zvbi-chains — VBI proxy wrapper


zvbi-chains [ options ]


zvbi-chains is a small wrapper which executes the VBI application given on the command line while overloading several C library calls (such as open(2) and read(2)) so that the application can be forced to access VBI devices via the VBI proxy instead of device files directly.

LD_PRELOAD is used to intercept C library calls and call functions in the libzvbi-chain shared library instead. Parameters given on the command line (e.g. device path) are passed to the library by means of environment variables.


-dev path
Path of a VBI device from which to read data.
-debug level
Enables debug output: 0 = off (default); 1 = warnings, 2 = all messages.
Print a short description of all command line options.
