Description	🔵 M4S, a format specifically designed for storing video segments in streaming services, has a unique structure. Though based on the MP4 structure, this type of file segments content into smaller chunks for more flexible buffering. Additionally, M4S can efficiently transfer audio and video streams with minimal lag. This makes it easier to adapt to varying internet speeds and enhances the overall playback quality.
Technical details	🔵 It's important to remember when dealing with M4S files that each segment contains only a portion of the video. This allows the player to dynamically select the appropriate bitrate. Along with this, the format also includes metadata about duration and indexes, which facilitates quick switching between fragments. M4S ensures the synchronization of audio and video, contributing to stable playback.
