Own speaker implementation #2

dy · 2016-02-10T00:50:54Z

npm install audio-speaker gives

C:\Users\dmitry\Dropbox\Projects\audio-through\node_modules\nan\nan.h(41): fatal error C1189: #error :  This version of
 node/NAN/v8 requires a C++11 compiler [C:\Users\dmitry\Dropbox\Projects\audio-through\node_modules\speaker\build\bindi
ng.vcxproj]

This happens only when local version of node-gyp is used. Probably some config needed or something. Because global node-gyp rebuilds speaker just fine.

The text was updated successfully, but these errors were encountered:

dy · 2016-02-10T00:59:37Z

Or maybe that is a perfect reason to study prebuild. Because it’s annoying to wait for TooTallNate to merge speaker as well as the whole situation with absence of sound in node is a sort of crap - it’s 2016, we’ve sent satellites to Mars.

dy · 2016-05-09T02:46:36Z

speaker also really needs .npmignore.
Guess we need own implementation.

vectrixdevelops · 2016-08-27T00:57:18Z

I can work on this if you'd like? @dfcreative

dy · 2016-08-27T02:14:24Z

Wow, that would be awesome

vectrixdevelops · 2016-08-27T02:41:58Z

I'm just creating a mirror of the mpg123 svn repo to git, so we can easily keep the library up to date, give credit to those who made it and let people modify it through git. Then we can add it here as a submodule and make the binding.

I'm not the best with C++ and C, but we'll put it on a separate branch in case someone else can contribute to it if I can't make it.

dy · 2016-08-27T05:38:15Z

Yeah, that is good to have mpg123 updated automatically. The point as I get it is not C/C++ but node bindings, that takes good knowledge of v8.
Speaking practice, running build on npm install is always a headache for npm users. For example, for now to use node-speaker for windows users we need installing microsoft SDKs, which are 7Gb of extra space, just for tiny module.
I tried to research node prebuild to avoid that, but that was too difficult for me..

vectrixdevelops · 2016-08-27T06:22:26Z

Alright, I will look into prebuild and yeah the bindings will be difficult, but it's worth giving it a shot. For windows building maybe this is a temporary fix https://www.npmjs.com/package/windows-build-tools although I have found it doesn't set the python path very well, although they are working on a fix I believe. It also requires cmd or powershell to run in admin.

vectrixdevelops · 2016-08-27T22:55:40Z

I have got a mirror setup now. I will start working on the binding. https://github.com/connorhartley/mpg123

vectrixdevelops · 2016-08-29T03:06:51Z

Just some information on what I've done. Basically I have forked mpg123-mirror from my profile to audiojs to make modifications specifically for audio-speaker. Currently binding-implementation compiles on Windows fine. I am going to focus on finishing the binding for Windows then we will worry about porting this to other operating systems and arch types. I will need help with testing this on the other systems afterwards.

dy · 2016-08-29T03:16:38Z

Yeah, I am also on windows, cc @jamen

vectrixdevelops · 2016-09-02T23:44:51Z

The C++ binding stuff is done, now all we'll need is the JS implementation for this. I'm open to suggestions on implementation. @dfcreative @jamen @ahdinosaur @mmckegg

dy · 2016-09-03T21:26:33Z

@connorhartley
The branch seems to be an orphan, it has no master’s history. For pull-request we will have to create a new branch I guess.

Also now it’s a bit tricky to figure out how to install mpg123. That would be nice to add that to readme.

Also that is must-have package.json with build script.

Also I do

node-gyp clean;
node-gyp configure;
node-gyp build;

...

Not sure what’s up.

vectrixdevelops · 2016-09-03T22:01:43Z

@dfcreative
Yeah I will rebase before I merge to master.

I will add the readme very soon, along with instructions for configuring mpg123 a long with build instructions.

What version of Visual Studio are you using?

EDIT

The error can be caused by multiple reasons, try the following.

npm install --msvs_version=2015

Alternatively to save time in the future for building, you can set an environment variable.

Variable: GYP_MSVS_VERSION Value: 2015

If that doesn't work, I would take a look at the other options in this SO answer I found.
http://stackoverflow.com/questions/32556295/npm-install-error-the-build-tools-for-v120-platform-toolset-v120-cannot

If that doesn't work, let me know. 😄

Basically config.h is not found, feels like mpg123 needs to be configured or something.

vectrixdevelops · 2016-09-04T01:24:30Z

@dfcreative
Could you paste the whole error (specifically gyps info) as I can't seem to reproduce the error?

