  PHPVideoToolkit Error: Execute error. Output for file "C:\xampp\htdocs\phpvideo\examples\working\tmp\1336156630-4fa421d69357d\tmp_%d.jpg" was not found. Please check server write permissions and/or available codecs compiled with FFmpeg. You can check the encode decode availability by inspecting the output array from PHPVideoToolkit::getFFmpegInfo().

  i m trying to make it work since last many hours but no luck

  Also, for this code :

  $srcFile = "test-mpeg.mpg";
  
  $ffmpegObj = new ffmpeg_movie($srcFile);

  i am gettign error that it cant file the file. i believe its something to do with permissions but i m not able to figure out

  fpoen , fwrite , file_put_contents all are working fine without any permissions problems.

  can anyone please guide me in the write direction. what do i need to do to make this phpvideotoolkit work

• What happens when I use too much RAM from spawning process with Popen in Python ? [closed]

  2 février 2020, par lms702

  I have a Python script that is rendering a video with FFmpeg where I have all the images and audio I need. I am currently invoking FFmpeg via multiprocessing.Popen, which works very quickly on my computer but the Task Manager shows that I am using 12 GB of RAM while doing so (since there end up being 100s of instances of FFmpeg.exe running). I want to deploy this on a linux server one day with much less RAM, but I worry that I’ll run into problems with my approach. Does Python/the OS handle this or should I limit the number of processes I spawn myself ?
