Salut J'essaie d'enregistrer le flux à distance reçu de la webrtc, j'ai suivi un échantillon de code de git, essayé diverses approches pour obtenir le flux à distance, mais pas en mesure d'obtenir un flux de socket ou autre ainsi, si quelqu'un a une idée s'il vous plaît suggérer ici est extrait de ma classe de WebRTCClientAndroid WebRTC enregistrer le flux à distance
ici est ma classe:
