[Audiere-users] Ogg and memory files

[Tim]

First of all, thanks for a good project. It
allowed me to easily make use of OGG in a time
critical application.

------

A question regarding playing OGG files.

I am trying to play a file from a memory buffer,
part of a larger file within memory. I am able
to play these when they are physically on disk,
just not as a memory object.

Here is the snippet all variables are members
of my class so stay in scope and I have checked
that the address/length of the memory buffer is
correct.

The same Ogg device I am using is fine, it works
when I use it to play streams from disk.


class datamembers
-----------------
FilePtr m_oggfp;
bool m_StartupThemeOggLoaded;
OutputStreamPtr m_StartupThemeOggStream;

code snippet
------------
m_oggfp = CreateMemoryFile(buffptr, bufflen);
m_StartupThemeOggStream =
OpenSound(*m_OGGPlayer, m_oggfp, false);

if (m_StartupThemeOggStream)
{
m_StartupThemeOggStream->setRepeat(true);
m_StartupThemeOggStream->play();
m_StartupThemeOggLoaded = true;
}

Hope you can help out.

Tim

Tim,

I remember having similar problems when using the Audiere file format
auto detection. When I explicitly told Audiere to open this file from
memory as an OGG, it worked for me.
Maybe you should give that a try.

Regards,
Matt

Matt,

Yes I did some more searching of old email and finally ran
across that item. You are right of course, as soon as I
identified it as FF_OGG things worked.

As an aside, is there going to be another release, or is
the baseline stable/extensable enough now?

Thanks

It's odd that you have to specify the extension to make it work... Audiere
really needs unit tests. >_> (I hear Ben cheering in the background.)

When I get the build system rewritten in SCons, it should be ready for a
release. The version in CVS is basically what will be released, unless bugs are
found until then. (The fundamental problem here is that I don't have VC6 on my
computer anymore. Thus, I can't use the old method of making a release. So
instead, I'm just making an SCons build to replace all of the others.)
