pas de piste son dans HandBrakeCLI

Bonjour à tous
Je souhaites convertir les vidéos faites avec mon appareil photo (Canon Powershot G9) à l'aide de HandBrakeCLI, mais celui-ci m'indique qu'il n'a pas trouvé de piste son. La conversion se déroule bien mais la vidéo résultante est muette (la vidéo d'origine a bien une piste son audible).

Voici ce que me donne le log de la conversion :
