Description Jonathan Marten 2010-11-16 12:10:34 UTC

Version:           2.0-SVN (using Devel) 
OS:                Linux

When creating an audio CD from a series WAV files, the burning process aborts after the "Decoding audio track 1 of ..." stage.  This happens whether burning a real CD or just creating an image.

The burning progress window shows:

Creating image files in /tmp/kde-jjm/
Error while decoding track 1.
Error while decoding audio tracks.
Removing temporary files.

The debugging output shows nothing useful.  k3b's stderr output when this happens is:

k3b(25140) K3b::JobProgressDialog::slotNewTask: "Preparing data"
k3b(25140) K3b::JobProgressDialog::slotNewTask: "Creating image files"
QIODevice::seek: The device is not open
k3b(25140) K3b::AudioDecoder::seek: (K3b::AudioDecoder) seek from  "00:00:00"  (

k3b(25140) K3b::JobProgressDialog::slotNewSubTask: "Decoding audio track 1 of 5"
k3b(25140) K3b::AudioDecoder::decode: (K3b::AudioDecoder) track length:  8206128
 ; decoded module data:  8205488 ; we need to pad  640  bytes.
k3b(25140) K3b::AudioDecoder::decode: (K3b::AudioDecoder) padded  640  bytes.
k3b(25140) K3b::AudioImager::run: (K3b::AudioImager::WorkThread) read error on t
rack  1  at pos  "00:46:39"
k3b(25140) K3b::JobProgressDialog::slotFinished: received finished signal!


Reproducible: Always

Steps to Reproduce:
Prepare an audio CD project with one or more WAV files.

When burning, select "Create image" and "Only create image" to avoid creatin a coaster.  The same happens, though, if burning for real.


Actual Results:  
Burn failure and error messages as above.



Classifying as "major" not because it causes data loss, but because main functionality fails to work.


K3B debugging output, for what it's worth:

Patch to fix

In K3b::AudioImager::run(), from libk3b/projects/audiocd/k3baudioimager.cpp:

        //
        // Read data from the track
        //
        while( (read = trackReader.read( buffer, sizeof(buffer) )) > 0 ) {
.
.
.
        }

        if( read < 0 ) {
            emit infoMessage( i18n("Error while decoding track %1.", track->trackNumber()), K3b::Job::MessageError );

The trackReader.read() returns -1 at the end of the track.  This is not an error, but merely indicates EOF.

The attached patch appears to fix the problem, and correctly creates an audio CD or image.

Comment 2 Mike 2010-11-26 23:39:46 UTC

I had the same occur today after using k3b many times successfully.  It is my preferred burner app on any platform.

The two error messages listed as the burn progressed in the main progress window were

Track 1 error while decoding audio track
Error while decoding audio tracks

After a while the CD was ejected by the app

I then was able to successfully burn the same audio WAV files using Nero Essentials in Win7.

Comment 3 Mike 2010-11-27 20:27:25 UTC

Same error occurred on different PC today.  

(I see there is a patch to fix, but don't think (?) that's for the average user, but for a new release of k3b?  If it's for the user to install, I'd be glad to receive instructions on how to do it.)

Trying to burn different WAV files, converted from mp3 with Audacity, audio book files with tag data on different PC today.

After k3b error, I was then able to burn fine with Nero Essentials on Win7.

Exact error message in k3b gui:

"Error while decoding track 1"
"Error while decoding audio tracks"
