Ogg vorbis crash

Question

I'm trying to add support for Ogg Vorbis in my project (C++, VS 2010). I had no problem compiling LibOgg + LibVorbis to produce a static library.

My procedure is this:

LibOgg

• Download LibOgg
• Build LibOgg with dynamic solution (Release)
• Get a libogg.lib export and a libogg.dll in /Release folder

LibVorbis

• Download LibVorbis
• Set appropriate include + library folders for LibOgg
• Build LibVorbis with dynamic solution (Release)
• Get a libvorbis.lib and libvorbisfile.lib exports and libvorbis.dll and libvorbisfile.dll in /Release folder

My program

• Set appropriate include + library folders for Libogg + LibVorbis .lib exports
• Place .dll in working directory

The build succeeds but unlike the static build (which works), the dynamic build just crashes in the first ov_open call (which opens some .ogg file). I built lots of libraries (GLEW, SQlite, etc.) yet this one gives me the nuts.

Answer 1

Never mind, i solve this. It seems OggVorbis is touchy when it comes to Windows and use of ov_open due to some linking issues with stdio.h and fopen.

Documentation says it clearly:

WARNING for Windows developers: Do not use ov_open() in Windows applications; Windows linking places restrictions on passing FILE * handles successfully, and ov_open() runs afoul of these restrictions [a]. See the ov_open_callbacks() page for details on using ov_open_callbacks() instead.

Although it is recommended by docs to use callbacks, i found ov_fopen to be reliable which works for both static and dynamic builds with the OggVorbis; the dynamic build will crash your program if you use ov_open on Windows.

Going to update this answer after i test it against Linux and OSX to verify ov_fopen as a safe, all around solution.

UPDATE

As said, i tested the use of ov_fopen on Windows 7, Linux (Lubuntu), OSX (10.8.2) and Android (KitKat 4.4.4) and i found out that works reliably. So, for those allergic to callbacks (like me), ov_fopen proved reliably.
