What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
First of all, visit the FreeBSD WebcamCompat page to check that your TV Tuner device is supported. Most popular webcams are compatible. Then follow the instructions on this page to install the webcamd program.
In some fewer cases, you may own a compatible PCI card, which is recognised by the system as a native PCI device. Those devices need their own special kernel module, and do not use webcamd at all. For example the Hauppauge WinTV HVR-4000. Which require the cx88 kernel modules to be loaded. You will instead need to follow the steps here for installing the cx88 device driver.
Most of these commands can just be copy-pasted. The webcamd program must be installed directly in Finch's chroot. This is because webcamd needs to create new device nodes e.g. /dev/dvb, etc. in '/dev/'. Such special files require 'mknod' cmd. That can't be created in a jail.
