such as tracking the progress of a command and error handling.Īlthough the commands can get pretty complicated quickly, there’s very good documentation available for the tool. The library, available on npm, generates the FFmpeg commands for us and executes them. under a wide variety of build environments, machine architectures, and configurations.īoasting such an impressive resume, FFmpeg is the perfect choice for video manipulation done from inside of the program, able to run in many different environments.įFmpeg is accessible through CLI, but the framework can be easily controlled through the node-fluent-ffmpeg library. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. ![]() ![]() In the documentation, we read:įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Manipulating a video with Node.js itself would be extremely hard, so instead we are going to use the most popular video manipulation tool: FFmpeg. We are going to take a closer look at how to implement both of these approaches. Another popular way of creating a preview is to take a few frames from a video and make a slideshow. YouTube, for instance, plays a 3- to 4-second excerpt from a video whenever users hover over its thumbnail. Generating video previews with Node.js and FFmpegĮvery website that deals with video streaming in any way has a way of showing a short preview of a video without actually playing it. Here's a picture of a corrupt video and a working video.Maciej Cieślar Follow A JavaScript developer and a blogger at. This works fine for 50% of the videos I've tried, but doesn't for other videos. Res.status(500).send("Internal Server Error") Ĭonsole.error("An error occurred while taking the screenshot:", err) Ĭonsole.error("An error occurred while downloading the video:", err) Īwait unlink(videoPath) // delete the file on errorĬode Summary: Basically I'm passing the videoID and timestamp (because I want to download a certain section of the video, not the whole video), it downloads the video, then takes a screenshot of the video at a certain timestamp (i.e 1st second) and sends the screenshot to Cloudinary (a cloud file storage). "An error occurred while uploading the screenshot to Cloudinary:", Here's my code (read TL DR below): router.post("/screenshot", async (req, res) => `) This is the error I get when I try to take screenshot of the corrupted video:Įrror: ffmpeg exited with code 1: Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_split_0Īnd obviously, error is there because the video is corrupted, but WHY is that the case? But the issue I'm facing is - some videos are downloaded and are completely playable, but others are corrupt. So I'm using ytdl-core & ffmpeg to convert some videos from YouTube to MP4 and then manipulate them in a way or take screenshots. ![]()
