Burning An Audio CD On Linux Mint

how you can convert your mp3 audio files to a format accepted for burning audio CDs and burning them on a blank CD afterwards on Linux Mint 11.

This tutorial comes without warranty of any kind.
1 Preliminary Note

There are multiple ways and applications to convert and burn your audio files, however the ones I use happened to produce no problems that others did, e.g. inflating the size of the produced .wav file so greatly that a 13-track album would not fit on an ordinary blank CD. If other applications cause you no problems, you can also use those instead.

2 Converting Audio Files To Wav Format

to use for converting is a graphical user interface called WinFF. To install it, open a terminal and enter

sudo apt-get install winff

Enter your password

winff

just drag and drop one or more audio files to the white input panel or add them by using the Add button. Select Audio in the Convert To… dropdown menu and Wav for CD in the Preset dropdown menu. You can also configure the directory the output files will be saved in. After you are done, press the Convert button. The files can then be found in the selected output directory.

Converting Audio Files On Linux Mint

It covers the issue of converting audio files on Linux Mint. Converting audio files can be a hard thing to accomplish if one does not have the proper tools to do so, that is why I will also cover a few different applications capable of converting.
1 Preliminary Note

concentrate on those that are able to convert between the most used formats (mp3 for storing and listening, wav for creating audio disks and some others). Along with the output format, the bitrate might be the most important feature of an audio file. It determines the quality of the sound, so make sure that you do not choose one that is too low (320 kbps is quite a high bitrate and a good choice if you convert music).

2 WinFF
WinFF is a graphical user interface (GUI) for the command line converter ffmpeg, meaning it has the same functions but also is using a user-friendly graphical environment. It is able to convert audio as well as video files into numerous formats used on ordinary computers but also on all kinds of other hardware such as smartphones and multimedial mp3 players. It converts audio files into mp3, wma, wav, ogg and Ac3 format using all bitrates and samplerates

Install

sudo apt-get install winff

After the installation is done, open WinFF by entering

winff

Ripping An MP3 CD On Linux Mint 11

to rip music off an audio CD in acceptable shape with a moderate bitrate and in MP3 format on Linux Mint 11.

1 Preliminary Note

The way I describe should provide all these things, however it may be that if you are ripping a rather unknown audio disk, there is no data about it on the CD database.There are are numerous ways of ripping a CD on Linux, but not all of them provide the standard comfort one should have, for instance a fairly high bitrate for your music, so that it does not sound like hammering on a trashcan with an iron spoon, or automated fetching of disk and track information from the internet, so you do not have to do it all manually.

2 Installing RipOff

to use for ripping is RipOff, you can find it in the standart repositories of Linux Mint. Open the Package Manager and enter your password.

Search for ripoff

need the ripoff-mp3-plugin so mark that as well

3 Extracting an Audio Disk

installation has finished you can find RipOff in Menu > Sound & Video > RipOff. Click once to open it

Integrate Video Streaming Into Your C/C++ Application Using Nex Gen Media Server API

NGMS comes with transcoding support and is able to capture and reformat live video streams and adapt them to be received by another type of device, such as capturing an HD video feed and converting it to be received by an iPhone over 3g. My focus was to integrate the NGMS API to control the streaming features directly from my own C application. In this example I am using Ubuntu Linux 10.04.

Setting up the application

integrate NGMS directly into my C application I had to include ngms/include/ngmslib.h into my code
I had to include the libraries ngms/lib/libngms.so and ngms/lib/libxcode.so. It seems that libngms.so also depends on libcrypto.so, which needs to be specified in the linker options

simple makefile

#Example Makefile


CC=gcc

CFLAGS=-ggdb

INCLUDES+= -I ngms/include

LDFLAGS+= -L ngms/lib -lngms -xlcode -crypto



all: myapp


%.o: %.c

        $(CC) $(CFLAGS) $(INCLUDES) -o $@ -c $<


myapp: myapp.o

        $(CC) -fpic -o myapp myapp.o  $(LDFLAGS)

the source to myapp.c

/**

 *

 * Example myapp application

 *

 */


typedef unsigned int uint32_t;

typedef unsigned long long uint64_t;

#include <stdio.h>

#include "ngmslib.h"



int main(int argc, char *argv[]) {

    NGMSLIB_STREAM_PARAMS_T ngmsConfig;

    NGMS_RC_T returnCode;



    returnCode = ngmslib_open(&ngmsConfig);

    if(NGMS_RC_OK != returnCode) {

      fprintf(stderr, "ngmslib_open failed\n");

      return -1;

    }


    ngmsConfig.inputs[0] = "mediaTestFile.mp4";

    ngmsConfig.output = "rtp://127.0.0.1:5004";


    returnCode = ngmslib_stream(&ngmsConfig);

    if(NGMS_RC_OK != returnCode) {

      fprintf(stderr, "ngmslib_open failed\n");

    }


    ngmslib_close(&ngmsConfig);


    return 0;

}

to open the stream in VLC player and play the video

VLC Player -> Open Network rtp://@:5004

the ngmslib_stream function call is a blocking operation, to interrupt the stream I can call ngmslib_close from another thread and the ngmslib_stream call will exit

ngmsConfig.rtmplive = "1935";

    ngmsConfig.live = "8080";
//ngmsConfig.inputs[0] = "mediaTestFile.mp4";

    ngmsConfig.inputs[0] = "rtp://127.0.0.1:5006";

    ngmsConfig.strfilters[0] = "type=m2t";

Configuring Compiz On Ubuntu 11.10 (Oneiric Ocelot)

I’m using an NVIDIA GeForce 8200 here). With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop
1 Preliminary Note
It should work the same way with all other NVIDIA graphics cards. However dealing with Compiz may cause your graphic drivers to crash, so be careful about what you do and backup everything you might need in future.

2 Installing CompizConfig Settings Manager
Download it by opening a terminal and entering the following

sudo apt-get install compizconfig-settings-manager

The usual thing would be that there’s still no composing working, even if you enable it and all the appropriate options in ccsm.

3 Configuring The Right Driver

sudo nano /etc/modprobe.d/blacklist.conf
