Welcome to Briefing. Yet another secure video chat.
Privacy is the driving force behind this project. It uses secure technologies like WebRTC to directly connect between participants. The website that provides the web app and mediates the communication stores as few data as possible and does not know anything about the contents of established conversations. No accounts are required. No cookies are used.
The difference between Briefing and most similar projects is, that it does not use a central server that distributes the video streams (SFU). The advantage of an SFU is that it saves bandwidth due to the fact that the own video does not being uploaded to each participant but only once. The SFU can also do more optimizations the clients might not support. But then the video signal is not end-to-end encrypted any more i.e. you have to trust the SFU provider. Briefing instead sends data from peer to peer directly ("Mesh") and therefore the data does not travel over the server under normal operation. The WebRTC peers however still trust the signaling server for the authenticity of the peer-to-peer communications encryption in place.
The default mental image of video compression involves unwanted video artifacts, like pixelation and blockiness in the image. This sells short, though, the complexity that actually goes into compressing video content. In particular, it overlooks a fascinating process called interframe, which involves keyframes and delta frames to intelligently compress content in a manner that is intended to go unnoticed.
This article describes this process in detail, while also giving best practices and ideal encoder settings that you can apply to your live streaming at IBM Cloud Video. Much of this specific advice relates to streaming due to adaptive bitrates.
Have you considered becoming a professional media server operator or user? Unsure of what technical skills you need? This is blog number three in our series on media server pros, and this time we’re digging further into the details of media server content (yes, video) for playback in media servers, based on recommendations from the fine people of the Media Server Professionals (Facebook) group.
Let’s pick up from where we finished in the last post!
Video bit depth or color depth
Understanding chroma subsampling
Video space and data rate calculations
Calculate chroma subsampling impact on file size
Drop frame vs non drop frame
Frame accuracy and keyframes
FFAStrans is an unattended Windows tool aimed at broadcasters and video professionals for automatic transcoding of media files through drop folders. It's based on FFMpeg and relies on AviSynth for filters. Also it's one of the few free tools which supports multiple watch folder with separate transcoding configurations. It's best compared with the likes of Telestreams Episode and Vantage, Harmonics ProCoder, Digital Rapids Transcode Manager, Adobe Media Encoder, Amberfin iCR etc. FFAStrans is targeted at those with lots of different media formats coming from lots of different places and wants the transcoding process done automatically.
V6 is a multimedia tool suite designed to augment audio / video workflows in a professional environment. Tools are designed for high fidelity color accurate video conversions, detailed Exif quality reports and easy-to-use audio and video measurement tools
The V6-Q can be used for loading in any number of media files for automated sequential playback – great for previewing a day’s video session or playing your favorite tunes! Multiple windows may be opened for running multiple sessions and functions as well
V6 is also designed to run on a wide variety of PC systems and will work even with modest resources – the more powerful the system the better the performance, but V6 will also run on lesser hardware so you can put that old PC back to work cranking out media conversions and Exif Reports!
