I executed the command
ffmpeg -list_devices true -f dshow -i dummy
to find out that the audio device is Realtek HD Audio Input. But executing the command
ffmpeg -f dshow -i audio="Microphone (Realtek HD Audio Input" -acodec libmp3lame -ab 128k -ac 2 -ar 44100 -re -f rtp://10:14:35:12:1234
gives the error
"Could not find audio device. audio='Microphone (Realtek HD Audio Input: Input/output error"
I have checked for the working of the microphone and it works well. Please let me know what is the issue here.
The machine runs on Windows-XP SP2.
