Extracting audio from all CFA video files in one command.

Really impressed with myself today.
I have the CFA schwsere CDs with me and these CDs have vidoes in them, but I am not interested in looking at a person talking, I am more interested in listening to the lecture. In short I would like to extract the audio channel for all these videos.
1. Find a tool that extracts audio from the vidoe file - ffmpeg, this tool was able to extract the audio as an mp3 file.
2. Automate the process to go over all the vidoe files and convert them to mp3.

Since all the video files have the same name, and I want the audio file to have diffent names based off the Study Session and Reading, here is what I did
- Find all wmv files
- for each file extract the folder name ( this contains the following format L2_SS18_P7)
- extract the video into an audio file based off the above file name.

find . -name *.wmv -exec sh -c 'ffmpeg -i {} `ls {} | cut -d '/' -f 3`.mp3' \;

Whoo hooo

I found that CD10 and CD11 are the same, so I have to mount and extract them again.


Intermediate commands to test
find . -iname *.flac -exec flac2vorbis {} \; -exec rm -v {} \;


find . -iname *.flac -exec sh -c "flac2vorbis {} && rm {}" \;


find . -name *.wmv -exec sh -c "ls {} | cut -d '/' -f 3" \;


ffmpeg -i ./CD16/L2_SS18_P7/L2_SS18_P7_files/0MM0.wmv `ls ./CD16/L2_SS18_P7/L2_SS18_P7_files/0MM0.wmv | cut -d '/' -f 3`.mp3

Connecting from Mac (mini) and Linux (Ubuntu) through Citrix to my work desktop

I have been trying to connect (through Citrix) to my desktop at work through my home machine, Ubuntu 8.04 (Linux) and Mac Mini.

On the mac I installed the Citrix client, but on connecting to the server I got the following error

SSL Error 0: YOu have not chosen to trust "/C=US/ST=

/L=/O=Verisign, Inc./OU=Class 3 Public Primary Certification Authority/CN=", the issuer of the server's security certificate.

Error number 183

I remembered getting a similar error while connecting from Linux but all that I could recollect that it was related to some missing certificates.

I logged into my Linux box and copied over the following certificates

EquifaxSecureeBusinessCA-1.crt
EquifaxSecureGlobaleBusinessCA-1.crt
BuiltinObjectTokenEquifaxSecureeBusinessCA2.crt
BuiltinObjectTokenEquifaxSecureCA.crt

from the following Linux folder
/usr/lib/ICAClient/keystore/cacerts/
to the following mac folder
/Applications/Citrix ICA Client/keystore/cacerts


Actually I just one certificate, and I can get it from here
http://www.geotrust.com/resources/root_certificates/certificates/Equifax_Secure_Certificate_Authority_DER.cer

I got this information from here : http://blandname.com/2008/11/10/you-have-not-chosen-to-trust-equifax-secure-global-ebusiness-ca-1/
