Hi,  I am using rtmpsrc  and flvdemux to demux the rtmp stream and then send
video and audio with udp ,

My src stream does not have audio track sometimes,  in this case,  it will
stuck the pipeline.

Anyone can help me with this?

gst-launch-1.0 -v rtmpsrc location=rtmp://localhost/live/stream  ! flvdemux
name=demux demux.audio ! queue ! decodebin ! audioconvert ! audioresample !
opusenc ! rtpopuspay timestamp-offset=0  ! udpsink  host= port=5000
demux.video! queue ! h264parse ! rtph264pay timestamp-offset=0
config-interval=-1  ! udpsink  host= port=5002
