Frame-by-Frame AVI Video Playback Using MATLAB GUI

This documentation elaborates on the technical implementation details for frame-by-frame video playback functionality. The system utilizes MATLAB's GUI development environment to create an interface that decomposes AVI-format videos into individual frames for sequential display. Key implementation aspects include employing MATLAB's VideoReader function to load and process AVI files, while using a frame counter variable to track current playback position. The GUI incorporates dedicated control buttons for: 1) Pausing/resuming playback using conditional loop structures, 2) Navigating to previous frames through frame index decrementation with boundary checking, and 3) Advancing to subsequent frames via index incrementation. This frame-accurate control mechanism allows users to precisely manage video progression and perform detailed frame-level analysis, making it particularly valuable for applications in video editing workflows, computer vision research, and academic image processing studies. The implementation typically involves callback functions for each control element, frame buffer management for efficient navigation, and timestamp handling for synchronization accuracy.
