This fork has no special differences from the original, only added support for building using CMake.
And some small changes.
rtltcpaccess is a drop-in replacement for RTL283XACCESS.dll that connects to an rtl_tcp server and streams the samples from there. Its main purpose is to allow DAB reception on GNU/Linux and OS X through running the Windows software in Wine, but it works on Windows as well.
The installation script (dab_install.sh) fetches the DAB software as well as a pre-built version of the library which is also available from here:
https://github.com/Mr-Precise/rtltcpaccess/releases/latest
To get the installation script, run:
wget https://raw.github.com/Mr-Precise/rtltcpaccess/master/res/dab_install.sh
chmod +x dab_install.sh
./dab_install.sh
If you want to build the library yourself, get MinGW and run 'make' or use CMake
Just run rtl_tcp (which comes with librtlsdr). Since the default auto-gain setting doesn't always result in the best SNR, you might want to play with the gain option [-g]. When rtl_tcp is running, start the DAB application.
By default, rtltcpaccess tries to connect to localhost:1234, you can change this by creating a key in the Wine registry:
wine regedit
Those are the names of the registry keys:
[HKEY_CURRENT_USER\Software\rtltcpaccess]
"address"="192.168.1.1"
"port"=dword:00009999
"testmode"=dword:00000000
Calculate new port:
run in console
echo -n "Enter new port: "; read port; printf "New DWORD value: %08x\n" $portaddress is a string, port is a DWORD. If the testmode is enabled it checks for lost samples, just like rtl_test.
