Introduction

Today, video streaming platforms constitute a significant portion of internet traffic. Major players like Netflix, Amazon Prime Video, and YouTube serve petabytes of data to billions of users every day. Investing in new technologies to ensure efficiency at this scale and maximize user experience is inevitable.

AV1 (AOMedia Video 1) is one of the most important technological developments in this field. Developed by the Alliance for Open Media, formed by technology giants including Google, Mozilla, Microsoft, Amazon, and Netflix, this open-source video codec can offer 30-50% more efficient compression rates compared to H.265/HEVC. This article covers all stages of building a premium video streaming platform using AV1 and Amazon AWS services.

AV1 Codec: Next-Generation Video Compression

AV1 is a royalty-free codec that stands out among high-efficiency video coding standards. It performs better than common codecs like H.264 and even HEVC (H.265), especially for high-resolution content such as 4K and 8K.

Advantages of AV1

• Higher Compression Efficiency: 30-50% less data usage at the same visual quality
• Royalty-Free Licensing: Cost advantage in terms of copyright
• HDR and Wide Color Gamut Support: Richer visual experience
• Superior Performance in Low Bandwidth Conditions: Quality streaming even with weak internet connections
• Increasing Device Support: Native support in modern browsers and next-generation mobile devices

These advantages translate to significant cost savings and user experience improvements, especially for streaming platforms operating at a global scale.

Platform Architecture with Amazon AWS and AV1

Amazon’s cloud services ecosystem provides an end-to-end integrated solution for creating a Netflix-like platform. Combined with AV1 support, these services form an ideal infrastructure for a modern streaming platform.

Core Architectural Components

The basic architecture of an AV1-based streaming platform using Amazon AWS consists of the following components:

1. Content Storage: Amazon S3
2. Video Processing and Transcoding: AWS Elemental MediaConvert
3. Content Delivery Network: Amazon CloudFront
4. Live Stream Processing: AWS Elemental MediaLive
5. User Database and Identity Management: Amazon Cognito and DynamoDB
6. Backend Services: AWS Lambda, API Gateway
7. Analytics and Recommendations: Amazon Personalize and Amazon Kinesis

Figure 1: AV1-Based Streaming Platform Architecture

As shown in Figure 1, the platform’s architecture covers all processes from content preparation to delivery to the user. This architectural structure leverages AWS’s integrated services to provide scalability and high performance.

Content Preparation and Encoding Strategy

Preparing and encoding video content in AV1 format is one of the most critical processes of the platform. Since high-quality AV1 encoding can be demanding in terms of processing power, creating an effective strategy is important.

Content Processing Workflow

1. Source Content Acquisition: Obtaining a high-quality master copy (ideally ProRes or DNxHR)
2. Quality Control and Pre-processing: Noise reduction, color correction, audio normalization
3. AV1 Encoding: Encoding at various quality levels using AWS Elemental MediaConvert
4. ABR Packaging: Adaptive bitrate packaging in DASH and HLS formats
5. Metadata Enrichment: Adding subtitles, multi-language support, chapter markers

Optimal Encoding Parameters

AWS Elemental MediaConvert allows you to effectively configure the following parameters for AV1 encoding:

• Multiple Resolution Profiles: 4K, 1080p, 720p, 480p, 360p
• Bitrate Strategies: VBR (Variable Bit Rate) or QVBR (Quality-Defined Variable Bit Rate)
• Sharp/Slow Preset Balance: Optimal balance between processing time and quality
• 2-Pass Encoding: Use for critical content requiring higher quality

Figure 2: AV1 Encoding and Distribution Workflow

As shown in Figure 2, different processing paths are followed depending on the content type. Batch processing is used for VOD (Video on Demand) content, while a real-time processing approach is applied for live broadcasts. Additionally, factors such as the user device’s AV1 support and connection quality determine the quality of the video stream provided.

Distribution Infrastructure and CDN Optimization

Content distribution is a critical component that directly affects the user experience. Amazon CloudFront can provide low-latency content distribution on a global scale.

CDN Configuration and Optimization

• Edge Location Strategy: Prioritized edge locations based on user density
• Origin Shield: An additional caching layer to protect S3 resources
• Cache-Hit Optimization: Effective caching policies and expiration strategies
• Geographic Restrictions: Regional access control according to content licensing requirements
• HTTPS and Secure Content Delivery: DRM integration and secure transfer

Multi-CDN Strategy

To reduce the risk of dependency on a single CDN:

• CloudFront as Primary: Basic distribution infrastructure
• Alternative CDN for Failover: Akamai or Fastly integration for redundancy
• Dynamic CDN Routing: Intelligent CDN selection based on performance metrics

User Experience and Player Integration

The user interface and player technology are the “visible face” of the streaming platform and play a critical role in user satisfaction.

AV1-Compatible Player Options

• Web Platform: Shaka Player, Video.js, or Amazon IVS Player
• iOS Applications: Customized solutions with AVPlayer
• Android Applications: ExoPlayer with AV1 support
• Smart TV and OTT Devices: Customized players with device-specific SDKs

Player Features

• ABR (Adaptive Bit Rate) Smart Transitions: Seamless quality adaptation based on network conditions
• Caching and Preloading Strategies: Providing a smooth viewing experience
• Interactive Features: Skip, fast-forward, rewind optimizations
• Subtitle and Accessibility Features: Compliance with WebVTT and other standards

Figure 3: AV1 Video Viewing Sequence Diagram

As shown in Figure 3, the user’s video viewing experience involves a complex series of interactions. When the user opens the application, many systems work together in the background to ensure the content is presented optimally. This sequence diagram shows how content is delivered with AV1 or alternative formats from the moment the user presses the “Play” button.

Scaling and Cost Optimization

Both cost management and scalability are critical for a streaming service operating at a global scale.

Scaling Strategies

• Horizontal Scaling: Automatic response to demand increases with AWS Auto Scaling groups
• Regional Optimization: Regional infrastructure distribution based on user density
• Serverless Architecture: Backend services that grow as needed with AWS Lambda
• Multi-Region Architecture: Active-active configuration for high availability

Cost Optimization Approaches

• Selective Use of AV1: Prioritizing content with high viewing rates rather than all content
• Using Spot Instances: Cost-effective resource utilization for encoding operations
• Content Lifecycle Management: Moving less-viewed content to more cost-effective storage tiers with S3 Intelligent-Tiering
• Traffic Optimization: Reducing bandwidth costs with caching strategies

Figure 4: AV1 Cost and Savings Analysis

As shown in Figure 4, although AV1 encoding cost is higher, the savings in CDN and storage costs balance the total cost, especially for content with high viewer numbers. This graph shows the break-even point that will help you determine the optimal encoding strategy for your broadcasting platform.

Challenges and Solution Strategies

Challenges that may be encountered when building an AV1-based streaming platform and suggestions for overcoming them:

Technical Challenges
