• Processing 3.0 get Error=2 No such file or directory

  29 octobre 2016, par Tuang Pingfavilunda

  I cannot figure it out what happen to my Processing file. I am trying to use VideoExport library and my Macbook Pro cannot play it, but the Mac-mini is able to do so.

  Before the error happened it is another error=13 permission denied thing, so I messed in the terminal for a while with chmod 777 and finding the file with ls. I don’t know if that may be the reason that caused this happen. FYI, I also installed ffmpeg already.

  And this is the full error :

      java.io.IOException: Cannot run program "/Users/Tuang/Desktop/DMA_WORKS/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde": error=2, No such file or directory

  1) The java.io.IOException : trying to call "/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde" which doesn’t exist for real. It is gone for a long time but seems like the program stuck here.

  2) "basic" is a file name from the Example of the Library. I just use it to test. Surprisingly, Every files that have been saved and changed the name still get the java.io.IOException’s error of the missing sketch_161027a.pde file.

  What I have done :
  1 I have already done the Homebrew thing to install ffmpeg.
  2 I deleted everything of Processing and reinstall it again.

  Any suggestion ?

• ffplay : do not preallocate video texture

  ffplay : do not preallocate video texture
  Since the uploads happen in the main display function, it does not matter much.

• Python OpenCV real-time blurring with saving to output

  10 janvier 2024, par Oleg Novosad

  I have a live video stream via RTSP from my IP camera. I want to blur faces on that stream and output for mobile usage (HLS, H.264, etc). All this should ideally happen in real-time — with the minimum of resources consumed. I plan to deploy this later to some cloud, so the less money I spend on resources the better.

  


  Currently I have a working solution like so :

  


  

  • I capture video using OpenCV

  


  • I update every frame with Gaussian Blur and save it to some folder

  


  • After some amount of frames I create MP4 / AVI / whatever video and make it accessible via HTTP URL

  


  • All of it is running on Django for now

  


  


  I know I am doing something wrong, can someone suggest a better solution ?
