I am trying to run master_me as part of an ffmpeg chain:

ffmpeg -i shittyaudio.wav -af 'lv2=plugin=https\\://github.com/trummerschlunk/master_me' shittyaudio_masterme.wav  -y

What seems relevant here is Options feature missing, cannot continue!. Looking at the ffmpeg LV2 filter help it seems that I am supposed to pass in mandatory controls (which are Options in lv2 speak?) to the plugin. However, I am a bit puzzled as to what that may be. filter.ttl has

    lv2:requiredFeature opts:options ,
                        <http://lv2plug.in/ns/ext/urid#map> ,
                        <http://lv2plug.in/ns/ext/worker#schedule> ;

but I am a bit lost here.

Once this works I can finally (!) try master_me with the VOC pipeline so any pointers are very much appreciated.

the host side needs to implement https://lv2plug.in/ns/ext/options, that is the opts:options part.
I guess ffmpeg does not have support for this in its lv2 hosting code.

danimo commented

Ah, bummer. In the meanwhile, do you know if I would I get away with compiling the ladspa version of master_me?

danimo commented

(Implementing lv2 suppor in ffmpeg may be feasible, but rolling out that patched ffmpeg might not be)

falkTX commented

if ffmpeg supports ladspa, sure. the latest release of master_me officially supports ladspa already.
