Adobe Connect is a proprietary platform for virtual presentations, conferencing sessions and screen recordings. Recently, one of our customers has requested our assistance in migrating their content from Adobe Connect to Kaltura. We've released the project as FOSS [licensed under AGPLv3]. This session will cover the challenges we faced and the FOSS tools we used to overcome them.

During the session, we will review the steps the code takes in order to extract and process the data associated with an Adobe Connect recording [video and audio files, metadata, etc]. We'll walk attendees through our use of FFmpeg, Selenium, Mozilla's Geckodriver and OpenCV and demonstrate how they were harnessed for the purpose of migrating the content.

We will conclude with a live demo of the migration process.

FFmpeg is a FOSS, cross-platform, solution to record, convert and stream audio and video. This session will focus on using the CLI tools included in this project [ffmpeg and ffmprobe] to accomplish everyday video manipulation and streaming tasks.

The session will include a live demo showing how to achieve the following goals:

• Extract metadata from video and audio files
• Convert between different media types
• Live Stream over RTMP
• Record screen display
• Basic editing operations [concatenation of several video files into one, extracting the audio track from a video, etc]

The <video> element was first proposed by Opera Software in February 2007. Opera also released a preview build that was showcased the same day and a manifesto that called for video to become a first-class citizen of the web.

Integrating video elements into the HTML5 standard has changed the world forever and for the better and enabled us to gradually rid ourselves from the proprietary, exploitable and often slow FLASH technology. However, the means to embed video in HTML5 enabled web pages is only the tip of the iceberg. In this session, we will discuss other crucial aspects of handling and serving video.

This session will cover in detail the following aspects and how we handle them in the Kaltura Open Source Video Platform:

• Video ingestion [uploading, encoding/transcoding]
• Content distribution and Caching
• Redundancy
• Metadata cataloging and Searching
• On-the-fly repackaging of MP4 files into DASH, HDS and HLS

We will conclude with an end-to-end demo of the Kaltura Video Platform.

The session will walk attendees through configuring Nginx with the RTMP module and the Kaltura HTML5 player to achieve a fully functional, end to end, FOSS, live streaming solution.

During the session, we will review the various components needed for the solution and conclude with a demo consisting of streaming to Nginx over RTMP using FFmpeg and playing the stream using the Kaltura HTML5 player.

Kaltura makes use of Mediainfo to detect source video attributes and FFMPEG in order to optimise the transcoding of source videos into multiple flavours to be consumed by different devices.

The session will review how this is achieved using the KDL [Kaltura Decision Layer].

The session will cover the following sub-topics:

• Video file detection and transcoding

  • Transcoding Profiles and Flavor Params
  • Mediainfo
  • FFmpeg
  • A walk through the KDL [Kaltura Decision Layer] code

• Playback

  • Playback methods [Progressive HTTP, HDS, HLS, DASH]
  • What is a playback manifest?
  • An end to end walk through of the playback process

• Live demo

Kaltura is widely used to address a wide range of education, media, and enterprise video needs. In this talk covers how Kaltura interact with open source components for an end to end scalable FOSS video platform. We also cover how the core open source Kaltura platform interacts with these components, giving best practices for your own online video projects weather using a single component or integrating with a larger platform.

In addition to contributing its core server as an open source video platform offering, Kaltura makes use of many third party FOSS projects. This session will walk attendees through major projects used by the Kaltura platform to ingest, analyze, optimize, record and play video files, and provide guidance in optimizing use

The following projects and their role in our architecture will be surveyed:

• Kaltura server -- Pulls together all the media services under a unified REST API.
• nginx-vod-module - An Kaltura developed Nginx module for On-the-fly repackaging of MP4 files to DASH, HDS, HLS, MSS
• Mediainfo - used to analyze source videos to determine how best to handle them
• FFMPEG and Mencoder - used in transcoding to optimize source videos so that they'll be best viewed by various devices; i.e: Desktops, tablets and cellphones running different OSes
• ImageMagic - used for image manipulation and thumbnail creation
• Red5 - used in order to record from webcams, and broadcast live streams.
• The Kaltura HTML5 player - used for playback in native and web environments.

The session will include a review of our video source detection and optimization processes as well as demos showing how each project is used within the platform.

We will conclude with an overview of our current community activities and focus.
