Play a list of ogg

[Crevetolog]

Hi, I search a way to play a list of indexed ogg with gst-launch (in fact it's in a code).

I'm developing an addin for tomboy which add voice notes to tomboy, it's working with gstreamer but I'm trying to add a new functionality which need to read indexed ogg files in order, one by one, like that :
"play(name_of_the_note.0.ogg) -> playing over -> play(name_of_the_note.1.ogg) -> etc..."

I have a function "Play(filePath)" which works but if I do a for() loop for all the voice notes, that play all ogg together so I searched in gstreamer plugins list a way to do what I want but didn't find.
I tried to use Threads in C# but didn't worked.
I saw the plugin multifilesrc which read indexed files but I didn't find other than PNG images examples with that, no example with sound files or other.

I would like to know if there is a way with gst-launch (the command line tool) to play a list of file one by one.

Thanks.


My Play() function and the bus callback if someone is interested (it's in C# using Gstreamer-sharp):

public void Play(string filePath)
{
int status = GetState();

/* 
 * get the state of the pipeline 
 * 0 : null 
 * 1 : playing 
 * 2 : Paused 
 */

			if(status == 2)
			{
				pipeline.SetState(Gst.State.Playing);
			}
			else
			{
				
				string command = "filesrc location="+filePath+" ! oggdemux ! vorbisdec ! audioconvert ! gconfaudiosink";
				pipeline = Gst.Parse.Launch(command);	
				SetBusCallback();
				pipeline.SetState(Gst.State.Playing);
			}
}
private bool BusCallback(Gst.Bus bus,Gst.Message message)
		{
			switch (message.Type) 
			{
			    case Gst.MessageType.Eos:
					status = Gst.State.Ready;
					pipeline.SetState(status);
	
			      	break;
				case Gst.MessageType.Error:
					status = Gst.State.Null;
					pipeline.SetState(status);
				break;
			    	default:
				break;
			}
			return true;
		}

PS: sorry for my english if I made some mistakes.

You haven't attached the full example. But you should just play then
next item, when you get "Gst.MessageType.Eos" on the bus.

You find the solution, call the play() methode in the buscallback. Works great now ! Thanks !

But now I would like to add a function that merge every ogg of the list into one ogg, the final goal of that is to add a button into my addin to save the voiceNote where you want but to do that I need to transform the list of ogg into one big ogg.
I search a way to do that with gst-launch.

you could use gnonlin. If you do this manualy you need to handle several
details correctly (eat intermedia eos events from sources and use
newsegment events to create a continous output).
