ZDoom with OpenAL

[morbidtwatt]

I'm playing zdoom on bsd with the openal patch that Chris created. By the way chris you are the man. Zdoom sounds incredible with openal because I can hear an audible difference. With the openal patch I can hear things get closer to me or farther away. There is this audible feeling of distance between me and the monsters which really makes me feel like I am in the doom world. For example I can walk closer and hear them get louder because the audio fades in. The openal I assume is the cause of this effect of fading in and out, but im not sure. The other day i moved up from zdoom 2.2.0 to 2.31 all thanks to Chris (I love you). Maybe this is an effect that was in one the past versions after 2.2.0. Anyways, I love the outcome of zdoom's new audible depth. I would love to see future wads use the real time fx aswell because it gives great ambiance to the levels.

Updated to r1623. This handles underwater reverb, and it will also use the EAX-style reverb effect if available, falling back to standard reverb if not. Hardware-backed OpenAL can potentially use EAX reverb, and Creative's software driver also exposes EAX reverb (although not all of the reverb properties are supported; basically anything that's not part of the standard reverb doesn't seem to have a noticeable effect). The GIT version of OpenAL Soft can also handle EAX reverb, and it will use the HFReference and panning vector properties.. more properties will be supported in due time.

I compiled zdoom with this patch on linux but get this error when runnning zdoom:

I_InitSound: Initializing OpenAL
H Driver 0 does not exist. Using default.
G Could not open device: Context creation failed
GSound init failed. Using nosound.
Could not create music stream.
If your soundcard cannot play more than one
wave at a time, you will hear no music.

I tried several snd_driver # but none of them work.

note: openAL works in vavoom.

EDIT: nevermind my version of openal was outdated.
But now it crashed zdoom after a few minutes.

Update to r1771. Nothing really new on this side, other than the patch applying again, but the GIT version of OpenAL Soft now supports 32-bit float output, and setting snd_samplerate can now have an affect due to the ALC_FREQUENCY context attribute doing something.

EDIT: nevermind my version of openal was outdated.
But now it crashed zdoom after a few minutes.

Is it crashing in openal or oalsound.cpp? Can you provide a backtrace?

I've tried to upgrade it to work work with revision 1991, and I fixed the collisions in CMakeLists.txt and i_sound.cpp. It compiles fine without OpenAL, but with OpenAL it fails because there's a few functions that were added for Fmod that OpenAL doesn't have:

Big update.

This version drops Alure (it's taking too long to get the next version ready), instead opting to use GStreamer for both music and sound decoding. This basically means any format supported by GStreamer will be available to the game. Ideally GStreamer would have this plugin, but it will work without it. All the GStreamer code is kept in the OpenALSoundStream and Decoder classes, which also operate independently of each other, so they can be ifdef'd for different OSs (eg. DShow/ACM in Windows, QuickTime on OSX).

GStreamer 0.10.23 or newer is currently required for OpenAL support, which should not be a big deal on Linux. With GCC, the functions are marked as weak symbols, so even if the headers are present, linking will not fail if the libs are unavailable (but run-time won't be able to use it, even if DLLs are provided). I don't know if MSVC has a similar ablility.

General improvements in the backend itself include properly saving/restoring the sfx offsets from savegames, a name-based device selection cvar/option, device disconnection detection when ALC_EXT_disconnect is supported (eg. if a USB headset gets uplugged, or PulseAudio dies, it will theoretically detect it and restart sound on another device automatically), the DecodeSample method is implemented (for Vorbis-encoded instruments in module files; thanks to GStreamer), and various other tweaks.

EDIT:
Minor update to fix a buffer leak

I'm still playing around with this, but so far it's been acting a bit weird on my system. When ZDoom starts the sound is initially not working correctly, it crackles and does other weird stuff. After a little bit it's fine again. PulseAudio has been giving me some issues, so it could be that. However, I do have 2 questions.

What does this mean?

I get it if I simply start ZDoom, wait for the sound to fix itself, and then quit.

This message flooded the console after I started a new game.

Edit: the oalsound.cpp:351 goes away if I play with -nomusic.

And now it segfaulted.

Edit 2:
Something really bizarre is going on here. I have both the OpenAL and FMOD dev packages installed on my system, so ZDoom has compiled with support for both, yet even though OpenAL has been selected as my sound source, the segfault occurs in fmodex.

Possibly, especially if you're on an older OpenAL Soft. Using the ALSA backend (with mmap disabled) may work better, but PulseAudio does make things difficult.

That means it couldn't create an openalsink for music playback, either because you don't have the plugin, or have an older OpenAL. With that, it'll just fall back to using the (sub-optimal) appsink to play with.

That's odd. It's failing to unqueue the buffers it reports as processed. What version of OpenAL do you have?

Do you have a longer backtrace? I've had issues before with FMOD hijacking functions, because it doesn't use visibility to hide what's not part of its defined ABI.

[Siggi]

What version of OpenAL do you have?

I believe it's 1.8.466.
Wikipedia tells me the latest is 2.1.0.0, so I guess I do have an older version. You can blame Ubuntu for that.

Well that's the funny thing; that's supposed to be from a debug build being run through gdb.

Here's all the gdb output:

If there's something I can do to make ZDoom or gdb more informative, let me know.

[Chris]

What version of OpenAL do you have?

I believe it's 1.8.466.
Wikipedia tells me the latest is 2.1.0.0, so I guess I do have an older version. You can blame Ubuntu for that.

The latest Linux version is actually 1.12. The 2.1 might be Creative's hardware driver version, though I"m otherwise not sure where the number comes from (the spec is at version 1.1, and Creative's software driver for Windows is 2.2.0.7).

EDIT
And yes, btw, it seems it's a bug in that version to cause it to report processed buffers that aren't there to be unqueued, under certain situations. It's been fixed in newer versions.
/EDIT

Well that's the funny thing; that's supposed to be from a debug build being run through gdb.

I got it built with OpenAL and FMOD, and was able to get a more informative backtrace. And it's indeed what I feared:

        flacdec = 0x99c9ff0
        s = <value optimized out>
        is = <value optimized out>
        __FUNCTION__ = "gst_flac_dec_loop"

FMOD has its own built-in/modified copy of libFLAC, so when GStreamer's FLAC plugin tries to call functions from the real libFLAC, it ends up calling FMOD's functions since they were there first. The plugin-based lib (libfmodexp) seems to avoid the issue, since dlopen'd libs don't have their function symbols added to the global symbol table by default, but that would require having the plugins sit next to the executable to be useable.

[Siggi]

I got this to work happily on a fresh install of Ubuntu 10.04rc 32bit. This time I made sure not to install fmodex.

Cool. Not exactly sure where those messages are coming from, since it's before PulseAudio/ALSA are loaded or GStreamer is initialized, unless GStreamer does some constructor stuff that triggers it. It's related to BlueTooth audio, and the only time I see it is when it starts to play an MP3. It's harmless, though.

How in the heck do you get this thing to compile? Using OpenAL Soft, GStreamer WinBuilds SDK v0.10.6, and Visual Studio 2008.
