C# WPF application crashing when playing 16 players

I am running into an issue with my C# WPF application crashing silently when I am trying to play on 16 VideoViews. I did not see any error messaged popup, nor did I see anything in Windows Event viewer.
Each player instance have WindowsFormHost and hosting a VideoView in that and I am playing RTSP streams on them.
Crash time is not fixed, sometimes it crash after 2 hours, and sometimes after 7-8 hours.
Core.Initialize(AppInfo.VlcDir.FullName);
private LibVLC libVlc = null;
private LibVLCSharp.Shared.MediaPlayer mediaPlayer = null;
this.libVlc = new LibVLC(this.GetParsedPlayerOptions().ToArray());
this.mediaPlayer = new LibVLCSharp.Shared.MediaPlayer(this.libVlc);
this.videoPlayer.MediaPlayer = this.mediaPlayer;
this.mediaPlayer.Volume = 0;
this.mediaPlayer.EnableKeyInput = false;
this.mediaPlayer.EnableMouseInput = false;
// Then I added a bunch of event handlers for VideoView and MediaPlayer.
// Then I have a different function which plays videos
if (this.mediaPlayer != null)
{
var media = new Media(this.libVlc,GetPlaybackStreamUrl(this.Server), FromType.FromLocation);
this.mediaPlayer.Media = media;
this.mediaPlayer.Play();
try
{
media.Dispose();
}
catch
{
}
}
Please let me know if you need any more information.
Any suggestions of what I could be doing wrong, or anything missing?
I am running on Windows 10. Visual Studio 2019, application compiled as X86.
I am not able to find the option to upload log file, but I did attach that to the issue on videolan forum, which can be found here: https://code.videolan.org/videolan/LibVLCSharp/-/issues/564
Thanks.

I was not able to find the problem with the code or the crash stack for where it's dying.
But I was able to fix the problem by increasing the address space, by using editbin to add /LARGEADDRESSSPACE to process post build.

Intel Real Sense Audio Not Coming

Am recording the video by intel real sense camera. The video recording is done and working successfully. But audio is not coming in that video.
For that my question is...
My configuration is Lenovo Yoga 15 with internal real sense camera
I want to install audio driver for sound ? Is that are required ?
please give me some suggestion.
session = PXCMSession.CreateInstance();
senseManager = session.CreateSenseManager();
senseManager.captureManager.SetFileName("new4.rssdk", true);
senseManager.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR, WIDTH, HEIGHT, 30);
senseManager.Init();
for (int i = 0; i < 200; i++)
{
if (senseManager.AcquireFrame(true).IsError()) break;
PXCMCapture.Sample sample = senseManager.QuerySample();
senseManager.ReleaseFrame();
colorBitmap.Dispose();
}

I didn't understand the question well, so do you want to run audio and record the video together?
If yes, you have to create an instance of the class responsible for doing that.
take a look here Speech Recognition
I used two threads in order to do that. I have an application where I use facial recognition and audio recognition. I decided to split them and it worked very well.

Aforge and CyberLink YouCam , camera not start

I work on project that capture an images from webcams using C# and Aforge.
When the camera is a 'CyberLink' i get this frame from the camera:
The code that you see here is only part of my code of course, but it demonstrates my use in Aforge.
Get all cams on this PC:
var webCam = new FilterInfoCollection(FilterCategory.VideoInputDevice);
var cams = new List<VideoCaptureDevice>();
foreach (FilterInfo camInfo in webCam)
{
var cam = new VideoCaptureDevice(camInfo.MonikerString);
cam.NewFrame += NewFrameHandler;
cams.Add(cam);
}
I have a timer that every few minutes starts the camera like this:
foreach (var cam in cams)
{
cam.Start();
}
When i get the event 'NewFrame' i call to my function 'NewFrameHandler' to save the frame and close the camera:
var bit = (Bitmap)eventArgs.Frame.Clone();
bit.Save("#c:\Cam_" + DateTime.Now.Ticks + ".png", ImageFormat.Png);
foreach (var cam in cams)
{
cam.SignalToStop();
}
As i say the code works great, only when the camera is CyberLink i have this problem.

I removed the youcam software and now I get the frames properly.
Would love to hear if anyone has a more elegant solution.

The YouCam software may hijack the stream, and removing it may be the only option. You could also check if YouCam offers an API of its own that allows you to interface with the camera. I have used AForge before and it worked great with the Logitech cameras I was using. Your code looks good to me, though it was a year or two ago when I was using AForge.

Pausing and resuming mp3 with WMPLib and C#

I'm working on a simple mp3 player project with C# and the WMPLib library. The idea is to make it controllable with a PIC component, to control media playing in the PC from "anywhere" in my house (yes, this is a college project).
The problem: I can't get the WindowsMediaPlayer.controls.play() method to resume a paused playback. How should I do it?
I've already tried to save and set the WindowsMediaPlayer.controls.currentPosition property, but it doesn't work.
PS:
The same problem: http://social.msdn.microsoft.com/Forums/en-US/windowspro-audiodevelopment/thread/770d22fc-7ef1-475e-a699-b60e2282a7c7/
Different problem: pause and resume Windows Media Player in C#
Thanks in advance
EDIT: WindowsMediaPlayer.controls.currentPosition works fo setting the position, but not for getting it:
double time = Player.controls.currentPosition; //Returns 0 always
Player.controls.currentPosition = time; //Works fine, makes music jump to time seconds

...
double time = Player.controls.currentPosition; //return always 0 for you, because you pause first and after get the value
Player.controls.pause();
Player.controls.currentPosition = time;
Player.controls.play();

You can get currentposition by converting it to string for example:
label1.text = convert.tostring(Player.controls.currentPosition);
I've used a label to show you the exactly currentPosition value.

