Hey guys - Im trying create a basic pipeline that just applies a filter to an input audio signal before outputting it. I'd also like to be able to dynamically change the filter parameters while the pipeline is running.
I'm having a few issues that I'm hoping you can help me with:
1) The filter doesn't actually seem to be doing anything - The pipeline is just passing the audio straight through, unfiltered. When I change the cutoff frequency and re-compile, the audio output is unchanged.
2) I can't dynamically change the cutoff frequency. Whenever I call "g_object_set (G_OBJECT (filter), "cutoff", cutoff, NULL);" to change the cutoff frequency I receive the following warning:
(pipe:1703): GLib-GObject-WARNING **: IA__g_object_set_valist: object class `GstAudioChebLimit' has no property named `h\xf3\u0015'
Do you guys have any idea I'm doing wrong here? I think there's probably something wrong with the way I initialize the elements - but Im not really sure how to fix it.
I've uploaded my source code
pipe.c - Its just a modification of the "hello world" application from the manual:
