That patch set contains libv4lconvert conversion for all SDR formats I have currently available. Also simple test app to stream data from device to standard output. Seems to works very well. CPU usage is something like 13% when 2MSps sampling rate is used, which goes very much from the runtime float conversion. Using pre-calculated LUTs will reduce CPU usage very much, but lets that kind of optimizations be another issue.
