Export audio from video file

January 17, 2008 · Posted in Linux · Comment

There are some times that all of us had a live consert of a band on .avi format and we ‘d like to export a song from that

here is the way to to that

1) mplayer -dumpaudio AVI_FILE_NAME.avi -dumpfile MP3_FILE_NAME.mp3

Now we have the whole audio data from our video on MP3_FILE_NAME.mp3

Now using mp3splt we can isolate only the part we want like this

2)mp3splt MP3_FILE_NAME 10.23 11.24

10.23 =minutes.seconds

If the part we want to cut stars on 1:25:12 we well write is as : 85:12

Now a new file with the name MP3_FILE_NAME_1030_11_24.mp3 created with the audio part we wanted

I must say that 0.24 version was released on February 2007 !!!! . Anyway I did the ebuild for Argouml-0.24 and I am giving it to you

Assertion `c->xlib.lock’

January 8, 2008 · Posted in Gentoo · 2 Comments

I had several problems with this Java Bug . Finally I found the solution so im gonna write it down ( For Gentoo Users )

1) Emerge x11-libs/libxcb-1.1

Check out the final message after the emerge
* libxcb-1.1 adds the LIBXCB_ALLOW_SLOPPY_LOCK variable to allow
* broken applications to keep running instead of being aborted.
* Set this variable if you need to use broken packages such as Java
* (for example, add LIBXCB_ALLOW_SLOPPY_LOCK=1 to /etc/env.d/00local
* and run env-update).

That solved my problems for most of java programs that couldnt start at all
