However this is where I face the probelms. I then use the DllImport('avcodec') to import the functions. Here are the steps I am using for this.ġ) Downloaded the latest version of ffmpegĢ) configured using -enable-shared and -enable-staticģ) copied all the dlls from ffmpeg to Assets/Plugins

This is useful for adhering to iOS Webkit's requirements for supporting the HTML5 video inline and autoplay attributes.I am trying to integrate ffmpeg into unity using the platform invoke on C#. This must go immediately before the output file name, e.g. If you wish to output a silent video, then you should pass the flag -an to transcode the video without an audio track. If you want to change the bitrate of the audio you can do so with the -ab flag, e.g. my-new-video.webm is the name of the output file.īy default, the audio track will be transcoded to the output file using the libvorbis encoder.Higher bitrates mean bigger files, which mean longer buffer times. You may want to tweak this value depending on the desired quality of the video. 1024k is the bitrate that the output video will have.libvpx-vp9 is the video codec library we will be using for the transcoding.webm is the container format we want to use for the output file (do not change this).You can use any type of video file (AVI, WMV, MP4, etc.) my-original-video.wmv is the filename of your source file.There’s a bit going on here, so let’s break it down while you wait for your video to transcode. Compiling ffmpeg with every available codec takes a long time, so we’ll just build with the three codecs we need:įfmpeg -i my-original-video.wmv -f webm -vcodec libvpx-vp9 -vb 1024k my-new-video.webm On OSX, use homebrew to build ffmpeg on your machine. Here’s a step by step guide to getting the files you need for any browser to natively play your video. With that said, it does require you have at least a basic knowledge of multimedia encoding, so it can be a little daunting if you’re just looking to create the necessary files to use the tag on your site.

It supports just about every codec going and has a relatively simple interface. The WebM filesize is 40% that of the MP4.įfmpeg is a hugely powerful tool. The same file transcoded to H.264-MP4 and VP9-WebM with the same bitrate. Using ffmpeg you can transcode any multimedia file into WebM and MP4 from your command line. Currently all major browsers support MP4, but WebM allows for a much better quality-to-filesize ratio. There are only two file types required to natively play video in any modern browser with HTML5: WebM and MP4.
