The VideoLAN Forums

Hi,

I need to embed VLC into my C# application so as to display the live video that is being captured by my web camera.

Anyone can help?


Thanks!

Sarah

Code: Select all

Functions.LibVlc vlc = new Functions.LibVlc(); vlc.Initialize(); vlc.VideoOutput = pictureBox1; vlc.PlaylistClear(); vlc.AddTarget("S:\\test.avi"); vlc.Play();

Thats the code I used to make it work. I did change the namespace in my applicaiton to Fucntions.LibVLC though so that line would need changed. Also pictureBox1 needs to be changed to the name of your picturebox.

That code just when inside the button clicked code.

Hope that helps.

How can I get the Stats information?

For example, using the following I can get the Meta Information from your .NET control:

const String Meta_information = "Meta-information";
public string GetMetaInfo(string strMetaParam) {
using (VlcObject vobj = new VlcObject
(this.vlcHandle, ObjectType.VLC_OBJECT_INPUT)) {
if (vobj.SubObject != IntPtr.Zero) {
IntPtr resultString = IntPtr.Zero;
input_Control(vobj.SubObject,
input_query_e.INPUT_GET_INFO,
Meta_information, strMetaParam, ref
resultString);
string res = Marshal.PtrToStringAnsi
(resultString);
return BaseTools.UTF8ToIso8859(res);
}
}
return "";
}

But a similar approach does not work for the Statistical Data from a stream?
For example, I tried to get the Statistical data using this function but it doesn't work:

const String Stats_information = "Stats-information";
public string GetStatsInfo(string strStatsParam) {
using (VlcObject vobj = new VlcObject(this.vlcHandle,
ObjectType.VLC_OBJECT_STATS))
{
if (vobj.SubObject != IntPtr.Zero) {
IntPtr resultString = IntPtr.Zero;
input_Control(vobj.SubObject,
input_query_e.INPUT_GET_INFO,
Stats_information, "Decoded blocks", ref
resultString);
string res = Marshal.PtrToStringAnsi
(resultString);
return BaseTools.UTF8ToIso8859(res);
}
}
return "";
}

Could you tell me how to get any of Statistical Information above using your .NET interface?
/* Input */ "Input"
