Raspberry Pi cannot connect to IP camera, while Windows PC can ?
28 novembre 2020, par gf000I have an IP camera (Provision ISR, DI-320IPS-VF, 2MP IR Vari-Focal Dome IP Camera). When I connect it to my router (it is a 10 or 12 years old TP-LINK TL-WR1043ND), it will immediately show up in "IP Manager" (this is a program by the manufacturer) on my Windows PC. If I double click on the camera's row, Internet Explorer opens up, and everything is working fine. On the same Windows PC, if I open VLC Media Player, and paste this URL : rtsp ://username:password@localipaddress:554/profile1
It works fine.


I have also a "Raspberry Pi 4 model B 4 GB RAM", which is connected to the same router. If I open VLC Media Player, and I paste the same URL, it doesn't work. I also created an ffmpeg one-liner, which would take a photo, but that is also not working.


My final goal would be to be able to take photos with that ffmpeg one-liner, on the Raspberry Pi.


Maybe the Raspberry Pi is not powerful enough to handle the stream ? Or, could it be the problem that the IP-camera is sending H-264 / H-265 video stream, and the Raspberry Pi cannot handle it ?


Thank you for your help. Any idea could help me.

couldn't populate thumbnail on client side
8 novembre 2020, par Lokirouter.post("/thumbnail",(req,res)=>{

 let thumbsFilePath="";
 let fileDuration="";



 ffmpeg.ffprobe(req.body.filePath, function(err,metadata){
 console.dir(metadata);
 console.log('METADATA==>'+metadata);
 console.log(metadata.format.duration);

 fileDuration=metadata.format.duration;

 })

the screenshots are saved perfectly and their path is also received to the client-side from
thumbsFilePathbut I cant populate it in the client-side page(react).. idk what I am doing wrong here.

here is client-side code. I used
usestate

const [FilePath, setFilePath]= useState('');
 const [Duration, setDuration] = useState('');
 const [Thumbnail, setThumbnail] = useState('');


here is an error when I try to populate img




const onDrop=(files)=>{
 let formData= new FormData();

 formData.append("file",files[0])

Unable to record mediasoup producer using FFmpeg on real server
30 novembre 2020, par Sarvesh PatilI have built a nice app in react native for audio calling, many thanks to MediaSoup !!


To take it to next level, I need to record some of my calls.
I used this tutorial for reference :
mediasoup recording demo


I followed the FFmpeg way and have reached a point where I have created a plainTransport with


router.createPlainTransport({
 // No RTP will be received from the remote side
 comedia: false,
 // FFmpeg and GStreamer don't support RTP/RTCP multiplexing ("a=rtcp-mux" in SDP)
 rtcpMux: false,
 listenIp: {ip:"0.0.0.0", announcedIp:"MY_PUBLIC_IP"},
 });



Then I connect to this transport :


rtpPlainTransport.connect({
 ip: 127.0.0.1,
 port: "port1",
 rtcpPort: "port2",
 });



My first doubt : is the ip address in .connect({}) parameters supplied above correct ?


Second, the FFMPEG command requires an SDP header. This is mine :


v=0
 o=- 0 0 IN IP4 127.0.0.1
 s=-
 c=IN IP4 127.0.0.1
 t=0 0
 m=audio port1 RTP/AVPF 111
 a=rtcp:port2
 a=rtpmap:111 opus/48000/2
 a=fmtp:111 minptime=10;useinbandfec=1


When I start recording, the FFMPEG process does not receive any data.
Moreover, on stopping, I get the following message




Output file is empty, nothing was encoded (check -ss / -t / -frames
parameters if used) Exiting normally, received signal 2. Recording
process exit, code : 255, signal : null




I was able to make the recording save on localhost with 127.0.0.1 when the server was itself running on localhost.


However, with my actual server hosted with Nginx, I'm not able to figure out what is going wrong.


I can see data being sent on my audio port :


1 0.000000000 127.0.0.1 → 127.0.0.1 UDP 117 10183 → 5004 Len=75
2 0.020787740 127.0.0.1 → 127.0.0.1 UDP 108 10183 → 5004 Len=66
3 0.043201757 127.0.0.1 → 127.0.0.1 UDP 118 10183 → 5004 Len=76


What do I do with FFmpeg so that it starts the recording !?


Can someone please help ?
