## Perform the MLD based analysis on the CUT outputs on reference platform (Ubuntu 24.04)

## Perform analysis on the reference platform (Ubuntu 24.04)

   If CUT test execution is done on a different platform, the scripts/CUT_OUTPUTS must be copied and provided in the reference platform's scripts/CUT_OUTPUTS. Then the following command is used to perform MLD based analysis on the same, encoded outputs will be implicitly decoded using reference decoder executables and MLD analysis performed on the reference decoded outputs.

If CUT test execution is done on a different platform, the scripts/CUT_OUTPUTS must be copied and provided in the reference platform's scripts/CUT_OUTPUTS. Then the BE analysis or non-BE analysis procedure below should be followed.

### Perform the BE comparison on the CUT outputs on reference platform 

The BE comparison is performed to the CUT outputs using the command below. Encoded outputs will be decoded using the reference decoder executables as part of the process. The BE comparison is then performed between the CUT and reference decoded outputs. This includes comparison of ".wav"-files, and ".csv" and ".met" metadata files. If any non-BE results are observed, this is reported on the command-line and link to an analysis ".csv" file is given. The analysis file shows which exact files were non-BE.

```shell

PYTHONPATH=scripts python scripts/ivas_conformance/runConformance.py --testvecDir $PWD/testvec --ref_build_path=testvec/bin --analyse --be-test

```

### Perform the MLD based non-BE analysis on the CUT outputs on reference platform (Ubuntu 24.04)

The MLD-based non-BE analysis is performed to the CUT outputs with the command below. Encoded outputs will be decoded using the reference decoder executables as part of the process. The MLD analysis is then performed between the CUT and reference decoded outputs. Comparison to MLD corridor is also done as part of this process. The example output is also shown below.

```shell

PYTHONPATH=scripts python scripts/ivas_conformance/runConformance.py --testvecDir $PWD/testvec --ref_build_path=testvec/bin --analyse

```
