Description Wellington Wallace 2018-02-12 13:35:39 UTC
Hi GStreamer developers! I would like to use the convolver from Linux Studio Plugins http://lsp-plug.in/?page=manuals&section=impulse_responses_stereo in my application https://github.com/wwmm/pulseeffects. But although the plugin is successfully loaded by GStreamer there are two parameters that are not show in the output of gst-inspect-1.0. The ones used to load the impulse response file for each channel. In the plugin ttl file they are defined as:

lsp_p:ifn0
        a lv2:Parameter ;
        rdfs:label "Impulse file 1" ;
        rdfs:range atom:Path
        .

lsp_p:ifn1
        a lv2:Parameter ;
        rdfs:label "Impulse file 2" ;
        rdfs:range atom:Path

I took a look at the lv2 plugin sources and it seems that there is no support for lv2:Parameter. So this may be the reason why they are not shown in the output of gst-inspect-1.0. 

Although I would like to help I just don't have the knowledge to do that yet. I have never worked at GStreamer lower levels and I know nothing about the LV2 api.

I am open to alternative solutions in case this is a feature we can't have any time soon.

Best regards,

        Wellington
