• Processing3 get "Error=2 No such file or directory" with a file that actually doesn't exist at the first place

  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 ?

• ffmpeg same input as output file (temporary file needed but how ?)

  7 janvier 2021, par tomato planet

  I don't know much about .bat files or ffmpeg and spent the last hour on the internet searching how I can solve my problem, but didn't find anything.
I want to make .bat file which removes the audio of a video and replaces it with the no-audio version. I already made a folder with my .bat file and ffmpeg and added an option to the context menu to open my .bat file.

  


  That's my .bat file currently :

  


  ffmpeg -i %1 -an -vcodec copy %1


  


  But ffmpeg can't overwrite the file it's currently reading. It would be great if somebody helps me how to create a temporary file without the audio, and then replace the input file with the temporary one.

  


  Thanks a lot in advance !