How to mute the microphone c#

I wanted to know, what would the coding be if I wanted to toggle mute/unmute of my microphone. I am making a program that can run in the background and pickup a keypress event and toggle mute/unmute of the mic. Any help with any of that coding would be very helpful. I am pretty new to C#, and this is just a really simple program I wanted to make. That is all it does, is it will listen for keypress of the spacebar, even when the program is in the background, then when the spacebar is pressed it will mute/unmute the mic.
Thank you for any and all help!

For Windows Vista and newer, you can no longer use the Media Control Interface, Microsoft has a new Core Audio API that you must access to interface with audio hardware in these newer operating systems.
Ray Molenkamp wrote a nice managed wrapper for interfacing with the Core Audio API here:
Vista Core Audio API Master Volume Control
Since I needed to be able to mute the microphone from XP, Vista and Windows 7 I wrote a little Windows Microphone Mute Library which uses Ray's library on the newer operating systems and parts of Gustavo Franco's MixerNative library for Windows XP and older.

You can download the source of a whole application which has muting the microphone, selecting it as a recording device, etc.
http://www.codeguru.com/csharp/csharp/cs_graphics/sound/article.php/c10931/

you can use MCI (Media Control Interface) to access mics and change their volume system wise. Check the code below it should be setting volume to 0 for all system microphones. Code is in c; check pinvoke for details on how to translate this code to c#
#include "mmsystem.h"
...
void MuteAllMics()
{
HMIXER hmx;
mixerOpen(&hmx, 0, 0, 0, 0);
// Get the line info for the wave in destination line
MIXERLINE mxl;
mxl.cbStruct = sizeof(mxl);
mxl.dwComponentType = MIXERLINE_COMPONENTTYPE_DST_WAVEIN;
mixerGetLineInfo((HMIXEROBJ)hmx, &mxl, MIXER_GETLINEINFOF_COMPONENTTYPE);
// find the microphone source line connected to this wave in destination
DWORD cConnections = mxl.cConnections;
for (DWORD j=0; j<cConnections; j++)
{
mxl.dwSource = j;
mixerGetLineInfo((HMIXEROBJ)hmx, &mxl, MIXER_GETLINEINFOF_SOURCE);
if (MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE == mxl.dwComponentType)
{
// Find a volume control, if any, of the microphone line
LPMIXERCONTROL pmxctrl = (LPMIXERCONTROL)malloc(sizeof MIXERCONTROL);
MIXERLINECONTROLS mxlctrl =
{
sizeof mxlctrl,
mxl.dwLineID,
MIXERCONTROL_CONTROLTYPE_VOLUME,
1,
sizeof MIXERCONTROL,
pmxctrl
};
if (!mixerGetLineControls((HMIXEROBJ) hmx, &mxlctrl, MIXER_GETLINECONTROLSF_ONEBYTYPE))
{
DWORD cChannels = mxl.cChannels;
if (MIXERCONTROL_CONTROLF_UNIFORM & pmxctrl->fdwControl)
cChannels = 1;
LPMIXERCONTROLDETAILS_UNSIGNED pUnsigned = (LPMIXERCONTROLDETAILS_UNSIGNED)
malloc(cChannels * sizeof MIXERCONTROLDETAILS_UNSIGNED);
MIXERCONTROLDETAILS mxcd =
{
sizeof(mxcd),
pmxctrl->dwControlID,
cChannels,
(HWND)0,
sizeof MIXERCONTROLDETAILS_UNSIGNED,
(LPVOID) pUnsigned
};
mixerGetControlDetails((HMIXEROBJ)hmx, &mxcd, MIXER_SETCONTROLDETAILSF_VALUE);
// Set the volume to the middle (for both channels as needed)
//pUnsigned[0].dwValue = pUnsigned[cChannels - 1].dwValue = (pmxctrl->Bounds.dwMinimum+pmxctrl->Bounds.dwMaximum)/2;
// Mute
pUnsigned[0].dwValue = pUnsigned[cChannels - 1].dwValue = 0;
mixerSetControlDetails((HMIXEROBJ)hmx, &mxcd, MIXER_SETCONTROLDETAILSF_VALUE);
free(pmxctrl);
free(pUnsigned);
}
else
{
free(pmxctrl);
}
}
}
mixerClose(hmx);
}
here you can find more code on this topic
hope this helps, regards

I have several microphones in win7 and class WindowsMicrophoneMuteLibrary.CoreAudioMicMute is incorrect in this case.
so I change the code and works great because now his cup Whistle all microphones and not just in the last recognized by win7.
I am attaching the new class to put in place.
