Broadcast: HD Video Ingest

I recently saw this application at a customer’s site and had the chance to take it for a test drive. Pretty sweet if you ask me.

So if you find yourself in a production broadcast environment and you need to ingest some content off digibeta using your £20,000 Sony VTR but instead of also occupying an Avid Editing suite or forking out £20,000+ for an Amberfin iCR have a look at Miura from BlueLucy Media.

Their slick application makes use of the Decklink HD Extreme PCIe Capture Card to ingest (capture) HD video to a variety of formats (MPEG2, MPEG4, MXF OP1a, IMX50). The great thing about this app is that it can also create a low resolution proxy version at the same time (WMV, Flash, H.264, etc…).

Software and bundled Decklink HD capture card costs £4700 – an amazing price considering the alternatives. They recommend a medium to high spec quad core Xeon HP workstation for capturing HD content which they estimate at costing another £2000-3000 (but I believe at today’s prices – Dec 2009 – you could pick up a good workstation to do the job for under £1000.)

Windows 7 install from USB stick

Microsoft has released a little utility to help get Windows 7 on to your netbook – so it can run like a dog. Appropriately named Windows7-USB-DVD-Download-Tool-Installer-en-US.exe is available for download from codeplex.com

You obviously need to get your hands on the Windows 7 iso and have a USB stick large enough to hold said iso.

Windows 7 & Vista “GodMode”

January 23, 2010 1 comment

Windows 7 32bit + 64bit, Vista 32 bit ONLY

Do Not Use in Vista 64bit
If you create the folder it will send Explorer into a crash loop that you can recover by entering Safe Mode command prompt, navigating to the parent folder of the god mode folder and executing rd /s God[Tab]

Create “GodMode” folder:
All you have to do is create a folder and name it GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} or
anything.{ED7BA470-8E54-465E-825C-99712043E01C}

The resulting folder looks like the photo below

Linux: creating a cron entry

Launches your default editor – most likely vi – and edits your crontab file which ends up in /var/spool/cron/username
crontab -e

I always add this as my first line as I can never remember which order they go in.
#min hour daymo month daywk cmd

And now a sample cron entry which will run awstats every day at 6:05am
05 06 * * * /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.website.com

Use the following to list your crontab file
crontab -l

Linux: Creating sendmail.cf using m4

After modifying the sendmail.mc on a Linux mail server your need to recreate the sendmail.cf file.
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf


Provided that /etc/mail/sendmail.mc has the following lines at the top:

dnl ### Include default Sendmail cf file
include(`/usr/share/sendmail-cf/m4/cf.m4')dnl


Other wise you need to include it on the command line:

m4 /usr/share/sendmail-cf/m4/cf.m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf


Now if you don’t get any errors from the previous command issue the following to restart sendmail:

/etc/init.d/sendmail restart

Disabling Autoplay or Autorun in Windows

There may be several reason why you may wish to disable Autoplay or Autorun for CD, DVD, and removable drives in Windows but for me it’s partly security and partly annoyance. There have been a few recent worms that use autoplay to silently install themselves and replicate. The viruses add themselves to autorun.inf which Windows happily parses and executes shellexecute commands or changes the behaviour when a users double clicks on the removable media.

For those curious how the viruses take advantage of the autorun feature check out technical details from McAfee and TrendMicro.

Howto Disable Autorun on Windows XP:

For a single machine you can use TweakUI to disable autoplay http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx

From: http://www.bleepingcomputer.com/forums/topic93897.html

The easiest way to disable Autorun on a specific drive is to download and use Tweak UI PowerToy.

  • After installation, launch Tweak UI, double-click on My Computer in the tree menu on the left, then click on AutoPlay > Drives. This will allow you to change the system settings for AutoPlay/autorun.
  • Uncheck the drives you want to disable AutoPlay on and click on Apply.
  • Next, click on the Types in the left tree. This allows you to control whether Autoplay is enabled for CD and DVD drives and removable drives. You may need to restart Tweak UI if it closes after step 2.
  • Uncheck the box to disable Autoplay for a particular type of drive.
  • Click Apply.

 
Or for those wishing to disable Autorun on several computers you can disable Autorun by Domain Policy aka Group Policy.

Howto Disable Autorun on Windows XP using Domain Policy (Group Policy):

After launching “gpedit.msc” or from within Active Directory, Enable the Turn Off Autoplay option in both
