• Publishing an RTSP stream from my IP camera to a remote MediaMTX / RTSP Simple Server using FFmpeg and Azure [closed]

  28 janvier 2024, par cmd

  Using FFmpeg, I am trying to publish the RTSP stream from my IP camera to an Azure VM running a MediaMTX instance https://github.com/bluenviron/mediamtx. My intention is for the stream to be accessible from other remote connections by connecting to the VM.

  


  I was able to setup a local MediaMTX server on my laptopm, and publish the stream using this FFmpeg command :

  


  ffmpeg -i rtsp://<camera username="username">:<camera password="password">@<camera local="local" ip="ip">:554 -c:v copy -c:a copy -f rtsp rtsp://<laptop local="local" ip="ip">:8554/stream/mystream&#xA;</laptop></camera></camera></camera>

  


  This worked fine, as I was able to connect to the MediaMTX server in VLC player to view the stream. However, I have setup an Azure VM running Windows 10, and run the same MediaMTX instance on it. I have attempted to publish the RTSP stream from the IP camera using the same command, but with the Laptop IP replaced with the address of the VM, but this doesn't work.

  


  I have disabled the Windows Firewall on my laptop and the VM, but the stream can still not be published. I have also tried the same approach by running the MediaMTX server on my friend's computer on his network, and adding the necessary port forwarding rules to his router. I am unable to edit any rules on the router where I am living however.

  


  What else might be causing this issue, and is there any way to publish the IP camera's RTSP to a remote server where it could then be read ?

  


• flutter FFMPEG concat not working properly with camera recorded clips

  27 février 2024, par ibrahim Eltayfe

  I am using the Flutter camera package to record videos, I record multiple videos and then concatenate them using this command :

  


  


  "-y -f concat -i $videosPathsTextFilePath -c:a aac -c:v copy $fullVideoOutPath",

  


  videosPathsTextFilePath content is :
  
file 'record-1709022968582.mp4'
  
file 'record-1709022976601.mp4'

  


  


  when I record with one side only like the camera back side and concatenating the clips, it works as expected, but when I change the camera side and then concat the clips, the clip recorded after changing the camera side is shown rotated upside down as -90

  


  I checked the clips from Device Explorer, it is all right, but after the concatenation it shows flipped.

  


  here are the two videos before concatenation :

  and this is the video after concatenating :

  Thank you in advance.

  


  I tried to check if the user changed the camera side to track the clips recorded by this side then rotate them and move them to another directory but this command is not working

  


  -noautorotate -display_rotation 90 -i ${videoFile.path} -c:v copy ${destinationPath}

  


• Try to concatenate videos using FFmpeg Package. My videos concatenate correctly but those that i record from fornt camera rotate 90' in concatenate

  24 avril 2024, par Ahmad Akram

  Here is my code where I pass a list of image paths that concatenate. I am facing an issue with the front camera video. When concatenated completely some videos rotate 90 degrees.
