Hi. With this command line I can capture the video stream from my personal onvif camera using my linux machine and the official already built ffmpeg executable from the ffmpeg website. *./ffmpeg -i rtsp://192.168.1.162:554/onvif1 a.avi*
But I can't capture the video stream from another onvif camera, the command line is *./ffmpeg -i rtsp://admin:admin@172.30.153.33:554/1 a.avi* The ffmpeg output is denis@tomcat:~/Scaricati/ffmpeg-3.4.2-64bit-static$ ./ffmpeg -i rtsp:// admin:admin@172.30.153.33:554/1 a.avi ffmpeg version 3.4.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2018 the FFmpeg developers built with gcc 6.3.0 (Debian 6.3.0-18) 20170516 [rtsp @ 0x43a4bc0] UDP timeout, retrying with TCP [rtsp @ 0x43a4bc0] method PAUSE failed: 455 Method Not Valid In This State [rtsp @ 0x43a4bc0] Could not find codec parameters for stream 0 (Video: h264, none): unspecified size *Consider increasing the value for the 'analyzeduration' and 'probesize' options* Guessed Channel Layout for Input Stream #0.1 : mono Input #0, rtsp, from 'rtsp://admin:admin@172.30.153.33:554/1': Metadata: title : h264.mp4 Duration: N/A, bitrate: 64 kb/s Stream #0:0: Video: h264, *none*, 90k tbr, 90k tbn, 180k tbc Stream #0:1: Audio: pcm_mulaw, 8000 Hz, mono, s16, 64 kb/s Stream mapping: Stream #0:1 -> #0:0 (pcm_mulaw (native) -> mp3 (libmp3lame)) Press [q] to stop, [?] for help [rtsp @ 0x43a4bc0] UDP timeout, retrying with TCP [rtsp @ 0x43a4bc0] method PAUSE failed: 455 Method Not Valid In This State rtsp://admin:admin@172.30.153.33:554/1: Operation not permitted Finishing stream 0:0 without any data written to it.

Can someone suggest me how to resolve? Is ffmpeg not fully compatible with all video cameras?
