-    Supports WAV and FLAC formats with both synthetic audio (audiotestsrc) and hardware capture (pulsesrc).
+    Tests 10 scenarios: 4 encode (2 audiotestsrc + 2 pulsesrc) + 6 decode (4 playback + 2 OGG/MP3).

     Duration controlled via AUDIO_DURATION (default 10s): audiotestsrc uses num-buffers, pulsesrc uses timeout.
