Hello again,
maybe someone could help a ffmpeg-newbie to get the correct hls-settings
(hope there is something possible without re-encoding). The GOP is
IPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP 31 CLOSED (got it from this script
https://gist.github.com/ragnraok/638023456771dc596e6f953b47061f0e).
Thanks,
Thomas

Hello,
I try to local restream https://herberts.meinekameras.de:10169
(rtsp-over-websocket) with this workflow: Go-script (proxy websocket to
rtsp) -> ffmpeg (rtsp to hls) -> xupnpd2 mediaserver -> vlc or TV.
It works good in vlc, but on the TV it plays too fast and there are
pauses. I tested all 4 hls-handlers (hls, hls2, hls3, hls4) in xupnpd2
with the same result.
ffmpeg command:
ffmpeg -re -rtsp_transport tcp -i
"rtsp://localhost:8554/axis-media/media.amp?overview=0&camera=1&resolution=1280x720&videoframeskipmode=empty&Axis-Orig-Sw=true&fps=15"
-c copy -f hls /home/user/lighttpd-install/htdocs/stream.m3u8
Hope that someone could test the workflow and maybe optimize the
ffmpeg-command.
Thanks,
Thomas
PS: I never had this issue in xupnpd2 when receiving hls-streams
directly from the internet.
