I try to stream live audio using
ffmpeg and external USB microphone. I followed this nearly tutorial
I had to adapt some steps but finally, I achieved to receive the stream my laptop using this command :
ffmpeg -f oss -i /dev/dsp1 -acodec libmp3lame -ab 32k -ac 1 -re -f rtp rtp://192.168.28.116:1234
The CPU is near 100%, i have a bad sound during two seconds and after nothing... I see in Wireshark that the board is sending frames continuously.
Does someone have ideas to lower the CPU usage ?
