Nvtv can enable, activate and configure the TV output of most NVidia cards, and some others, such as some 3dfx ones. Nvtv probes and uses the PCI bus directly, thus does not need any kernel support, and allows a very low-level access to the multiple TV encoder chips supported. Then you have a direct control over the registers of the chip, and can use all the resolutions and sizes the board supports. Most of the accesses done by Nvtv need root privileges, and a daemon is provided to allow non-privileged users control the TV output of the graphics card.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
