Hey there,

Please add these flags for the flv muxer:  "-flvflags +*no_sequence_end*
+no_metadata+no_duration_filesize

In your example, test with:

ffmpeg -f lavfi -fflags +genpts -i anullsrc -rtsp_transport udp -i
"rtsp://user:password@192.168.1.124:554/Streaming/Channels/101" -bufsize
5M -tune zerolatency -vcodec copy -bsf:v dump_extra
-flvflags  +*no_sequence_end*+no_metadata+no_duration_filesize -f flv
"rtmp://$URL"

And report back.
