• node-rtsp-stream stop streaming after some time

  12 mai 2020, par Vishal Patel

  I am using node-rtsp-stream to display live camera streaming in web application. It's work fine but after sometime it stop streaming and display following error :

  



  1|streamca | [h264 @ 0x560869d8f380] 
1|streamca | error while decoding MB 145 65, bytestream -16
1|streamca | [h264 @ 0x560869d8f380] concealing 3904 DC, 3904 AC, 3904 MV errors in I frame
1|streamca | rtsp://username:password@ipAddress/Streaming/Channels/1: corrupt decoded frame in stream 0


  



  What is going wrong ?
My code looks like :

  



  const Stream2 = require('node-rtsp-stream');
let stream2 = new Stream2({
  name: 'name',
  streamUrl: 'rtsp://username:password@ipAddress/Streaming/Channels/1',
  wsPort: 88,
  ffmpegOptions:{
    '-stats': '',
    '-r': 22,
    '-q:v': 50
  }


  



  })

  


• Get rtsp udp streaming with ffmpeg utility failed

  16 février 2021, par Lidor Abo

  Hey there,
I have a problem with get streaming from wowza stream engine as described below :
I try to get streaming in private network from wowza stream engine in UDP with ffmpeg as following :
ffmpeg -loglevel debug -rtsp_transport udp -i "rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream" -acodec copy -vcodec copy test.mp4
and i get the following error :
rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream : Connection timed out
Few remarks about that :

  


  

  1. When i try to get streaming using public ip with ffmpeg utility i success in UDP and TCP

  


  2. I success to get streaming with private IP with TCP connection through ffmpeg utility as following :
ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream" -acodec copy -vcodec copy test.mp4

  


  3. I open 1935 UDP and TCP ports in security group of wowza stream engine for machines that will need to get streaming from wowza stream engine. Also, i opened UDP in 6970-9999 range for any ip address.

  


  4. I added relevant IP address in Whitelist property in Server.xml conf in wowza stream engine.

  


  5. I using vpn service (perimeter) to access the machine that from it i get streaming from wowza streaming engine.

  


  6. iptables in machine that i try to get stream allow any rule and not enabled any firewall.
Note : i adding link to zip file with logs and config files because is not me your upload limitations :

  


  


• Convert asset to fMP4 in device (iOS) for streaming

  1er février 2018, par GustavoAzOl

  I have a local asset, recorded by the user, and I want to export a fMP4 to be upload to the server and later be used for streaming. I’ll target iOS 10.0 and later and use swift.

  How can I do that locally on the device ? Is there a "native" way or even a better way to do that ?
  I saw some people using ffmpeg but it seems a bit more complex to get it work on the project.