EDIT

The latest commit may fix your problem, as the target arch default was ia32 (maybe your arch type is also ia32) and I hadn't made a configuration for it. If you are running x64 use --target-arch=x64 when building and configuring. Note: I will put this information in the readme after.

dy · 2016-09-05T21:20:29Z

@connorhartley btw considering the latest changes in @audiojs, for own implementation it would be enough to have write(buffer, cb) function, not necessary to implement stream wrapper

vectrixdevelops · 2016-09-09T02:27:25Z

@dfcreative did that error get fixed?

dy · 2016-09-09T03:29:49Z

Naah, still get the same error - config.h not found. I just copied the code of audiojs/mpg123 into src/mpg123 folder, I guess it has to be configured or something... When I tried to do the same thing before with updated mpg123 I got the same error and just gave up

vectrixdevelops · 2016-09-09T03:38:23Z

@dfcreative have you tried setting the --target-arch flag in the build and configure command?

e.g
node-gyp configure --target-arch=x64
node-gyp build --target-arch=x64

If the problem persists please let me know. 😄

@dy I would like to get up to speed with this and I thought if somebody could share their build script for npm run build, that would be great. As I understand it the config.h error happens after trying to reconfigure node-gyp. I would like to understand better if anybody else other than @dy has been able to reproduce the config.h. I would like to really understand deeply how each library component works and why you guys need/want it. Not in terms of audio capabilities level (as of yet) but just on a 'build' level for now. Another question I have potentially, does napi allow to switch versions without recompiling/rebuilding just to avoid the nan problem as seen on this issue? Is using napi with mpg123 instead of nan viable? Because if there's a missing win32 identifier problem (as the error states) maybe there's a wrong abi (configured for 64bit) and some value is not being read. I might be talking nonsense but I just want to gauge the surface and learn more. What are your thoughts? One thing is for sure, implementing a new cubeb cross-platform with napi will be somewhat groundbreaking. I think of all those native speed low latency audio streaming possibilities. Or maybe the new features you're after for the speaker output are different. First thing is first though. Once I cover all possibilities that may cause the error as it pertains to the gyp mgpg123 binding and the configure command, I'll move onto other things.

I guess there's no abi in nan.

dy · 2019-03-06T02:09:34Z

@Elemino I didn't work much with low-level API, I was mostly concerned with consistent modules interface and optimal js code. That question is better addressed to @jamen or @connorhartley, the guys spend more time on that (thanks for that!)

jamen · 2019-03-06T05:23:36Z

As I understand it the config.h error happens after trying to reconfigure node-gyp. I would like to understand better if anybody else other than @dy has been able to reproduce the config.h.

config.h files make Mpg123 work for different systems. They're from audio-mpg123's source, copied from node-speaker's source when we forked it. The comments seem to explain how it works, but I haven't read through the files personally.

I haven't reproduced this error. It might not even be relevant anymore? There is several issues and incomplete parts of the bindings, though.

I would like to really understand deeply how each library component works and why you guys need/want it. Not in terms of audio capabilities level (as of yet) but just on a 'build' level for now.

I'll talk about Mpg123's setup, Cubeb's setup, then our setups.

Visit Mpg123's website for a lot of information. Mpg123 is hosted on SVN, so its mangled into git projects. audiojs/mpg123-mirror is @connorhartley's port to git and node-speaker includes mpg123 as a directory. See also API documentation for libmpg123 and libout123.

Mpg123 uses automake for its build, but it has to be reworked in node-gyp for our binding. Luckily node-speaker already did this (found in our fork here). If you feel motivated to rework the build of the binding, I'm open to ideas. For example, in Cubeb I've reached a simpler solution without node-gyp.

Clone Cubeb's repository and build its docs for information (I don't know any online sources unfortunately). Cubeb uses CMake for its build, so I've used cmake-js in the binding, which makes the entire thing much simpler.

Going forward with either one, it should use prebuild eventually, where instead of compiling source code when its installed, you install the compiled binary for your system.

Not sure what else to add here.

Another question I have potentially, does napi allow to switch versions without recompiling/rebuilding just to avoid the nan problem as seen on this issue?

You should recompile when switching Node versions. I've gotten errors about mismatched ABI versions several times. Not sure if it absolutely necessary, though.

The original issue could be related this. But, it would've been a local fix, and there is other issues with the bindings.

Is using napi with mpg123 instead of nan viable? Because if there's a missing win32 identifier problem (as the error states) maybe there's a wrong abi (configured for 64bit) and some value is not being read. I might be talking nonsense but I just want to gauge the surface and learn more. What are your thoughts?

It is! We have an incomplete branch for this, which you are welcome to continue, or start your own.

I would rank all the options we have like this:

Cubeb + N-API
Mpg123 + N-API
Cubeb + NAN
Mpg123 + NAN

Any of these are acceptable if its more stable/complete than what we have now. Just points to be made about which are better.

One thing is for sure, implementing a new cubeb cross-platform with napi will be somewhat groundbreaking. I think of all those native speed low latency audio streaming possibilities. Or maybe the new features you're after for the speaker output are different. First thing is first though. Once I cover all possibilities that may cause the error as it pertains to the gyp mgpg123 binding and the configure command, I'll move onto other things.

Definitely!

I want to stress the point: Mpg123 and Cubeb are alternatives to doing the same thing. Cubeb arguably does it better. Mpg123 is already began and undergone testing. But we need to choose one of them to use in audio-speaker.

I don't have complete insight in how Web Audio API, Mpg123, and Cubeb stack up against each other with their performance and features, but in my opinion, Web Audio API looks pretty robust as it is, we should use it where we can, and Cubeb where we can't.

First thing is first though. Once I cover all possibilities that may cause the error as it pertains to the gyp mgpg123 binding and the configure command, I'll move onto other things.

If you want to champion both of bindings, keep in mind we can only use one for audio-speaker.
