I'll take a look at KCP (thanks for mentioning it!).
I'm really taking SRT to the limit for when problems or connection
interruptions occur. Apparently the implementation of SRT within FFMPEG has
some problems that do not happen when I use SRT-live-transmit with output
to udp while reading this output in FFPLAY:


ffplay -hide_banner -nodisp -analyzeduration 0 -flush_packets 0 -probesize
32 -fflags nobuffer -f:a mpegts "udp://"

With this I achieve good results. I maintain the latency in 600ms even
after a connection interruption.
