DaCast is a simple yet flexible solution for how to stream live video on a website. The live stream hosting platform is designed with a streaming as a service approach. DaCast gives professional tools and utilities all featured through cloud computing and from a content delivery network in order to reach worldwide audiences.
Live video retransmission on the internet, often called live video streaming, is a several step process.
First, a source is needed, which can be either digital such as webcams or analog, which requires digitizing through a capture card before it can be streamed.
The second step is encoding through DaCast. The service supports all encoders that can output in RTMP live streaming (Flash). This includes broadcasting video software encoders such as Wirecast, Discover Video and also Adobe Flash Media Live Encoder, which is a free download. Professional hardware encoders can also be used, such as the Niagara line, TriCaster, VBrick and TouchStream.
In the third step, the stream is sent through a secure internet transmission to our servers. Through a partnership with EdgeCast, one of the leading worldwide content delivery networks (CDN), media is then distributed worldwide to any viewer with an internet connected device.
Depending on setup, this can be a quick and easy process. For a step by step guide on video hosting and how to live stream video for web application, please consult our streaming walkthrough.
Once broadcasting live video, also known as a live streaming webcast, the content can be published on websites. This is achieved through using a code for embedded videos, or through a complimentary and optional DaCast channel page.
Streams may also be used over social networks including Facebook, where a URL-like code is given that broadcasters can attach to walls without the need for viewers to download plug-ins. These streams can then be watched directly from a Facebook wall while viewers can comment, share and like the content.
When DaCast is being used to stream video to a website, this content can then be accessed from computers, mobile devices such as Android phones, internet connected televisions and video game systems.
The DaCast streaming platform allows video streams to be sent in different formats, specifically VP6 and H.264. Supported audio track formats include MP3, AAC and M4A. The system supports bitrates of up to 5 Mbs.
When broadcast through the DaCast streaming live service, these video and audio codecs will be encapsulated and streamed from a free Flash Video Streaming player. Stream quality is determinable by the broadcaster, going from very low quality all the way up to true high definition.
There is a great deal of importance in understanding how a viewer will interact with a feed when deciding upon its creation. This is especially true for live web streaming services, where data is sent without the ability to pause and buffer, a method of storing video server side for playback.
There are two determinates for live stream quality beyond selecting a bitrate and establishing encoding preferences. This is connection speed from the broadcaster and the viewer. For example, if one has an upload speed of 750 kb a second, they will be limited to a maximum of around 700 kb a second for video streaming.
For viewer connection speeds, the DaCast platform presents a solution for high definition streaming. By presenting an option for multi-bitrate, broadcasters can stream in great quality but also define lower quality versions that will then be selected, automatically or manually, by viewers on slower connections such as mobile devices.
When using the DaCast stream video server, the user will have full access to a rich array or monetization features offered in the cloud to start profiting off their live streaming.
Optional ads can be attached to channels to start generating money right away, and are selectable from a variety of options. These are pre-negotiated without the need for additional signup.
Pay per view and subscription services are also available and featured inside the media player with DaCast's Pay-in-Play interface for a high conversion rate. DaCast lets the broadcaster focus on content while generating revenue at the same time and offers a full payment system included.
