Audio / Re: Loading certain ogg files in SFML 2.4.2 causes program to hang forever.

Ok, I'll try stepping through this to see why the Flac decoder is getting hung up and see if there's something I can do with my InputStream to ensure that its correctly identified as Vorbis. Thanks for the help!

Thanks for taking a look at this!

I can't confirm this. It plays fine when I open it with sf::Music directly (using MinGW).

Well its failing using sf::Music openFromFile (everything related to streams and anything else having to do with the file nixed right out) on the 32bit version of Visual Studio 2015, using the version downloaded from the SFML page in Windows 10, with the libs/includes/dlls all set up pretty standard, nothing fancy or custom.

Quickly firing up the debugger and stepping through the SFML code, it seems like the OGG file is for some reason throwing off the FLAC decoder.

Why would it throw off the FLAC decoder when my file is encoded via vorbis?

$ oggz codecs hangs_forever.ogg
> vorbis

The way SFML has implemented the audio format detection is that it would pass it to the various decoder libraries and let them judge whether it's a format they can read.

Is there an easy way I can override this and force it to use vorbis?

Audio / Loading certain ogg files in SFML 2.4.2 causes program to hang forever.

Hello,

I am updating an application that uses sfml-audio from 2.1 to 2.4.2 that consistently hangs forever when loading certain ogg files. These files did not hang in 2.1, and it is only specific files that cause this.

Here is a link to one of the ogg files that causes our program to hang: https://www.dropbox.com/s/1gxh56ym6kk2nla/hangs_forever.ogg?dl=0

Here is a link to a minimal example showing the error, assuming the above ogg file is downloaded into the working directory: https://gist.github.com/jamiltron/ada86682674717ab0bd9e0f2f90343dc

The above fails if you remove the stream and change the .openFromStream(stream) to .openFromFile("hangs_forever.ogg"). This file plays fine in every media player I've tried, and also loads and plays using another client solution.

This happens on Windows 10 with both the 32-bit Visual Studio 2015 prebuilt, as well as a version built from source containing the following patch to libvorbis: https://trac.xiph.org/ticket/2327

Any help is greatly appreciated!
