Corrupt OGG starts to import then quits instead of reporting sequence number gap

[OurToaster]

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.

The bug was initial reported in Launchpad [1] and confirmed by me. Here's the
description from the reporter:

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.

oggenc.exe reports:

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.
