在Gstreamer（C＃）中使用管道播放音频

Question

I've been struggling with GStreamer for a while because I can't find any C# examples/tutorials.

As far as I know, Gstreamer uses pipelines in order to decode and then be able to send, for instance a song, to the speakers, but I tried the following, which didn't work:

        Gst.Element pipeline;
        string path = @"some_path.mp3";
        string command = "filesrc location=" + path + " ! oggdemux ! vorbisdec ! audioconvert ! gconfaudiosink";
        pipeline = Gst.Parse.Launch(command);
        pipeline.SetState(Gst.State.Playing);

However, it raises an exception in the Gst.Parse.Launch line

Does anyone know any good application example, and/or can actually post some code, so I can start getting used to the library? Also, if you can tell me what's wrong on the code above, I'd be thankful

Without further ado, Regards

Answer 1

Just change your command string to "filesrc location=" + path + " ! decodebin2 ! gconfaudiosink", that should work.

On a side note you should use the gst-launch tool on the command line to check if your pipeline is working and to debug it. Also use gst-inspect to find which plugins are available on your system and what is their functionality.
