How to play MP3,WAV,OGG,FLAC,MP4,M4A ?

[Bong.Da.City]

Same problem here... I finally managed tto install phonon and compile the application... Thanks to hakermania.. Anyway it doesn't play mp3 files.. I also have those packets you mentioned before....

gstreamer0.10-ffmpeg
gstreamer0.10-fluendo-mp3
gstreamer0.10-plugins-ugly

Can you play those mp3 files using pure gstreamer? Please also note that Phonon requires particular version of gstreamer (as mentioned in the docs).

[hakermania]

Yeah. I can listen to mp3 files through pure gstremer. So, Phonon has a lot of dependencies as I understood. This means that it is not so useful because users that will use my app would have to download and install all these packages in order to Phonon to work, right?... How about using QAudioOutput? What does it support?

[wysota]

If you install phonon, your package manager should install all dependencies as well. Actually I'm using xine backend for phonon on my Linux box and not gstreamer. I only had to install phonon-gstreamer and phonon-xine packages for both backends.

[hakermania]

Thanks, but my package manager cannot find the files you specified. Also, what about QAudioOutput ? Can I play music with this?

[hakermania]

I found a code and tranformed it (hehe) to this:

#include <QFile>
#include <QAudioFormat>
#include <QAudioOutput>
#include <QSound>
 
int main()
{
  QFile inputFile;
  inputFile.setFileName("/home/alex/Music/noh.wav");
  inputFile.open(QIODevice::ReadOnly);
 
  QAudioFormat format;
  format.setFrequency(8000);
  format.setChannels(1);
  format.setSampleSize(8);
  format.setCodec("audio/pcm");
  format.setByteOrder(QAudioFormat::LittleEndian);
  format.setSampleType(QAudioFormat::UnSignedInt);
  QAudioOutput *audio = new QAudioOutput( format, 0);
  audio->start(&inputFile);
  return 0;
}

#include <QFile>
#include <QAudioFormat>
#include <QAudioOutput>
#include <QSound>

int main()
{
  QFile inputFile;
  inputFile.setFileName("/home/alex/Music/noh.wav");
  inputFile.open(QIODevice::ReadOnly);

  QAudioFormat format;
  format.setFrequency(8000);
  format.setChannels(1);
  format.setSampleSize(8);
  format.setCodec("audio/pcm");
  format.setByteOrder(QAudioFormat::LittleEndian);
  format.setSampleType(QAudioFormat::UnSignedInt);
  QAudioOutput *audio = new QAudioOutput( format, 0);
  audio->start(&inputFile);
  return 0;
}

but the only output is
QObject::startTimer: QTimer can only be used with threads started with QThread and no sound is heard.. (--_--)

Well, obviously this won't work, especially if you exit the application immediately. Query your package manager for phonon and install everything related to it. You should at least get playback for the free formats (like ogg). Test it with the mediaplayer Qt example.

[hakermania]

Thank you. I installed Phonon and I tried the MediaPlayer example. unfortunately, even after the installation of all the codecs I can't still play mp3 files. This is quite embarrassing because there are some apps that support mp3 file playing, like Alarm Clock from the Software package manager in ubuntu... I downloaded the source but I didn't understand how does it do it haha.... anyway.... Is there any other other way to play mp3 files?

Can you play ogg files? Or any other kinds of files?

[hakermania]

Yes. i can play ogg and wav files. But I cannot play mp3 at all. All mp3 codecs need have been installed. We spoke about phonon and codecs that should be installed in this thread at post No#10 - post No#18
So, as Bong.Da.City has the same problem with me, I don't believe that there is a problem with the system codecs, as the necessary codecs have been installed. :/
If there is no solution on how to play mp3 files with phonon, I would like at least to know how to make the code that I posted above work and I'll use canberra-gtk-play (see post No#1 in this thread) as it supports wav and ogg files as well, so there is no point using phonon libraries as i have already include stdlib.h and i can call system() to play the sound....

[wysota]

Apparently not.

Run the phonon/capabilities example and see the list of supported file types.

Bearing the fact that canberra-gtk-play probably uses gstreamer, the same as phonon that uses gstreamer, I don't really see the point of doing that. Phonon has nothing to do with the fact whether you can or cannot play mp3 files. If you can play anything then phonon works fine. Its work ends with passing the stream of bytes to gstreamer. By the way, you can also try the xine phonon backend from kde, maybe it'll work better for you. Also check if you can play the mp3 with totem as it has gstreamer as its backend too.

I can play mp3 files with totem:
