Comment (by DonMoir):

 ...
 AVFilterContext *sink;
 ...
 if (type == AVMEDIA_TYPE_VIDEO) {
     ...
     ... ok sink set
 }
 else if (type == AVMEDIA_TYPE_AUDIO) {
     ...
     ... ok sink set
 }
 else {
    sink not set - remove test for audio if only can be video/audio
 otherwise maybe
    skip it, error, set to null, or who knows.
 }

 lavfi->sinks[i] = sink;
