Configure NVR to accept video stream from IP camera routed through PC
11 juin 2021, par BenStackoverI currently have an IP camera connected to an ethernet port on my PC. I also have my PC connected to a network switch via another ethernet cable. I have a NVR connected to the same network switch. I would like to be able to access the video stream from the camera (that is connected to the PC) on the NVR. I have tried restreaming the camera feed using ffmpeg and udp :


ffmpeg -i 'rtsp://user:pwd@192.168.xxx.xxx:554' -preset ultrafast -tune zerolatency -codec:v libx264 -f mpegts udp://admin:admin@192.168.yyy.yyy:8090


where the xxx.xxx is my PC and yyy.yyy is the NVR however the NVR cannot connect. If I connect another PC to the same network switch and change yyy.yyy to that PC's IP I can view the stream.


I have also tried setting up ffserver as an rtsp server using ffserver and can view the rtsp stream from the first PC on the second PC using
ffplay rtsp://192.168.xxx.xxx/test1.sdp
on the second PC after launching the server on the first PC. I cannot connect to the same stream from the NVR.

Can anyone tell me if what I am attempting to do is even possible ? Ie. how can I make my NVR see a video stream that isn't directly from an IP camera ?


Any help would be much appreciated.


Thanks !

How to prevent ffmpeg from crashing if UDP target is unreachable
17 décembre 2014, par sg90I am using ffmpeg to capture an input video feed from a capture device, save to disk, and relay the feed via udp to a host machine. When the network is down, i.e. an unplugged cable, or faulty switch, or the host is down, ffmpeg crashes with :
[mpeg1video @ 0x2fdcb20] ignoring invalid SAR: 0/0
Last message repeated 38 times
av_interleaved_write_frame(): Network is unreachable
frame= 758 fps= 25 q=1.0 size= 616kB time=00:00:30.24 bitrate= 166.7kbits/sframe= 758 fps= 25 q=1.0 Lsize= 616kB time=00:00:30.24 bitrate= 166.7kbits/s<br />
video:616kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.000000%
Conversion failed!When the network crashes, this also crashes the saving to disk. Unfortunately my capture device cannot handle multiple simultaneous access so I can’t split this into two processes (easily).
I would like to make the UDP streaming fault tolerant to continue trying to stream the next frame if it can’t send any packets. As UDP is "fire and forget", I am quite surprised this already isn’t the default behaviour - I’d even expect HTTP streaming to do the same without crashing. Surely this has happened to other ffmpeg users ?
Is there a flag I can set to continue/ignore the "Network is unreachable" exception thrown ?
I’d like to do this without making a custom build of ffmpeg, but if anyone has tried this before I would appreciate any pointers.
Thanks
