This is a requirement for proper adaptive bitrate streaming in DASH and HLS. Keyframes aligned video files at different bitrates and resolutions.

In this section we will review how to produce MP4 files that work on devices where H.264 video and AAC-LC audio are supported. On-demand video transcoding to MP4 with AVC (H.264) video and AAC-LC audio - keyframes aligned renditions These tablesĭo not account for notions like 2-pass encoding or context-based encoding. These tables are to be considered as indication for you to find the best ladder for your streaming project. This guide will present encoding tables (a.k.a. Radiant Media Player does not provide licensing for encoding/decoding media content. Guidelines for compiling FFmpeg can be foundĮnabling some encoding/decoding options with FFmpeg can trigger licensing requirements depending on your use-case. Make sure you have the latest release version available for better results. General instruction for installing FFmpeg can be found here.

FFmpeg is a free and open-source software to transcode video and audio content. This guide also provides encoding tablesįor adaptive bitrate streaming for each codec. This guide describes how to create MP4 and WebM video files with various codecs with FFmpeg so they can be used with Radiant Media Player (and HTML5 video in general) for progressive download streaming.
