• WriteToUDP only works on local machine

  26 mai 2017, par Anderson Scouto da Silva

  This script captures a flow entry by ffmpeg and writes to a UDP address.

  The error is that it does not go to the internet, it only stays on the local machine.

  It is not a problem in my internet network, because I made a stream through VLC and opened in another PC and it works normally, with the same parameters, but in this my script is only in the local PC.

  Follow the pictures to help with the question :

• Writing an image to linux framebuffer distorts the image C++

  8 avril 2021, par max

  Im trying to set up rtsp video stream from teledyne Dalsa Genie Nano camera. For grab images I'm using a framework provided by this company.
For rtsp stream I will use ffmpeg tool that can stream video directly from linux frame buffer.
  
So i tried to write this image via memcpy function and at this moment the image is not recorded correctly. because when i try to take a screenshot from Facebook with ffmpeg in output i have corrupted image.
  
Here's some information :

In the framework I have an image object that contains :

  


  

  1. void *address (address of one frame)

  


  2. int width (1280)

  


  3. int height (1024)

  


  4. int depth (1)

  


  


  So I wrote a function :


  


  It's working fine without any errors but when I print image from frame buffer (fb) I have

  


  

  


  I think it happens because fb device depth is 32 but frame depth is 1.

  


  Am I right ?

  


  I tried to change fb device depth with fbset tool but it returns an error -


  


  Command I use for taking an image from fb : sudo ffmpeg -f fbdev -framerate 1 -i /dev/fb0 -frames:v 1 screenAA3.jpeg

  


  Can someone tell me what I'm doing wrong ?
