Hi Oliver, SDR++ is one popular project that pulls from these binaries. The issue only came up just now because Blog V4L (Lite) support wasn't working after they updated to the latest build from the ftp. It must have been working back in 2023, because that's when Blog V4 support was added, and the binaries have picked up that change. So probably only 2-3 years that it has been failing.

Hi,
I've just been testing out the latest Windows builds at https://ftp.osmocom.org/binaries/windows/rtl-sdr/, but they do not seem to be up to date.
I tested the latest October 18 2026 zip file, and found that rtl_test does not detect the RTL-SDR Blog V4L.
But if I compile from source from the Osmocom rtl-sdr GitHub, I get working V4L support for Windows and Linux, so the source is working fine.
So it seems that the automatic builds are not working correctly and are using old code to build librtlsdr.dll and possibly everything else?
