• better way to record desktop via ffmpeg

  29 mars 2014, par Maged E William

  in my form there's a timer that capture the screen as jpeg every 85 ms, it captures until the user shutdown the windows or electricity cut off so the last frame(image) may get corrupt which is okay for me, now when the user log in the form run on the start up now on the on load event it ask if there images in temp folder if yes it open ffmpeg to convert all images into one video but that seems to take a lot of time i have +300000 image and that because it capture the screen for at least a 10 hour every day but that will take a lot of time to convert them, i wonder if there any other way to directly record at a video and when electricity cut off that video file stay good with no corruption and with that i mean :
  i can't scroll or navigate
  

  here is my ffmpeg command : -f image2 -framerate 10 -i C:\\Temp\\%06d.jpeg -c:v libx264 -r 10 -crf 37 -pix_fmt yuv420p C:Video\\" + s + ".mp4

• Real time stereo video stream. How to start

  29 juin 2015, par victor jung

  Here is my problem :

  I have at one side two webcams plugged in a linux computer, and on the other side, an android smartphone. My goal is to program a real time stream of the 2 webcams, and display that stream on the smartphone (to be used in a google cardboard mask). I read quite a lot on the subject, and I found several way to achieve this.

  First there is ffmpeg, which could encode and stream.

  But I need to modify the pictures at some point, to re-size them / or to ad some kind of distortion. So I thought it would be great if I can get the 2 images, with openCv maybe, playwith them, build a new one, and stream them, but how could ffmpeg deal with the newly created image ?

  The other option would be to get the 2 pics and play with them with openCv too, but then, hardcode a stream over, UDP in RTP style, but wouldnt be hard to display the stream nicely on the phone ?, and how to cut the image to fit in small packets ?

  Thanks for your help, I am still digging in the subject, so if you have any other way to do it I am taking !

  Add coverity model file
  The comments/header of the file are taken from qemu, they provide some
  
  basic documentation
  
  The code from the examples
  Ive no means to test this except uploading to coverity for FFmpeg, so each
  
  commit should stay simple, making it easy to revert.
  Also please help making this a useful and effective file by contributing
  
  changes/code to it and reviewing contributions.
  
  I am happy to upload changes but i cannot really maintain this (alone) as
  
  i cannot test changes.
