Hi,
I'm trying to combine my sound card's input with my IP camera video (streamed via RTSP, using h.264 codec) and save it in a file. Do any of you have any experience with this?
This is the command I've tried:
# ffmpeg -y -r 30 -f rtsp -i rtsp://192.168.25.19/h264/media.amp?resolution=qvga -f alsa -ac 2 -i hw:0 -f mp4 -acodec libaacplus -ab 32k -ac 2 -vcodec copy video.mp4
