HDS VS HLS – Which is better?

Thanks for checking us back again! As a short recap on our Streaming Mini-Series so far, we’ve started by analyzing the overall difference between Streaming Technologies and Progressive Downloads (something we still owe a proper introduction to, and we’ll cover as we move forward), and then started our journey through Streaming Proprietary Technologies. Adobe was the first proprietary brand we’ve been introducing through our past three articles on RTMP, HLS and HDS, and today’s article completes our introduction to Apple/Adobe by questioning something rhetorical – “which is better, HDS or HLS?”. Before getting technical with the article, let us kindly remind you we’re barely halfway through our Streaming Mini-Series journey: we have yet several Streaming and so-called “Pseudostreaming” technologies or “methodologies” to cover, not to even mention security considerations which are an additional layer of complexity when it comes to Securing assets. Let us now start specula...

Streaming Media Delivery Using NGINX Plus

NGINX is widely used to deliver MP4 and FLV video content using progressive downloads or HTTP pseudo-streaming . Progressive downloads rely on the efficiency of the streaming server to handle disk I/O and concurrent connections, while MP4 or FLV pseudo-streaming capabilities also allow the clients to use a simple “trick-play” technique to seek to the desired position in a video stream without needing to download the entire resource. NGINX Plus extends this capability to support adaptive streaming for video-on-demand (VOD) applications with Apple HLS and Adobe HDS , and Flash-based services using RTMP . Among other benefits, adaptive streaming allows the video player to select the most appropriate bit-rate in real-time. NGINX Plus can also impose smart bandwidth limits on individual MP4 streams to prevent fast clients and download accelerators from using unnecessary resources, and the enhanced session logging capabilities of NGINX Plus reduce the overhead of the stan...

The Best Encoding Settings For Your 4k 360 3D VR Videos FREE Encoding Tool

One of the most time consuming and frustrating tasks we encountered during our first 360 3D video productions was finding the optimal encoding settings for each of the currently available VR headsets. Each platform supports different resolutions, frame rates, codecs, and bitrates. This article explains the settings we started with, what we learned from analyzing some of the legends in the field (like Chris Milk and Felix & Paul), and finally we’ll share a simple yet powerful free tool we built to help you encode your VR video content with the best possible settings. Let’s go! Our ignorant phase We at Purple Pill VR film in stereoscopic 3D on all sides, which ultimately results in one video file containing 2 panoramas, one for your left eye and one for your right eye, stacked on top of each other. This file, a .mov or .avi, has an exotic 1:1 aspect ratio and a resolution of 4096×4096 pixels at 60 frames per second. Not a single VR headset is currently able to p...
