With so many ways to watch videos today from catching up on TV shows to experiencing live sports two options stand out: Video on demand (VOD) and Live streaming.
Did you know that over 80% of viewers prefer video on demand for its convenience, while nearly 70% tune in to live streaming for real-time excitement. In this blog we will discover how these popular options stack up in today’s streaming landscape.
What is VOD streaming?
Video on demand is access video content at any time, rather than being tied to a specific broadcast schedule. Video on demand (VOD) offers flexibility, allowing users to watch pre-recorded content at their convenience.
It is like having a huge library of movies and shows right at your fingertips. VOD is a way to stream your favourite shows and movies whenever it suits you, just like flipping through channels on a TV, but with a much bigger choice and control over what you see.
- Watch whenever you want: Pick any show or movie from the library and start watching whenever it fits your schedule. For example Netflix, Prime, YouTube etc.
- Pause and rewind:Need a break or missed a part? No problem. You can pause, rewind, or fast-forward as you like.
- Choose what to watch: Browse through categories, see recommendations, and choose exactly what you want to watch.
Video on demand (VOD) offers flexibility, allowing users to watch pre-recorded content at their own convenience.
For users
Entertainment purpose they watch movies, shows and videos for fun. For educational content they learn new things with videos on different subjects. Also useful to get informative content and updates on various topics.
For organization (corporate)
Internal training use videos to help employees learn new skills or information. Creating step-by-step guides (tutorials) to help staff understand processes or tools. Also useful for walk-throughs which shows employees how to complete tasks or use systems through detailed video guide.
Video-on-demand (VOD) workflow:
Ingestion: Content providers upload pre-recorded videos to the VOD platform. Metadata (such as titles, descriptions, and categories) is associated with each video. Videos are transcoded into various formats suitable for different devices (e.g., smartphones, smart TVs).
Storage: Transcoded video files are stored in a content repository. Content delivery networks (CDNs) cache popular videos closer to viewers for efficient delivery.
User authentication and authorization: Users sign in to access the VOD service. Authorization ensures that users can only view content they are allowed to access.
Content Delivery: When a user requests a video, the VOD system retrieves the relevant file from storage. CDNs distribute the video efficiently to minimize latency.
Playback:The video player decodes and renders the video stream. Users can control playback (play, pause, seek) using familiar controls.
Analytics and recommendations:The VOD platform collects data on user behaviour (views, likes, watch time). Algorithms analyse this data to provide personalized recommendations.
APIs for VOD (Video on demand)
VOD API
A VOD API allows developers to manage video content libraries, enabling uploads, transcoding, playback control, and metadata management for on-demand videos. This API is essential for organizations offering video streaming services like Netflix or Hulu.
Content management API
Manages video content by enabling users to upload, store, and organize videos on the platform. This API allows users to add metadata such as titles and descriptions and categorize content for better organization.
Examples: Vimeo API, Brightcove API, Kaltura API.
Video transcoding API
Converts video files into multiple formats and resolutions to ensure compatibility across devices like mobile phones, desktops, and smart TVs. For instance, users can upload a high-definition video, and the API will transcode it into formats like 1080p, 720p, and 480p for optimized viewing.
Examples: AWS Elemental MediaConvert, Zencoder API, Bitmovin API.
Content delivery API (CDN integration)
Enhances global video delivery by utilizing Content Delivery Networks (CDNs) to cache content closer to end-users, minimizing latency and ensuring smoother playback. This improves video accessibility and reduces buffering, especially for users in different regions.
Examples: Cloudflare Stream API, Akamai CDN API, Fastly API.
User authentication and authorization API
Controls user access to specific content by ensuring only authorized users can view certain videos, often based on subscription levels or permissions. This secures video content, restricting access to appropriate users.
Examples:Auth0 API, Okta API, Firebase Authentication.
Playback API
Manages the streaming and playback of video content, offering features like play, pause, fast-forward, and rewind. This API allows video players to be embedded into websites or apps, providing full control over the playback experience.
Examples:JW Player API, Video.js API.
Analytics API
Tracks user interaction with video content, including views, watch time, likes, and recommendations. This data helps in understanding user behaviour and optimizing content strategy to improve engagement.
Examples:Google Analytics API, Wistia API, YouTube Data API.
Different types of VOD
VOD has gained momentum in recent years. Increasingly, consumers prefer to watch video on personal and mobile devices. Since cinemas were closed during the COVID-19 pandemic, many potential movie blockbusters went directly to VOD so that viewers could stream the movie of their choice on demand in the safety of their homes. Some of the examples include Amazon Prime, Netflix, YouTube etc.

What is Live streaming?
Live streaming allows you to watch events in real-time over the internet, much like tuning in to a live sports game or concert as it unfolds. It involves broadcasting video and audio content instantly to viewers, providing an interactive and engaging experience. Unlike pre-recorded videos, live streaming delivers events as they happen, enabling audiences to participate and respond in real time.
With Live streaming, you:
- Watch in real-time: The content is happening live, and you see it as it unfolds.
- Join live events: Participate in live events like sports games, news broadcasts, or interactive shows.
- Limited control: You usually cannot pause or rewind the stream. You get what is happening right now.
Technical aspects of live streaming
Encoding:Encoding converts live video into a digital format suitable for streaming. Tools like OBS Studio, Wirecast, and FFmpeg are commonly used, along with protocols such as RTMP for ingesting and HLS for delivery. Proper encoding ensures high video quality across various platforms and devices.
Streaming: Streaming involves broadcasting the live feed through services like YouTube Live or Twitch. Developers integrate with these platforms, APIs to manage streams and use protocols like RTMP and HLS to deliver content efficiently, minimizing buffering.
Content Delivery Network (CDN): CDNs distribute the stream globally, reducing latency and handling high traffic loads. This enhances stream delivery speed and improves the viewer experience.
APIs and SDKs: Integration involves using APIs from platforms like YouTube live API or Twitch API for stream management, and SDKs like JW Player or Video.js for embedding and controlling playback in apps or websites.
Security:Protect live streams with encryption methods such as RTMPS or HLS with AES. Implement authentication to restrict access to authorized viewers, preventing unauthorized use and piracy.
Latency management:Minimize delay with low-latency protocols like Low-latency HLS or WebRTC to ensure streams are as close to real-time as possible, which is crucial for live events.
Error handling: Develop error recovery strategies, including automatic reconnections and fallback servers, to maintain stream stability and quickly address issues.
UI design and mobile optimization:Design engaging interfaces with features like live chat and interactive overlays. Ensure streams are optimized for mobile devices with responsive design and thorough testing.
Testing and debugging:Conduct pre-stream tests, simulate high traffic, and use monitoring tools to identify and fix issues, ensuring a smooth streaming experience for viewers.
APIs for live streaming
Live streaming API: Live streaming APIs allow developers to initiate, control, and monitor live broadcasts. These APIs, provided by platforms like YouTube Live or Twitch, enable integration with third-party apps for managing streams, scheduling broadcasts, and accessing viewer analytics.
Different APIs are used for Live streaming to manage and deliver content effectively. Here's an overview of the APIs used for each type:
Live stream encoding API
