rustcv-backend-msmf/src/pixel_map.rs:38–53

Converts a Media Foundation GUID to a RustCV pixel format. This function maps Windows Media Foundation video format GUIDs to the cross-platform `PixelFormat` enum used by RustCV. # Arguments `guid` - The Media Foundation format GUID # Returns The corresponding `PixelFormat`. Returns `PixelFormat::Unknown(0)` if the format is not recognized, with a warning logged.
