[FFmpeg-user] unicast input to ffmpeg

I'm trying to to merge a video and audio stream with ffmpeg.
I can successfully work with a multicast input for ffmpeg as in:

ffmpeg -i udp://@ -vcodec copy -i http://mp3stream1.apasf.apa.at:8000/ -acodec copy /muxed.mov

However I'd like to use an unicast stream as input for ffmpeg. The unicast is created with vlc directed at ([...] standard{access=udp, mux=ts, dst=, port=5353} [...]) and can be opened with vlc on the machine its directed at ( by simply opening udp://

Now when I try to open udp:// with ffmpeg as in:

ffmpeg -i udp:// -vcodec copy -i http://mp3stream1.apasf.apa.at:8000/ -acodec copy /muxed.mov

ffmpeg just sits there and does nothing. I already thought about piping the stream with openRTSP but that would be my fallback option.

Has anyone encountered this same behavior or does someone know what I am doing wrong?

I'd be glad for any input on this topic.


Best Regards
