Why We Require Video Delivery Format For Web 2

Video has come a long way since magnetic tapes were involved and it’s time to ensure that you’re using the best format for displaying video content on your website. Including videos helps make your content easier to connect with the people. If you’d like to have greater control over your video then the HTML5 video is your solution. the HTML5 only works with a few file formats (currently) – MP4, OGV, WebM, and WebVTT – and each format has at least one strong reason to employ it.

One of the biggest sources of confusion about the video is not realizing that the file format is completely different from the video format. So we are always dealing with two formats, not one. Sometimes files formats are called container formats because they are the containers for the actual video. In fact, the video format is the flavor of compression that is used in the video.

# MP4 It is the most widely used media format for the digital devices and many platforms support MP4 which makes it universal video format around the world. The MP4 can also store video files, audio files, text, and still images and they can retain high video quality while maintaining relatively small file sizes.

# OGVOGG was originally designed as an audio compression package in the early ‘90s but matured over the next two decades. What started as a workaround led OGG to give birth to OGV, a digital multimedia file format redesigned for efficient streaming over the internet. The format does not (currently) work with any version of Internet Explorer nor Safari.

# WebM – Introduced in 2010, WebM is a completely open-source video format which delivers the highest quality video in real-time, adjusting file weight depending on connection and processing power. It is designed and developed with widespread web use and sharing in mind and has its compatibility with Chrome on Android devices.

# WebVTT – WebVTT was developed by W3C (the World Wide Web Consortium) in 2010. It is the most compatible video tag format currently available. The cross-operating system and cross-browser support WebVTT and make it the logical choice for videos on any website. 

How Progressive Download Works?

Progressive download is a method which is used to stream media from the web server to the client such as a video player on a laptop or mobile phone. Without using progressive download a client has to download the entire media file before video playback can start. Media files are typically large, so users must wait a significant time before they can watch the video, resulting in disappointing user experience. With progressive download, only a small part of the video file has to be downloaded before playback begins. The progressive download is video delivered by a regular HTTP web server rather than a streaming server. In most instances, the video delivered using this technique is stored on the viewer’s hard drive as it is received and then it is played from the hard drive. 

How RTMP STREAMING Works?

Real-Time Messaging Protocol was basically a protocol developed by Macromedia (owned by Adobe). It gained its popularity for streaming audio, video and data over the Internet between a flash player and a server. There is a direct pointer from the media server to flash player, and only data corresponding to that pointer is held by the flash player. A video player is used for sending the streams file corresponding to its screen size and internet connection speed. In RTMP streaming process it is ensured that if a viewer is initially viewing a high-quality stream at high bandwidth and after some time if the internet speed drops then the video player will immediately switch to a lower resolution stream. In this process, there is no storage of any kind of data on the computer. 

How HTTP STREAMING Works?

HTTP live streaming is the streaming which can host the streamable content without a streaming server because of the HTML5 and hypertext transfer protocol. HTTP Streaming is a push style type data transfer method that allows a web server to continuously the send data to a client over a single HTTP connection that remains open indefinitely. With HTTP Streaming, the server is configured to hold on to a specific request from a client and keeps the response open so that it can pass data through it. When updates pertaining to the request are available along server-side, the server sends the response through the request-response channel and only closes the connection when explicitly told to do so.
