[FFmpeg-user] ffmpeg doesn't reconnect when capturing live connections

no real clue, but http and https inputs seem to have zero f'ing useful
countdown/timeout handling... nor "-t" counting.
I was trying something similar, like so:
$ while :; do ffmpeg -xerror -re -i
https://stream.nightride.fm/datawave.mp3 -filter_complex
"[0:a]avectorscope=s=640x518:r=24000/1001:mode=polar:scale=log,pad=1280:720[vs];
[0:a]showspectrum=mode=separate:color=intensity:scale=log:s=640x518[ss];
[0:a]showwaves=s=1280x202:mode=line:colors=0xffffff|0xffffff:n=2[sw];
[vs][ss]overlay=w[bg];
[bg][sw]overlay=0:H-h,drawtext=textfile=title.txt:reload=1:fontcolor=white:x=30:y=30:fontsize=36,fps=24000/1001[out]"
-map "[out]" -map 0:a -af
"aresample=48000:resampler=soxr,apad,adelay=190|190" -c:a ac3
-channel_coupling 1 -cpl_start_band 8 -b:a 112k -ac 2 -cutoff 21000
-c:v libx264 -preset veryslow -pix_fmt yuv420p -bf 4 -g 72 -b:v 512k
-maxrate 5M -bufsize 5M -aq-strength 2 -x264-params
"nal-hrd=vbr:ref=4:me=hex:me_range=1280:mbtree=0:aq-mode=1" -f mpegts
-flush_packets 0 "udp://localhost:1234?pkt_size=1316" ; sleep 1 ; done
[removed normal startup/runtime output..]
then after a while, whenever the stream/network/etc hangs but doesn't
close the tcp connection, we see shit like this - which, even with
-xerror, requires sending ^c a few times to force close; it seems like
some sort of easy failure to trap, but try as I might, can't find any
useful hints/clues:
