Bug Description

I can not open a certain ogg file with audacity. When I try to open the file it displays the import dialog but closes it after some progress. Same happens if I try to import it. It does not show me any error message. The file plays fine with any audio player i tried so far. I can also open different ogg files with audacity.

The file was recorded with gnome-sound-recorder (ubuntu default) in the ogg-format.

I tried with audacity 2.0 and Audacity 2.0.3-alpha-Oct 7 2012. Same result.

The file is 72 MB at about 80 min.
Information about the file
Vorbis Audio
Stereo, 44100Hz, 160kb/s

I can also provide the file if neccessary. I opened a new bug for this. I'm quite new to opensource community, so please let me know if that wasn't correct and if I can provide further information.

I use ubuntu 12.04, kernel 3.2.0-31-generic on 64bit

Thanks for help!

The problem is not the system, but the size of the file. I would suggest uploading parts at a time, then "glue" back in place.

I tried now to split the oggfile in several parts using oggCut from oggvideotools. Whenever I try to open one of the splits in audacity, it opens perfectly. Maybe the file was just corrupt somehow.
I received folling message when I split it with oggCut:
user@host:~/Music$ oggCut -s 825000 -e 4680000 H.ogg H_Part1.ogg
Stream No: 0(0x3d051edb)
Vorbis Stream:
 with 2 channels
 and 44100 kHz sample rate
 and 160000 data rate

StreamMux::operator<<: Warning: packet number for stream <0> not matching: expected: 3 got 65537

It would be nice if audacity would print a message saying the file is corrupt. I'll try to upload whole uncut the file now.
My problem is solved. Thanks.

Audacity should show an error message instead of silently fail when opening a corrupted ogg file.

I can confirm the opening failure with your provided test file.

IMPORTANCE changed to P5, Repeatable.

Confirmed on Windows 7 but the file is corrupt.

oggdec.exe crashes trying to play it, hence probably why the import aborts.

I suggest user installs FFmpeg, then in Audacity does File > Open or File >
Import, and selects the "FFmpeg-compatible files" filter. The file will then
import using FFmpeg providing user has not unchecked "Attempt to use filter in
OpenFile dialog first" in Extended Import Preferences.

I downloaded the ogg test file from the link provided in Benjamin's comment #0

Testing on W10 with audacity-2.3.3-alpha-252-88dc11f525215cea57f7a89b0038fc7d40a50149

This formerly problematic ogg file I can now import properly into Audacity with drag&drop and File>Import. I can also File>Open the test ogg file.

So there no longer appears to be a problem on Windows with is particular ogg file.

This should also be tested on Linux before closing this old bug

On Linux, the file https://bugs.launchpad.net/ubuntu/+source/audacity/+bug/1063298/+attachment/3383394/+files/H.ogg imports correctly, and error messages are correctly logged in the Audacity log (as shown below).
Closing this bug as fixed.
