• 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 ?

• How to encode (ffmpeg x264) with continuous seek

  13 avril 2015, par CV_User

  I have a batch file that encodes video files from ’Source’ folder to ’Target’ folder.

  The batch file content is :

  for %%a in ("Source*.*") do @echo DirectShowSource("%%a") >> "batchScript.avs" && @echo MSharpen(10,120) >> "batchScript.avs" && ffmpeg -i "batchScript.avs" -n -c:v libx264 -crf 24 -c:a libmp3lame -b:a 192k "Target\%% na.mp4" && del "batchScript.avs" pause

  I’m not sure why, but when I playback the encoded files in media player classic I can only jump to discrete jumps in time and not to the exact time I clicked on.

  What can be done so this doesn’t happen ?

  Thanks all !
