MediaPlayer audio inquiry

[leeyunjai82]

Hi, everyone. I use i2s mic, raspberrypi camera and raspberrypi. I want to use my mic and camera in MediaPlayer Function for videocall of janus-gateway

no audio traffic, video ok Please check if I have set MediaPlayer().audio up wrong

Thank you ''' media = {'audio': True, 'video': True}

vplayer = MediaPlayer("/dev/video0", format='v4l2', options={'framerate':'5', 'video_size':'320x240'})
if media['video'] and vplayer and vplayer.video:
    pc.addTrack(vplayer.video)

aplayer = MediaPlayer("sysdefault:CARD=sndrpii2scard", format="alsa", options={'channels':'2', 'sample_rate':'44000'})
if media['audio'] and aplayer and aplayer.audio:
    pc.addTrack(aplayer.audio)
    media['audio'] = True

'''

Result if media['audio'] set True --> no audio traffic video ok

Please check if I have set it up wrong
