irrklang playing sound from archive?

Well, im using rar files for media, can irrklang load and play sound from such archive? How?

i guess you mean ZIP file. haven't seen RAR archive support anywhere yet. would be nonsense anyway, since it hinders random access...

Ok, zip. How?

Like loki1985 said.

You would have to use Zlib and extract it to a temp dir, or your may run in to a lot of problems.

If you need it compressed use mp3. Why do you need it in a zip? Keep the audio out side the zip.

Well... games like CALLOF DUTY store sound files COMPRESSED in pk3? if i remember, but pk3 is a zip extension, so i ask is it possible in irrlicht?

Call of duty every time when launched extract sound files to temp dir?

like I said..

in other words. You have to extract them to a temp dir first, like Call of duty does, or ( the alternative ) will result in problems.

Does Irrlicht have built in zip exporting support?, well I'm not sure but it does open a zip, so its possible.

So I guess your question now is. "Can I extract a zip file to a temp directory?" May need to start a new topic as this heading is now misleading

However I dont think its a very on common question. Zlib could handle this. Irrlicht does not limit you to its SDK you can use other libs you know.

well, temp directory might not be needed, but extracting to RAM is (or, to be superkinky, streaming extraction might work too in some cases like BGM).

but as for irrklang, you have to find out how that works. i just seem to remember it was somehow possible to pass file handles to irrklang, virtual ones too.

Did you ever try to zip a mp3 file?
I just did

You can probalby save a few kilobytes by doing so.

To give you an example:
5226299 bytes before compression
5213434 bytes after compression

this makes a difference of
12865 bytes or 12.5 kilobytes or 0,2%

There's no need to unzip, irrKlang can use Irrlicht's virtual file system.

Hi there... I'm just trying to do the same thing, but without any visible, or either audible result.

I'm discussing a possible workaround with CuteAlien in an another forum topic:
