• Diagonal Split using ffmpeg

  8 juillet 2017, par Jeffin

  I am trying to acheive the following effect using ffmpeg

  

  I have tried multiple options , but failed so far,

  I have referred the following questions , not happening for me

  • FFmpeg : Add alpha channel to a video using a PNG mask
  • FFMPEG Crop with side by side merge
  • https://superuser.com/questions/916431/ffmpeg-filter-to-boxblur-and-greyscale-a-video-using-alpha-mask?rq=1

  I have three videos but i have somewhat acheived the diagonal split for two videos using the following code , but still couldnt get the output for three videos or four

  ffmpeg -i input0 -i input1 -filter_complex \
  
  "[1:v][0:v]blend=all_expr=if(gt(X\,Y*(W/H))\,A\,B)" output

• Streaming a video with serial port [on hold]

  23 août 2019, par kanki66

  I need an application which is streaming an video recorded by an webcam over the serial port in c#

  I opened an port and can send some data over the port. I have access to the webcam and have an picture/video on the screen. For the webcam part i used this tutorial :
  https://en.code-bude.net/2013/01/02/how-to-easily-record-from-a-webcam-in-c/

  void videoSource_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)
  
  {
  
    //Cast the frame as Bitmap object and don't forget to use ".Clone()" otherwise
  
    //you'll probably get access violation exceptions
  
    pictureBoxVideo.BackgroundImage = (Bitmap)eventArgs.Frame.Clone();
  
  }

  How can i convert now this to an video as small as possible and send it over the serial port, without saving the video like directly to the serial port ?

  Thank you very much for the help

• FFserver : Securing with HTTP Authentication ? (Apache ?)

  6 février 2012, par mdaddy

  Is there some way to secure an ffserver webcam stream using Apache / HTTP Authentication ? Some type of Apache proxy perhaps ?

  Right now I have it so only machines on the LAN can view the http://webcam/stream.mjpg, but I want people from the outside to be able to access it if they provide a username / pw (HTTP Auth, which isn't built into ffserver).

  Thanks !
