Have a look at this library.

I would like to write a gstreamer pipeline that mixes the audio from two sources. I then want to be able to select an audio source from an app on my computer, i.e. Discord, such that the mixed audio will play as if it was coming from my mic.
It seems simple enough to get the mixing right, but it seems like I need to use something like Virtual Audio Cable to achieve the second part. Is there a way to do this entirely in gstreamer or with something more lightweight than installing Virtual Audio Cable?
There is no [yet] Windows API to create virtual audio endpoint, so that applications could interact with it similarly to real device. Consequently, there is no GStreamer wrapper over this non-existent API either.
Doing it without VAC would require that you still install an audio driver where you would provide your own endpoint for Windows to use and expose to applications.
I'm currently building a project on C++ using Visual Studio on Windows 8. This application captures video from camera and triggers some virtual animations in real-time, with some sounds being played along with the animations.
The user has the option to record the experience in video and sound. I already am able to record video, now I want to create a audio track of the sounds that are being played by the application, to later fuse both video and audio files.
So, which is the best way to record audio output from an application in windows?
Let me stress that I do NOT want to record audio from any input devices (such as a microphone), only from the application itself.
Best regards.
There is no recording of application output. If you generate audio on your own, you make a copy for the recording purposes, mix if you have multiple sources, and then use one of the APIs to produce a file depending on your preferences: directly writing a WAV file, Windows Media audio files (ASF/WMA), DriectShow, Media Foundation, third party libraries.
Real playback audio data is being mixed and sent for further playback. Sometimes you can enable loopback recording to capture fully mixed output (not just of specific application through) as if it is a capture from realtime audio input device.
I have a standard speaker and a bluetooth speaker. I want to play a simple wav file on both speakers simultaneously under window xp or windows 7. Is any way I can do it using c++? Thanks.
Also there are libraries out there to make it possible playing multiple sounds in a time.
irrKlang is one of them.

It has very good samples if you want to start.
Can someone point me some c++ samples or some c++ librarys that can transport video and voice over a LAN network.
My objective is to activate a web cam in another pc and receive in my pc the video and voice of the another pc (this can be only one way or in both ways pc to pc call, but i only need one way for now, only see and hear not to interact).
Thanks
If working on Windows try out the NetMeeting Resource Kit. It probably limits playing your videos with Windows Media Player only.
VNC and all its variants should be able to do it.
TightVNC Free.
Another VNC Project
I can't locate a source code link right now, but if you search with vigor it should be revealed.
WebEx's entire business was built on a forked version of VNC. Fun.
Im currently using wxMediaCtrl to play videos in my app. The api is unfortunately a little buggy, and doesn't playback all media types i need to support (e.g. wmv).
I am wondering if there is an alternative c++ api, that will allow me to do this. I am currently just concerned with supporting windows.
What do people normally use to embedd video in their apps? Also i need to be in control, i.e. tell the video, where to play in time, pause/stop, i dont need any shuttle controls, as i have my own.
Thanks in advance.
wxMediaControl uses DirectShow on Windows, it should be able to play wmv files. If you can play a media file with GraphStudio, you should be able to play it with wxMediaControl.
If not, you need to install the proper video codecs. Have you tried installing FFDShow?
You can try Video Control, and here is a sample on how you can play a video file.
If you want something without DirectShow, you can take a look at VLC ActiveX.
As a word of caution regarding the use of GPL plugins (FFDShow or VLC ActiveX) in non-GPL applications you should read this.
Qt uses Phonon for cross-platform media playback. On Windows Phonon utilizes DirectShow, so it can play anything Windows can (.wmv). It has all the capability you mentioned. It's also very easy to implement and use. I recommend highly.
