Last updated: 2024-12-03 15:11:36

    Overview

    CSS can record live streams so that they can be played again on demand. You can also perform operations such as transcoding, screencapturing, watermarking, and encryption on the recording files.
    Strength
    Description
    Quick
    CSS provides a one-stop, reliable, and smooth live-to-VOD solution. With simple configurations, you can record and store live streams in the cloud.
    Efficient
    CSS offers high-availability services and can handle high concurrency. It supports multi-channel streaming, real-time monitoring, and preview, allowing for efficient management of live rooms.
    Together with the video processing and acceleration capabilities of VOD, CSS has built an integrated, efficient, and easy-to-use live recording solution.
    Cross-platform compatibility
    Recording files can be transcoded in the cloud into formats suitable for playback on a wide range of platforms, including iOS, Android, web, and HTML5. They can also be distributed via VOD platforms like Tencent Video to attract more views.
    Diverse use cases
    Live recording integrates the core capabilities of CSS and VOD and is suitable for various application scenarios such as live sports editing, live class distribution, and video moderation.

    Use Cases

    Live recording is suitable for many industry-specific scenarios such as enterprise live streaming, ecommerce live streaming, and education live streaming.
    Use case
    Description
    Live streamed classes
    Live classes, such as courses offered by online tutoring platforms and employee training given by enterprises, can be recorded. The recordings can be archived, encrypted, replayed, or streamed again in the form of pseudo-live streaming.
    Media live streaming
    Live streams can only be watched in real time. In order to distribute the content again, platforms need to record live streaming sessions. It’s also necessary to record live streams and retain the recordings for post-streaming moderation.
    CSS provides pseudo-live streaming and other solutions to meet such needs.
    Game/Sports live streaming
    Such scenarios have the following challenges:
    The time when events will be live streamed may change, so viewers may not be able to conveniently watch entire events.
    Viewers want to rewatch events after the live stream ends.
    It may be necessary to generate highlight clips from a live stream, enable time shifting during live streaming, or cut a live stream into multiple segments.
    The live recording solution of CSS supports the following features:
    You can quickly configure global or real-time recording of live streams either in the console or by calling APIs.
    Recordings of live streams in HLS format can be time-shifted, enabling viewers to replay earlier parts of the live stream.
    Video AI capabilities enable quick clipping, processing, and delivery of VOD files, so that video content can be released and spread more efficiently.
    Ecommerce live streaming
    Merchants' live product introductions are recorded so that shoppers late to the live streaming can rewatch the introductions any time.
    SDKs are provided for different platforms to help merchants quickly set up live streaming for shopping. The on-cloud recording feature enables them to quickly record the live streams of product presentations, and the time shifting feature allows shoppers to watch previous parts of the live stream.
    After a live shopping session ends, the recording file can be quickly transcoded and distributed again.
