What is DirectShow?

DirectShow is a multimedia framework developed by Microsoft for Windows. It enables the playback, capture, and processing of audio and video streams¹. DirectShow works behind the scenes in media players, editing software, and streaming applications, connecting various components like codecs, filters, and hardware to ensure smooth multimedia handling.

What is Video Compression and Deblocking?

Video Compression:
To reduce file sizes, videos are compressed using algorithms like H.264, H.265, or VP9. These techniques break a video into smaller sections called blocks and only store essential data, discarding redundant information².

The Problem—Compression Artifacts:
Compression can leave behind visible flaws, called artifacts, that appear as blocky or pixelated areas in the video, especially in low-bitrate files. These artifacts are most noticeable in scenes with motion or large areas of similar colors (e.g., skies or walls).

Deblocking:
Deblocking refers to techniques used to reduce or eliminate these artifacts.
Traditional Methods:
Most traditional deblocking filters work by smoothing out the edges between blocks or blending the colors. However, these methods often result in blurry visuals and fail to preserve fine details.
