RipCode builds video transcoding device on Linux base
08-06-2008 01:00 PM
When RipCode decided to build a video transcodingdevice three years ago, it used MontaVista Linux Professional Edition, a platform designed for developers who want all the benefits of an open source development environment.
Hello everyone, I've made a script and I want to share and get new ideas for improving it. So far, the script
1. Searches a directory tree for MP3 files;
2. Check their bitrates;
3. Change any bitrate higher than 128 kbps to VBR 4
(It ignores files with a bitrate lower or equal to 128, as... (3 Replies)

I have a network consisting of Linux Server, Win-Nt & 95 OS. I am able to connect from Linux to Win-NT using either ftp / telnet in time. But it takes me around & more than 50 seconds to connect from Wint -Nt/95 to Linux using either ftp/telnet. My network is small & it hardly consists 20-25... (3 Replies)
ACPI_VIDEO(4) BSD Kernel Interfaces Manual ACPI_VIDEO(4)NAME
acpi_video -- ACPI Video Extensions driver
SYNOPSIS
device acpi_video
DESCRIPTION
This driver uses the ACPI Video Extensions to control display switching and backlight brightness. The availability of the sysctl(8) vari-
ables depends on the functions offered by the host's ACPI implementation.
SYSCTL VARIABLES
The following sysctls are currently implemented, where <device> is crt, lcd, or tv:
hw.acpi.video.<device>.active
Current state of the output device.
hw.acpi.video.<device>.levels
List of supported brightness levels.
hw.acpi.video.<device>.brightness
Current brightness level of the device.
hw.acpi.video.<device>.fullpower
Preset brightness level to be used in full power mode.
hw.acpi.video.<device>.economy
Preset brightness level to be used in economy mode.
Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.
SEE ALSO acpi(4), loader.conf(5), sysctl.conf(5), sysctl(8)HISTORY
The acpi_video driver first appeared in FreeBSD 5.3.
AUTHORS
The acpi_video driver was written by Taku YAMAMOTO <taku@cent.saitama-u.ac.jp>. This manual page was written by Mark Santcroos
<marks@ripe.net>.
BUGS
Some systems only perform output switching via SMM even though they export the proper information via ACPI. On such systems, the proper
hotkeys or OEM driver (for example, acpi_toshiba(4)) must be used instead.
