[FFmpeg-user] IP camera stream video with audio

[Gabor Alsecz]

Dear All,

I have 2 types of IP cameras (Bosch Dinion UHD, Samsung PNO9080) and both
capable of audio streaming alongside with video when attach MIC to it. On
it's own web server showing audio has input signal so should work
theoretically.
I can grab video but not audio? What should i do here?
I opened stream - of Bosch - with ffplay like this:
ffplay rtsp://192.168.1.105/rtsp_tunnel

Console output:
