I want to download RTP pcap with opus payload type. I find an example file at here. Sampling rate and number of channels in this opus encoded packet respectively are 48000 KHz and 2. I want to check extra opus packets with another valid values for this parameters. Where can I find these files or How can I generate them?
Use ffmpeg to generate the opus pcap :
ffmpeg -f dshow -channel_layout stereo -i audio="Microphone Array (Realtek High Definition Audio)" -c:a libopus -ab 48k -f rtp rtp://IP-Address:PORT
Change the Name Audio input device based on your PC's Audio device.
