As much as we love FFmpeg for transcoding op?erations, it can get frustrating when packag?ing your content for ABR delivery. By packag?ing, I mean formatting and segmenting your media files, creating manifest files for HLS and DASH, for?matting for CMAF, and managing multiple audio and subtitle streams. Fortunately, there are easier-to-use solutions that are equally open source and equal?ly free. In this article, I'll focus on GPAC, which is a great packaging alternative.
