Ogg Vorbis and WAV streaming support
by Kurtis Seebaldt · in Torque Game Engine · 04/16/2002 (9:31 pm) · 51 replies
I've finished up my Ogg Vorbis and WAV streaming support. I've added one new field to the AudioDescription datablock 'isStreaming'. Set it to true and then create an AudioProfile using the streaming description and a WAV or Ogg Vorbis file and go. It supports looping by setting 'isLooping' in AudioDescription.
It is theoretically cross-platform, but I've only updated the VC6 project files. I'm not to good with Makefiles so I haven't tested Linux support, and I don't have a Mac to test either. It only uses the Ogg Vorbis library, OpenAL and the Torque Resource Manager so it should be ok.
This one uses the Ogg Vorbis SDK files instead of full source):

Btw, anybody else tried to integrate this?

Sorry guys, I just noticed I had the ogg and vorbis include and lib paths on my global VC directory list. Let me fix up the project files and replace the broken zip.

I'm thinking it may be simpler to just include prebuilt Ogg Vorbis LIBs and DLLs instead of rebuilding them every time. When I get home tonight I'll look into it. Should shrink the size of the zip too.

This zip is only 200k vs 1.2M for the other one.
Stefan:
the "vorbis/codec.h" should be in lib/oggvorbis/include in this zip. Set up your project to use that directory in its incliude path.

I've made a new version that no longer includes all the Ogg Vorbis source. It just uses the SDK files (LIBs, DLLs, and includes) www.flamultimedia.com/audioStreaming2.zip

Have you submitted this as a resource yet?

Cool, that should be much easier to deal with.Have you submitted this as a resource yet?

anyhow, there seem to be some more updated files missing, because I still get the following errors:
Maybe I need the latest head to get it right?
Mine is about 4 weeks old now...
EDIT: Yep, seems to be a HEAD issue, try to figure it out... nevermind!

Sorry, the missing header was my fault... should have thought of including the directory...anyhow, there seem to be some more updated files missing, because I still get the following errors:

All my stuff is based on the HEAD files from about a week ago. I haven't tried it on 1.1.1.

Now, the engine doesn't run super smooth on my machine at the best of times, so perhaps that's what it is. What kind of impact have you been seeing? Is the decoding speed dependent on the level of compression the Ogg has?
04/17/2002 (11:02 am)
I got it in and working.. though I was surprised at the frame rate hit I got with an Ogg. I expected some, but it got as much as 50% slower at times.Now, the engine doesn't run super smooth on my machine at the best of times, so perhaps that's what it is.

still doesn't work for me... now I don't get any compile errors and my exe gets build, but there is no ogg.dll built and so TGE doesn't launch and quits with an error ... anything I'm still missing? Thanks!!

In the audioStreaming2.zip, the dlls are in the example directory.

I haven't done any profiling yet. I've tried to do some rudimentary profiling (use timeGetTime()) but the resolution is to low. I always get 1 millisecond elapsed to load a new buffer from an Ogg Stream. Is there a built in fps counter in Torque?Stefan:

As far as fps is concerned - I still got my normal framerate while playing a 4MB ogg file (126 kbps, 44kHz)... you can check the fps by typing metrics("fps") in the console...
thanks for the great work!!

#16
is it possible to play "normal", like weapon e.t.c sounds in OV format, too? Or is it just meant for backgound music and such? Just curious.... ;-)
Great enhancement to TGE, by the way! No we can get rid of these huge WAV files for music... :-)) Thanks again for providing it!

#17
I've been meaning to test out an AudioEmitter that streams music. That would be cool :)
Another way would be to modify AudioBuffer to decode the entire Ogg Vorbis stream into the buffer. It won't be compressed anymore, but it would allow you to store non-streaming audio in Ogg Vorbis format. I'll have to look into that.
04/17/2002 (3:58 pm)
Technically, you should be able to play normal sounds too. Just set "is3D" to true on the AudioDescription. It will still stream it though. I've been meaning to test out an AudioEmitter that streams music. That would be cool :)

I've been doing some rough profiling using the fps counter and on my machine (Athlon XP 1600+, GeForce4 4400) the Ogg Vorbis Stream adds about .5-1.2 mspf. That equates to 1-2 fps less depending on my max. Not too bad. Adjusting the number of buffers and size of buffers may affect this. Right now its set to 16 buffers of 32k each.

One thing I forgot to mention in my first post - thanks for your great work! This is going to be a big deal once it's fine-tuned.

Well, I've done some more speed testing this time in a Release instead of Debug build. For one, I never drop below 60 fps in Release while I was getting about 33 or so in the middle of the village in the Realm Wars map. Anyway, in the Release build I see practically NO difference in frame rate. So Simon, could you give me some numbers on how the Ogg stream affects your frame rate?

So obviously the file 'vorbis/codec.h' is missing and some other strange things are going on...
Any ideas what might be wrong? Thanks in advance!
P.S. Would be great if you could provide some info what to change in the VC project files, cause I added a lot of files to the official GG release, so I can't simply replace them... thanks!
