You will need to type commands with your keyboard to transcode multimedia files and streams. It packs many encoders and decoders, making it powerful enough to support almost all common and uncommon multimedia formats.įFmpeg comes with a learning curve especially if you are new to a command line tool. You can use only -map options.FFmpeg is a free and open-source command line-based tool to handle video, audio, and other multimedia files. 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. 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. $advancedMedia = $ffmpeg-> openAdvanced( $inputs) To concatenate videos encoded with the same codec, do as follow: In both cases, you will have to provide an array of files. Your files MUST have video and audio streams. You also need to pay attention to the fact that, when using the saveFromDifferentCodecs method,
With the second function, you will be able to choose which codec you want for the generated file. The first function will use the initial codec as the one for the generated file.
If your sources have been encoded with different codecs, you will want to use the FFMpeg\Media\Concatenate::saveFromDifferentCodecs. If your sources have all been encoded with the same codec, you will want to use the FFMpeg\Media\Concatenate::saveFromSameCodecs which has way better performances. There are two ways to concatenate videos, depending on the codecs of the sources.
This feature allows you to generate one audio or video file, based on multiple sources. If you don't set it, you will get a fixed gif image. This method has a third optional boolean parameter, which is the duration of the animation. > gif( FFMpeg\ Coordinate\ TimeCode:: fromSeconds( 2), new FFMpeg\ Coordinate\ Dimension( 640, 480), 3) $video = $ffmpeg-> open( '/path/to/video' )
