Authors Daniel SilhavyDuring the WWDC 2021 conference, Apple announced a new tool called Advanced Video Quality Tool (AVQT): “AVQT is a macOS command line tool, which estimates perceptual quality of compressed videos, that might contain video coding and scaling artifacts”. [1] Similarly…
Authors Daniel SilhavyTo some degree, we can compare a DASH MPD to a novel. A novel usually has multiple chapters (DASH periods) with exciting parts (high quality segments) and rather boring parts (low quality segments). Sometimes, we even skip some chapters (seek)….
Authors Daniel Silhavy and Stefan PhamAs head developers of the dash.js project we are frequently facing situations in which we have to evaluate if the failure of a DASH stream is caused by an actual bug in the implementation of the dash.js player or by…

Authors Daniel SilhavyIn times of Corona not only are big conventions shifting to online meetings but Fraunhofer FOKUS (and many other companies,) have transitioned their regular town hall meetings to virtual settings as well. In this blog post we will explain how…
Authors Daniel SilhavyHTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (MPEG-DASH) are the two main formats used for adaptive streaming. While HLS is natively supported on most of its target platforms (iOS and MacOSX), external players are needed for MPEG-DASH….
