Detailed Description

Vendor-neutral GPU-decoder selection keyed on VideoPixelFormat.

The capture-side symmetric counterpart to encoders/WireEncoderFactory.hpp: turns "the on-wire pixel format a card delivers" into the GPUVideoDecoder that unpacks those bytes into RGBA at sample time. The switch lives here so that a capture-card addon (AJA, and future DeckLink/Bluefish/Magewell/Deltacast) only has to map its vendor enum -> VideoPixelFormat.

Returns nullptr for formats with no capture decoder yet. The decoder allocates an input texture sized to the wire byte layout (the strategy DMAs into it); meta carries the VPID/InfoFrame-derived colour metadata.
