TODO

• Adjust width and height of capturing frame.

• A producer/consumer thread splitting.

• Custom ASCII charset via config file

• Brightness/contrast adjustment.

• Reverse video - Invert brightness \rightarrow charset mapping

• Color output - Extract U/V channels, map to ANSI/RGB codes

• Add feature to record and save it in popular video formats like .mp4, .mov and .gif.

• Dithering effect.

• Sobel edge detection (kernel convolution). Algorithm reference: https://homepages.inf.ed.ac.uk/rbf/HIPR2/sobel.htm

• SIMD for YUYV to grayscale coversion.

• Hot-reloading plugin system

• Analyzing frames for what changed (inter-frame compression)

• Temporal Compression

• Lookup Table (LUT) Cache Optimization

• Migrate from C to Cpp after, I consider, I have done enough optimisation in C.
