I've posted an updated cx88 snapshot at ftp://corona.homeunix.net/cx88_20071215.tar.gz
Here are the changes since the 20071022 snapshot:
--Kernel modules now require FreeBSD 7.0. If you're running 6.x, you should
still be able to use the new libtuner and cx88 app with the kernel modules
from the 20071022 snapshot. With the new kernel modules, the iicbus patch is
no longer necessary.
--Includes Richard Airlie's excellent cx88ir driver for infrared remotes.
--Adds final support for Hauppauge WinTV Nova-T PCI, which brings in new
libtuner drivers for the Thomson DTT75105 tuner and Conexant CX22702
--Numerous changes to cx88 app:
--The XML configuration file can optionally contain a new <config> section
with the following subtags (look at the included cx88.xml for
-- <libtuner> Allows libtuner configuration to be embedded in XML file. You
can still optionally specify a normal text file with the -t option.
-- <alias> Allows more convenient names for frequently used channels
-- <default> Specifies a channel to be used at startup if
the -c option is omitted.
--In interactive mode, you can now specify the following in addition to
normal channel numbers for the 'c' option:
--An alias name from the XML config file
--'default': Select the default channel from the XML config file
--'first': Select the first channel from the current profile
--'last': Select the last channel from the current profile
--'up': Move up a channel. If the current channel was selected using an
alias, this will move the next channel in the list of
aliases. Otherwise, it will move to the next numerically
higher channel in the current profile.
--'down': Works the same way as 'up', but traverses the channels in the
--In interactive mode, you can scan all channels in the current profile for
available signals, using the 's' option. You'll be prompted for a minimum
signal strength threshold (as a percentage).
--In interactive mode, you can stop and re-start the capture using the 'h'
option. When the capture is stopped, the cx88 device may be used by other
--The app now supports the '-m' command-line option for specifying the MTU
(in bytes) for UDP captures. If not specified, a default of 1500 is used.
This option may be specified more than once, and each -m option applies to
all subsequent -u options until the next -m option.
--The app now supports the '-b' command-line option, which works in basically
the same way as the -m option, except that it specifies the internal
memory cache size for file captures.
--The app now supports the '-h' command-line option, which (in interactive
mode only) allows it to be invoked without actually starting a capture.
The capture may be started at any time using the 'h' interactive command.
--The app now supports a remote control interface, in interactive mode only.
If you specify a port number using the '-p' command-line option, the app
will listen for a TCP connection on the specified port. A separate remote
control app can then connect to this port and issue commands to the cx88
app. The commands must be sent as null-terminated strings, and are in
basically the same format as keyboard-interactive commands. Here are some
Operation Remote control command string
Move down a channel cdown\0
Select channel 63 c63\0
Select channel (alias) NBC cNBC
Scan w/ strength thresh. of 45% s45\0
Display info i\0
Stop (or re-start) capture h\0
The app can still be used in normal keyboard-interactive mode while a
remote control client is connected. However, the app currently only
supports one remote control client at a time. If a second client connects
to it, the first client will be disconnected.
