Recording aac native from your sound card v.2.0

Ok, I’ve got this, I think it’s better in quality.

ffmpeg.exe -y -rtbufsize 100M -f dshow -i audio=”Mezcla estereo (Realtek High De” -c:a aac -strict -2 -ar 44100 -ac 2 -b:a 192k “output.aac”

output.aac is put in ADTS container.

if you put output.m4a then ffmpeg saves it in different container.


Recording mp3 from your sound card

These are the steps
1. You have to install VLC
2. Activate the stereo mixer in the setting of sound of windows. It’s important.
3. Create a batch file like this:

vlc -I rc –rc-quiet -vv dshow:// :dshow-adev=”Mezcla estereo (Realtek High De” :live-caching=300 –sout “#transcode{vcodec=none,acodec=mp3,ab=192,channels=2,samplerate=48000}:std{access=file{no-overwrite,format},mux=mp3,dst=’D:\Downloads\sample-%%Y%%m%%d%%H%%M%%S.mp3′}”

‘dshow:// :dshow-adev=”Mezcla estereo (Realtek High De”‘ is my device of stereo mixer.
you have to enable format to be parsed the filename in dst field.
you can sweep out the argument -vv

if you want to know the list of devices in your Pc, you can type this:
ffmpeg -list_devices true -f dshow -i dummy

Dont use ffmpeg to recording from your sound card, it produces low level audio mp3.

Apparently, vlc uses ffmpeg libs in the conversions :/

If you want to recording into aac format ūüôā

vlc -I rc dshow:// :dshow-adev=”Mezcla estereo (Realtek High De” :live-caching=300 –sout “#transcode{vcodec=none,acodec=mp4a,ab=128,channels=2,samplerate=48000}:std{access=file{no-overwrite,format},mux=ts,dst=’D:\Downloads\sample-%%Y%%m%%d%%H%%M%%S.m4a’}” –sout-avcodec-strict=-2

Notes on openssl and keytool

Generate an plain pem file including the private and public key
openssl genrsa -out rsa-2048bit-key-pair.pem 2048

Generate an jks file including the private, public key and selfsigned certificate
keytool -genkey -keyalg RSA ‚Äďkeysize 2048 -alias rsa-2048 -keystore keystore.jks

Generate an encrypted pem file with passphrase from scratch - It's equivalent to create the "root key"
openssl genrsa -aes128 -passout pass:myP4ss -out rsa-2048bit-key-pair-encrypted.pem 2048

Generate an encrypted pem file with passphrase from plain pem file
openssl rsa -in rsa-2048bit-key-pair.pem -aes128 -passout pass:myP4ss -out rsa-2048bit-key-pair-encrypted.pem

Remove the passphrase and the encryption:
openssl rsa -in rsa-2048bit-key-pair-encrypted.pem -out rsa-2048bit-key-pair-nonencrypted.pem

Extract the public key:
openssl rsa -in rsa-2048bit-key-pair.pem -pubout -out rsa-2048bit-public-key.pem

what's inside the public key file
openssl rsa -noout -text -inform PEM -in rsa-2048bit-public-key.pem -pubin

what's inside the private key file
openssl rsa -noout -text -in rsa-2048bit-key-pair.pem

Creating an empty keystore jks
keytool -genkey -keyalg RSA ‚Äďkeysize 2048 -alias alias-example -keystore keystore.jks
keytool -delete -alias alias-example -keystore keystore.jks

Creating an empty keystore jceks
keytool -genseckey -keyalg AES -keysize 256 -alias alias-example -storetype jceks -keystore keystore.jck
keytool -delete -alias alias-example -storetype jceks -keystore keystore.jck

Convert pem file into DER format
openssl pkcs8 -topk8 -nocrypt -in rsa-2048bit-key-pair.pem -inform PEM -out rsa-2048bit-key-pair.der -outform DER

Convert PEM formatted public key to DER
openssl rsa -pubin -inform PEM -in rsa-2048bit-public-key.pem -outform DER -out rsa-2048bit-public-key.der

Generate a Self-Signed Certificate from an Existing Private Key
openssl req -key rsa-2048bit-key-pair.pem -new -x509 -days 365 -out self-signed-certificate.crt

Generate the CSR
openssl req -new -sha256 -key rsa-2048bit-key-pair.pem -out certificate-signing-request.csr

Generate the PKCS 12 file using your private key and CA self signed certificate of it
openssl pkcs12 -export -in self-signed-certificate.crt -inkey rsa-2048bit-key-pair.pem -certfile self-signed-certificate.crt -out rsa-2048bit-key-pair.p12

Import pkcs12 into JKS

List Keys in JKS
keytool -list -v -keystore keystore.jks

keytool -changealias -alias domain -destalias newdomain -keystore keystore.jks

List pkcs12
keytool -v -list -storetype pkcs12 -keystore rsa-2048bit-key-pair.p12

List jceks
keytool -v -list -storetype jceks -keystore keystore.jck

Export public key from keystore to pem
keytool -exportcert -rfc -alias rsa-2048 -keystore keystore.jks -file rsa-2048-crt.pem
openssl x509 -in rsa-2048-crt.pem -pubkey -noout > rsa-2048-public-key.pem

Apache James 3.0-RC1 Intallation and Configuration in Jdk 1.6

Download from

Unzip to /oracle/james-server-app-3.0.0-RC1/

Then, you have to copy and rename configurations files from the template files in the conf/ folder
cp indexer-template.xml indexer.xml
cp quota-template.xml quota.xml
cp events-template.xml events.xml
cp managesieveserver-template.xml managesieveserver.xml

Look into the configuration of this repo. it could help:

* This command can help you to find details of an compiled class
javap -verbose -classpath /oracle/james-server-app-3.0.0-RC1/lib/joda-time-2.9.4.jar org.joda.time.base.BaseDateTime

  • This command can help you to find a class file in a folder of jar files:
    grep BaseDateTime.class ../lib/.jar (only works in dir containing jar files)
    find ../lib/ -type f -name ‘
    .jar’ -print0 | xargs -0 -I ‘{}’ sh -c ‘jar tf {} | grep Hello.class && echo {}’

  • This command can help you to find the the xml file that contains that word.
    grep -R –include=”.xml” “admin” /oracle/james-server-app-3.0.0-RC1
    or this grep -r -R –include=”
    .xml” -F “8280” /opt/wso2/ei

You have to eliminate the package joda-time in the jar elasticsearch-2.2.1.jar inside the conf folder. Because is compiled in java 7 version.

You have to eliminate the jar files lucene-analyzers-common-5.4.1.jar and lucene-backward-codecs-5.4.1.jar from the conf folder.

You have to execute the james server like this:
sudo /oracle/james-server-app-3.0.0-RC1/bin/james start

You can follow the status of the james server:
sudo /oracle/james-server-app-3.0.0-RC1/bin/james status

You can see the log file of the james server:
cat /oracle/james-server-app-3.0.0-RC1/log/james-server.log

You can add domain like this:
sudo /oracle/james-server-app-3.0.0-RC1/bin/ -h localhost adddomain
