            Bug ID: 793384
           Summary: lv2: Parameter metadata is not supported
    Classification: Platform
           Product: GStreamer
           Version: 1.12.4
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

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
