Merging Video Segments to Cover a Time Range

Problem Overview Given multiple video segments from a sports event lasting T seconds, each segment is represented as [start, end]. These segments may overlap and have varying lengths. We can freely split and recombine segments—for instance, [0, 7] can be divided into [0, 1] + [1, 3] + [3, 7]. The objective is to recombine these segments to crea ...

Video Data Interconnect Interface Using SystemVerilog Interfaces

This design establishes a standardized, reusable video data interconnect interface using SystemVerilog interface constructs. It decouples timing-critical video signaling (e.g., sync pulses and pixel data) from functional blocks, enabling modular integration, scalable testbenches, and hardware-agnostic verification. Interface Definition: video_b ...

Optimizing FFmpeg Frame Extraction Through Strategic Seek Placement

Extracting individual frames from video files requires precise control over decoder initialization and timestamp seeking. The positioning of the seek flag directly dictates whether the process completes in milliseconds or requires full sequential decoding. Output format selection impacts both file size and processing overhead. Specifying -c:v m ...
