Scenarios

Scenario 1: Sliding and loop playback of short videos

[Description]
For short videos, highlights are often displayed in full-screen sliding mode. ApsaraVideo Player SDK supports view size customization to play videos in full screen. It also supports multi-player, automatic playback, and pre-loading functions, allowing you to easily watch multiple videos in full-screen sliding mode. Featuring short and refined content, a short video is usually played in loop playback mode. To save your traffic and ensure seamless loop playback, ApsaraVideo Player SDK provides play-and-cache and loop playback operations to meet business demands.

[Procedure]
Record a short video by using the short video SDK and upload it to ApsaraVideo for VOD by using the upload SDK. Use the advanced framework of ApsaraVideo Player SDK to enable the play-and-cache and loop playback functions. Then, you can play a short video in full-screen sliding mode and loop playback mode.

Scenario 2: Video copyright protection

[Description]
Nowadays, people have higher awareness and requirements on video copyright protection. If you want to build an education video website with video courses from teachers and only open the courses to premium users, you must protect your videos from being pirated. ApsaraVideo Player SDK provides multiple protection functions: 1. Hotlinking protection. This function allows only whitelisted users to access your resources. 2. URL signing. This function ensures that only the videos within their authentication validity period can be played. 3. Encrypted streams. This function ensures that the videos can only be played by using the ApsaraVideo Player SDK. 4. Secure download. This function ensures that the downloaded videos can only be played by the application (with a unique bundle ID or signature) specified in the console.

[Procedure]
Enable hotlinking protection and URL signing in security settings in the ApsaraVideo for VOD console. Enable encryption in the transcoding settings. Enable secure download in download settings and generate an encryption key. Integrate the encryption key into ApsaraVideo Player SDK and use its advanced framework to download and play videos.

Scenario 3: Data-driven operation

[Description]
Data reflects the most real conditions of users and products. Through data analysis, you can optimize products, direct business development, improve the conversion rate, and establish a decision-making basis. ApsaraVideo Player uses service clients to collect data and provide real-time user feedback. It provides data isolation and confidentiality functions to ensure that the data generated for a user only serves the user.
