A thirdparty provider can add their hardware support in the framework

oem A can add their card with hardware codec-B support
oem B can add support for converting their proprietery format-C to codec-B again using the framework

similarly for A1,A2...
codec-B1,codec-B2 etc

frameworkB component and frameworkA component (frameworkB can be dll,frameworkA maybe .sys)
