No there isn't. V4L2 is a kernel/userspace interface and doesn't provide video 
format conversion.

There are probably YUYV to RGB converters in major codec libraries and/or in 
webcam applications.

Lots of people have stated their interest for a userspace V4L2 library which 
would handle simple video format conversions. Unfortunately, nobody has 
implemented it yet. Wanna have a go ? :-)
