The following article covers the process of making a GIF from a video using FFmpeg: How to Make a GIF from a Video using FFmpeg. The following command can be used to extract audio from a video: $ ffmpeg -i input.mp4 output.mp3 Converting a video to GIF For example, here's how to convert a video to MPEG-4: $ ffmpeg -i input.mp4 -c:v mpeg4 output.mp4 Converting a video to MP3 Simply pass the codec to FFmpeg with the -c:v argument to convert it to one of the formats. Simply use the following command to convert any video to VP9: $ ffmpeg -i input.mp4 -c:v libvpx-vp9 output.webm Supported video formats by FFmpegįor a list of all the video formats that FFmpeg supports, use the following command: $ ffmpeg -codecs Support for VP9 has greatly increased in recent years, making it a solid choice for online video.

Webm to MP4 converter using ffmpeg and Nodejs. Alternatively, if you also want to convert the audio track to a modern audio format such as AAC, use -c:a aac. Clone this repository and do a npm install. When we use -c:a copy, no re-encoding is done on the audio track.When the -pix_fmt yuv420p argument is specified, 4:2:0 subsampling is used, a widely used and supported pixel format.The -c:v libx264 argument tells FFmpeg to use H.264 video compression.Converting a webm file with various audio and video codecs to an MP4 file with H.264 video and AAC audio. When the WebM file contains VP8 or VP9 video, you have no choice but to transcode both the video and audio.
$ ffmpeg -i input.mp4 -c:v libx264 -pix_fmt yuv420p -c:a copy output.mp4 The simplest catch all command to convert WebM to MP4 using FFmpeg is: ffmpeg -i video.webm video.mp4. Here's how to convert any video to H.264, a format that's mostly associated with MP4. For this tutorial we'll use FFmpeg 5.1.2, but any recent version will do. It's also a very robust solution for implementing video automation, as we use it extensively in our own video editing API. Then saves audios from the original videos into the 4 different formats and saves the generated collage video into the separate file.Īs you can see, you can take multiple input sources, perform the complicated processing for them and produce multiple output files in the same time, in the one ffmpeg command.FFmpeg is a free and open-source video editing tool capable of trimming, cropping, concatenating, muxing, and transcoding almost any type of media file you throw at it. This code takes 4 input videos, then the negates the first video, stores result in stream, detects edges in the second video, stores result in stream, horizontally flips the third video, stores result in stream, vertically flips the fourth video, stores result in stream, then takes this 4 generated streams ans combine them in one 2x2 collage video. Alternatively, if you want to convert MP4 to WebM, you will need to type in the codec library explicitly (-c:v libvpx for video encoding, and -c:a libvorbis for audio encoding). > map( array( '3:a'), new Aac(), 'video_4.aac') FFmpeg supports decoding VP8, VP9 video codec and Opus, Vobis audio codec natively, meaning you can convert WebM to MP4 without specifying the codec library to use. $advancedMedia = $ffmpeg-> openAdvanced( $inputs)
