[FFmpeg-user] Problem with ffmpeg command when recording live streams

[Yanet Giuse]

Hello!I am trying to record a live rtsp stream and save videos locally using ffmpeg, but i cant.This stream is a camera, and Ive tested the video stream in VLC. It works.
First, the ffplay command (ffplay rtsp://ip ) returns
[rtsp @ 0x7fa574009280] UDP timeout, retrying with TCP   0B f=0/0   
[rtsp @ 0x7fa574009280] method PAUSE failed: 455 Method Not Valid in This State
[rtsp @ 0x7fa574009280] Could not find codec parameters for stream 0 (Video: h264, none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options
Input #0, rtsp, from 'rtsp://ip':

So, i installed h264 and h265 codecs and re-installed ffmpeg. But the same error happened.Alsp, i tried the ffmpeg command
ffmpeg -i rtsp://ip -r 15 outvideo.mp4
the result is:
[rtsp @ 0x11e30c0] UDP timeout, retrying with TCP

I tried with several parameters I found on the web. No chances to work.

I think it is a codec problem, or maybe the reason is that my camera is in 192.168.32. and my computer works in 192.168.31.I am searching for suggests, reasons, commands .. Everything that helps..
