@rsanchez87 @rgonzalezfluendo aren't there another PR that implements additional changes on top of my PR #321 which waits for Andoni's review? |

- `TestVector`: new optional `decoder_config` dict field, serialised to/from JSON only when present (same pattern as `profile`). - `Decoder.decode()`: extended abstract signature with optional `decoder_config` parameter (backward-compatible default: None). - All `Decoder` subclasses updated to accept and forward the parameter. - `GStreamer`: `FluendoFluAC4DecGst10Decoder` overrides `gen_pipeline` to consume `decoder_speaker_config` from `decoder_config`. - `utils`: `compare_byte_wise_files` extended with WAV-aware comparison that filters silent reference channels and compensates for stream lag, used by the AC4 byte-wise conformance check. - `AC4_ELEMENTARY_STREAMS`: test vectors updated with `decoder_config` carrying the required `decoder_speaker_config` per stream. - New sample comparison method for AC4 - Remove IMS test vectors from AC4 test suite - Decouple reference comparison tests from byte-wise dispatcher (utils)
- The mapping from optional_params into a decoder property must be done in the decoder implementation.
