Media Streaming Libraries for Xamarin


Intoduction

Xamarin provides a unique possibility to re-use the same codebase for multiple platforms simultaneously. VASTreaming offers the streaming library for all platforms supported by Xamarin. Library can be used for platform specific project as well as in Xamarin.Forms in completely abstract fashion, hiding any device specific implementation.

RTMP

RTMP is an old protocol, owned by Adobe and tightly bound to Flash technology from the very beginning of its existence. Even though Flash has been deprecated after dominating over the content rich web for many years, RTMP is still alive. It is due to the fact that RTMP supports so-called publishing when a live media stream is pushed by a client to a server for further distribution. Many modern protocols lack this publishing feature.

Starting from the Flash days, existing server infrastructure still uses RTMP and will be using it for a long time. YouTube, Facebook, Twitch - you name it, all of them use RTMP ingestion for live streams. If a future app is expected to provide their user with a feature of publishing video streams in social networks, it should use RTMP. Therefore, investing into a RTMP library is not a waste of money but quite the opposite. In fact, it guarantees the compatibility with most popular content distribution networks.

VASTreaming RTMP library for Xamarin provides the ability to publish a live stream to RTMP server, pull and watch a stream from RTMP server as well as run a tiny RTMP server with the ability to ingest published streams and re-distribute streams to connected clients. See RTMP library page for more details about the protocol itself as well as our implementation details and specifics.

RTSP and RTP

RTP and RTSP are among the oldest streaming protocols. But they are still actively used because of such protocol features as low latency (in regard of RTP) and support of so-called publishing (in regard of RTSP) when a live media stream is pushed by a client to a server for further distribution. Many modern protocols lack this publishing feature, because already created ones work well enough covering all needs for video streaming software development.

RTSP found wide adoption in security while RTP is actively used in VoIP. Even the relatively fresh WebRTC utilizes RTP as a media transport. So, there is no lack of applications for both RTSP and RTP protocols. Their wide popularity guarantees wide compatibility for new software products using them.

VASTreaming RTSP library for Xamarin provides the ability to publish a live stream to RTSP server, pull and watch a stream from RTSP server as well as run a tiny RTSP server with the ability to ingest published streams and re-distribute streams to connected clients. See RTSP library page for more details about the protocol itself as well as our implementation details and specifics.

Capture and Encoding

VASTreaming streaming library for Xamarin, in addition to streaming itself, provides built-in functionality to capture and encode from almost any client device. Camera, microphone, screen capture, or any other media can be used as a source for live streaming. Moreover, on certain platforms, it is possible to mix the following video sources together in real-time:

Multiples approaches are available for fast image processing, for example render scripts and OpenGL. The fastest or most suitable method can be chosen based on the customer preference or platform specifics.

Transport Stream

Transport stream (TS) is a media format most suitable for streaming or media transmission systems. HLS as well as other protocols, most notably MPEG-DASH utilizes TS for media data segments. In addition to that TS itself can be used for direct streaming via multicast or even via pushing it by HTTP server (so-called TS over HTTP).

VASTreaming TS library for Xamarin allows to decode transport stream received by any means, for example as a file or RTP payload. See HLS library page for more details about the protocol itself as well as our implementation details and specifics.

MP4

VASTreaming MP4 library for Xamarin is a flexible and highly configurable library to read and write MP4 files and MP4 fragments. It’s suitable for customers not satisfied with the functionality of the standard MP4 reader/writer on Windows, Android or iOS.

Among the advanced features of the VASTreaming MP4 library for Xamarin are:



Implementation

VASTreaming streaming library for Xamarin is written in C# for maximum compatibility and easiest integration into existing Visual Studio solutions.

For customer needs, any custom streaming features could be easily implemented with this library, including streaming protocol extensions.
