[Mac] Hang/infinite loop on loading any OGG file

Hello, I've been using OgreOggSound for a few weeks now, and everything was going fine while testing my application on Windows and Linux. However, once I got to getting it running on Mac, I'm getting a complete dead hang the moment I try to load any OGG file. Loading WAV files works just fine, so I figured the problem is with my Ogg and Vorbis frameworks, however, I re-built them 3 times to no avail really, nothing changed, I just get a hang.

What's strange is that the flow seems to get stuck in an infinite loop, at least that's the impression I got from debugging the app. I will paste the relevant call stack trace below, maybe it makes sense to you (i never worked with OpenAL before, so I'm rather clueless here)



#0	0xffff0657 in __bzero

#1	0x90fb0697 in std::basic_filebuf<char, std::char_traits<char> >::_M_seek

#2	0x90fb46c6 in std::basic_filebuf<char, std::char_traits<char> >::seekoff

#15	0x015ee9cd in OgreOggSound::OgreOggSoundManager::createSound

#16	0x00065f6b in Pixy::SfxEngine::setupGame at SfxEngine.cpp:80

As I said, there's no crash. I can keep stepping forever in that seek call. Here's a dump of OgreOggSound's log:

For the sake of completion, I built the plugin against libogg1.2.2, libvorbis 1.3.2 (from vorbis.com), and Mac OS X 10.6.7's OpenAL framework using my own custom Makefile. If it might be a problem with my OOS build (which I doubt as it seems to be working with non-OGG files), then you can take a look at the Makefile, it's attached to the post.

Edit: can't attach the Makefile, I'll post it here.

#

# Generic Makefile for C/C++ Program

#

# License: GPL (General Public License)

# Author:  whyglinux <whyglinux AT gmail DOT com>

# Date:    2006/03/04 (version 0.1)

#          2007/03/24 (version 0.2)

#          2007/04/09 (version 0.3)

#          2007/06/26 (version 0.4)

#          2008/04/05 (version 0.5)

#

# Description:

# ------------

# This is an easily customizable makefile template. The purpose is to

# provide an instant building environment for C/C++ programs.

#

# It searches all the C/C++ source files in the specified directories,

# makes dependencies, compiles and links to form an executable.

#

# Besides its default ability to build C/C++ programs which use only

# standard C/C++ libraries, you can customize the Makefile to build

# those using other libraries. Once done, without any changes you can

# then build programs using the same or less libraries, even if source

# files are renamed, added or removed. Therefore, it is particularly

# convenient to use it to build codes for experimental or study use.

#

# GNU make is expected to use the Makefile. Other versions of makes

# may or may not work.

#

# Usage:

# ------

# 1. Copy the Makefile to your program directory.

# 2. Customize in the "Customizable Section" only if necessary:

#    * to use non-standard C/C++ libraries, set pre-processor or compiler

#      options to <MY_CFLAGS> and linker ones to <MY_LIBS>

#      (See Makefile.gtk+-2.0 for an example)

#    * to search sources in more directories, set to <SRCDIRS>

#    * to specify your favorite program name, set to <PROGRAM>

# 3. Type make to start building your program.

#

# Make Target:

# ------------

# The Makefile provides the following targets to make:

#   $ make           compile and link

#   $ make NODEP=yes compile and link without generating dependencies

#   $ make objs      compile only (no linking)

#   $ make tags      create tags for Emacs editor

#   $ make ctags     create ctags for VI editor

#   $ make clean     clean objects and the executable file

#   $ make distclean clean objects, the executable and dependencies

#   $ make help      get the usage of the makefile

Any idea?

Cheers guys,

Hmmm, no idea what the problem is here

You could try setting the seek callback to NULL in the OgreOggISound constructor..
mOggCallbacks.seek_func = NULL;

amireh

Thanks, I will try that tonight, and I'm also going to test it on another machine, maybe there's something wrong with my frameworks..

I'll update this post once I have more findings.

Okay,

unfortunately I have neither a MAC myself or access to one or knowledge of its environment to be of much help, I believe someone else has got OgreOggSound running on a MAC before so hopefully they will pick up this thread and offer some advice! :wink:

Hi sticky,

Unfortunately, I didn't get to make it work, I tried setting the flag in OgreOggISound, mSeekable, to false in the constructor and mOggCallbacks.seek_func = 0, but then it crashes (segfault) whenever you set the stream flag to true, and if you set it to false, it won't crash but won't play any sound

I have rebuilt all the frameworks as static libraries instead, but that didn't help either. My choices currently are: drop the music in my game for Mac, or convert my music to WAV which seems to work. I don't like either option >.<

BTW, tracing the crash on scenario #1 with streaming set to true, mSeekable = false, and seek_func = NULL, the segfault happens in the ov_read() part of this line: (OggStaticSound.cpp:106)

sizeRead = ov_read(&mOggStream, data, static_cast<int>(mBufferSize), 0, 2, 1, &bitStream);

malloc: *** error for object 0xf9a1f94f: pointer being freed was not allocated

On another note, is it possible to play MP3s somehow? Rather do it with OpenAL since i'm already linking it.. thinking of the game without music is just lame
