I came across this message in the log when I was looking for something else:
2023/06/24 19:59:52.000511 [HLS] ffmpeg: ch6046-dTVE-DTV-ip127.0.0.1-remux: [hls @ 000000000319c800] Timestamps are unset in a packet for stream 1. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
Not sure if you are already aware of it.
