You mean "libvlc_media.add_option(options, ref ex);"? I tried setting the options as you said, but it doesn't work. What does the "SID" mean? Is it the program ID of the TS stream? But the program ID is always changing.You are setting up the frequency and the other stuff, by adding mrl-options to your mediadiscriptor, right? Then you just have to add ":programs=[SID]" as option to your mediadiscriptor objekt.
I would suggest using this wrapper instead:Hi guys:
Sorry if is not the correct forum, but I'm very interesting in use and help with the .NET interface for VLC, so my question is where can I get a fresh copy of the source or where can a check out the last version (svn repo?).
both wrappers work, with some few modifications. i am going to post my changes to the meedios wrapper in the corresponding thread.1) I'm a c#/mono programmer so I wonder if someone test this libvlc wrapper in c# on linux?
no2) the current wrapper is not a wrapper arround a ActiveX control right?
no3) the native function wrappers are also in C# not VS.NET C++ right?
and finally...
does work, by adding stream output options to the mrl.4) what is the current status of the vlc streaming capabilities of LibVlc and/or the .NET wrapper?
SID is the service identifier that should be in any DVB stream. Imho it describes the Video and Audio PIDs belonging to a channel.You mean "libvlc_media.add_option(options, ref ex);"?

Hi Marx!Sorry, I've been busy on project work. I'll be releasing the source of the Media player interface and wrapper soon.
Is there missing an implementation of libvlc_media_list_player in the Marx C# Wrapper?Can someone sketch how to create and use a Marx_libvlc_media_list object?

does anyone konw how to do like this about changing the libvlc_new() function of the parameter args?Good job done here.
One thing I found that was a problem for me working with non-english/unicode/UTF-8 filenames is that VLC wouldn't play the file.
To solve this problem... we need to modify the type of the filename string as shown below.
[DllImport("libvlc")]
private static extern VLCMediaHandle libvlc_media_new(VLCCoreHandle vlcCoreHandle, [MarshalAs(UnmanagedType.LPArray)] byte[] mri, ref VLCExceptionDetails ex);
Because the original C++ function definition was: char*, it is not completely accurate to send Uris into libvlc.dll as string. A String type in C# is Unicode (UTF-16) while libvlc.dll uses UTF-8! So no non-english Uris!!!
The code above solves this problem. To set a new media do this.
UTF8Encoding utf8 = new UTF8Encoding();
vlcMediaHandle = libvlc_media_new(vlcCoreHandle, utf8.GetBytes(link), ref ex);
Code: Select all
[DllImport("libvlc")]
private static extern CoreHandle libvlc_new(int argc, string[] args, ref ExceptionStruct ex);
