问题
A video camera is sending me video data as RTPs via UDP on a local port.
Does ffmpeg support automatically conversion of input (H.264 payload) to MP4 ?
How to do that ?
回答1:
This should work:
ffmpeg -i udp://localhost:1234 -vcodec copy output.mp4
Or try:
ffmpeg -i rtp://localhost:1234 -vcodec copy output.mp4
Replace 1234 with your port. I assume that the input is already in H.264, if not, remove the -vcodec copy.
