"dash" parameter ensures that DASH compliant WebM files are created. The "keyint_min" and "g" parameters make sure that all the video streams have aligned Cue Points. We create 5 video streams and 1 audio stream each with varying resolutions and bit rates. įor the sake of examples, let’s assume there is a raw video source named “input_video.y4m” and a raw audio source named “input_audio.wav”. For more information on what this means see this link. Step 1: Create the Video and Audio Streamsįor streaming WebM files using DASH, the video and audio files have to be non-muxed and non-chunked (i.e.) each video stream goes into it’s own file and each audio stream goes into it’s own file. You can either download nightly static build from or build FFmpeg yourself from the git repository.
Note about FFmpeg: You will need to download the latest (tip-of-the-tree) version of FFmpeg in order for some DASH features to work. If you are looking for the old (and obsolete) page that used FFmpeg, libwebm and webm-tools, it has been moved here: This page describes the recommended ways to create, stream and playback WebM files using DASH.
