I'd like to be able to press a button to play a sound of a button being pressed while music is already playing. SoundPlayer is no help because it stops the music to play the sound.
I have added the sounds to my Resources (WindowsFormsApplication2.Resources.Properties.button) and I don't want to have to type in the file location.
Answer from MerickOWA
You CANNOT play two sounds at once using SoundPlayer.
SoundPlayer is using the native WINAPI PlaySound function to accomplish the task which has no support for playing simultaneous sounds. Creating multiple instances of SoundPlayer won't help.
There are many options most of which involve implementing a lot of the low level API to window's native audio library or DirectSound (note neither are C# and require alot of interop code)
The simplest option would be to depend on windows media player to play the audio for you.
Add a reference to "C:\Windows\System32\wmp.dll"
then use
var player = new WMPLib.WindowsMediaPlayer();
player.URL = #"..\..\bin\debug\tribal dance.wav";
Note: play starts immediately after setting the URL property
The down side of this approach is your reliance on media player for your application to work properly. On the upside, you can use any file format media player supports.

I want to record sound to a file and at the same time I want to be able to play audio from the same file in C#
For example, play the last 15 seconds but the microphone has to keep on registering and recording while replaying.
Is this possible and in that case, which is the best approach to do this?
The answer is YES, and you should play around with low level audio API, namely WaveIn/Out functions from winmm.dll, through P/Invoke in C#.
In short words, you need to use WaveIn to capture input signal from a input device and store in some structure, then use WaveOut to play back the audio simultaneously, or some delay after.
Here is a project you can start with: a duplex audio player. You can download the project and play around with it and see how it achieves it, then do some modifications upon the project to achieve what you want :)
I have a mp3 file. I have a background sound file like rain sound or some fire sound. I want to play these two files parallel in the app as well as in background. So that it looks like a single music is playing a story with a background. Please provide any guidance to achieve this.
AFAIK there are four ways to play audio in WP: BackgroundAudioPlayer, MediaElement, SoundEffect, Microsoft Media Foundation. As for your question:
BackgroundAudioPlayer - it won't work, as there is only one Instance of BAP on the phone. So to play a different file, you have to change Track's Source, so it won't handle two at the same time.
MediaElement - it's also a bad idea (it won't also run with BAP simultanously), because as MSDN says:
When a MediaElement control plays audio or video content, any background sounds or media already playing are halted. The app launches the playback experience when the user taps the control. Only one MediaElement control can operate at a time.
you can try to play many sounds using SoundEffect (thougt as Documentation says it can be only a wave file), I won't post code here, because there are already many examples: one, two, three
as for Microsoft Media Foundation: Walkthrough, Programming Guide, Supported file formats
I want to be able to precisely control the timing of .wav files played in my program. I also want to be able to play more than one .wav file at the same time. The SoundPlayer was not good enough because I can't play two sounds at once, and even when I play different sounds consecutively, there is about a 1/8th second delay between each sound, which is unacceptable for what I am doing. I cannot find a way to add a Device using SharpDX.
You have a directsound sample in sharpdx, should get you started.
Also you can have a look at NAudio , which should also fit your needs and be a bit easier to use.
I want to build application which needs to be able to capture video from a web camera using C#. The captured video should be compressed using some codec (nothing special, anything available that saves space) and written to a file while capturing. A live preview of capture is not necessary.
The first question is: Which API is suitable for this and what would you recommend (I have seen DirectShow, Windows Media Foundation wrapper, etc. I am not sure which is would be best for managed environment and C#)?
I also need a video player in WPF which will play captured video. This player must be able to play captured video from an arbitrary position, pause and start/stop video.
Putting it all together, video is captured from a webcam in the background and at the same time the player plays that video being captured, but it can be paused, re-winded, stopped - something like a modern DVR.
The second question: Is it possible to create such a player using WPF MediaElement? (Confusion is about the file which is at the same time filled from the capture and played in the player)
A nice example of how to make all what you want: WebCam
I have used the AForge set of libraries to accept the videos frame by frame. I used the private void videoSourcePlayer1_NewFrame(object sender, ref Bitmap image) function to do this.
I've used VlcDotNet. It is very flexible and simple to use. It has a pretty active user base as well.
I've used it for displaying live video streams as well as recording to files.
You can try the DirectShow.net library.
I can recommend WPF's ffmediaelement. It's built on FFmpeg. So what can FFmpeg, can also ffmediaelement. It can capture video from both the webcam and the capture card. Unlike DirectShow, it's very simple.
Here's how to set up a video source:
Media.Source = new Uri("device://dshow/?video=Osprey-460e Video Device 1C");
... and parameters for it in MediaOpening event:
Media.OnMediaOpening(s, e) =>
{
e.Options.Input["framerate"] = "25";
e.Options.Input["video_size"] = "768x576";
e.Options.Input["pixel_format"] = "yuyv422";
};
I have created a movie player. I'm using the default windows control for Media Player. However I just saw that some movies do not work under it(some FLV files). However those files do work under Media Player Classic. So I was thinking about using the Media Player Classic control.
However
I want this movie player to be as portable as possible. So what I would like to do is to use Media Player Classic control when its available in system, but if its NOT than use Media Player control.
Is that even possible or do I need to create two applications that share the same code?
I would recommend using libvlc. VLC is really good about playing almost anything you give it. It is a C API but one could possibly DllImport their way to success and write code in C#.
Here are some good resources to get you started:
