AI BriefingImplementing HLS-Based Short-Form Streaming: A Case Study in iOS/Android Compatibility
Key point
To deliver a seamless short-form experience on Olive Young's community app Shutter, the team adopted the HLS format and implemented a hybrid upload approach.
Details
In introducing short-form content to Shutter, Olive Young's SNS community, the team adopted the M3U8 (HLS) format to provide users with a seamless viewing experience. Compared to the existing MP4 approach, this reduced initial playback time by 60-70%, and secured stability through adaptive streaming (ABR), which adjusts video quality based on network conditions.
The video conversion process was automated using AWS Media Converter. When a user uploads an MP4 file, it is stored in S3, which then triggers Lambda to generate M3U8 playlists separated by resolution.
For the upload implementation, the team chose a hybrid approach that combines the flexibility of the web with the performance of native. Video compression and encoding are performed in a native environment capable of GPU acceleration to boost performance, while UI and upload logic are handled on the web to ensure flexibility in service operations. For web playback, the HLS.js library is used to support stable streaming across a variety of browser environments.
