Maybe something like the following:
//Grab the first (and likely only) structure in the caps
GstStructure *st = gst_caps_get_structure (caps, 0);
// Test if it is WAV
gboolean is_wav = gst_structure_has_name (st, “audio/x-wav”);
// Test if it is MP3
gboolean is_mpeg = gst_structure_has_name (st, “audio/mpeg”);
gst_structure_get_int (st, “layer”, &mpeg_layer);
gboolean is_mp3 = is_mpeg && mpeg_layer == 3;
Or you could use decodebin which will automatically choose the correct decoder for you.
