• FFMPEG not creating thumbnails

  12 juin 2016, par MixedVeg

  My ffmpeg command in php is

  echo $cmd_thumbnail_create = ("\"$ffmpeg\" -i \"" . $dir.$videopath . "\" -an -ss $getFromSecond \"" . $dir.$thumbnailpath ."\"");
  
  exec($cmd_thumbnail_create);

  Output of which is

  "C :\FFMPEG\bin\ffmpeg" -i "C :/xampp/htdocs/final/uploaded_videos/intro_en.mp4" -an -ss 6 "C :/xampp/htdocs/final/thumbnail/intro_en.jpg"

  This when copied and executed on the command prompt creates the thumbnail at proper location with proper name.

  Any suggestions ?

• Have 2 blocking scripts interact with each other in linux

  18 novembre 2014, par Ortixx

  I have 2 blocking shell scripts which I want to have interact with each other. The scripts in question are peerflix (nodejs script) and ffmpeg (a simple bash script).

  What happens : Peerflix fires up, feeds data to ffmpeg bash scrip which terminates peerflix on completion.

  So once peerflix starts it outputs 2 lines and blocks immediately :

  [08:15 PM]-[vagrant@packer-virtualbox-iso]-[/var/www/test]-[git master] 
  
  $ node /var/www/test/node/node_modules/peerflix/app.js /var/www/test/flexget/torrents/test.torrent -r -q
  
  listening: http://10.0.2.15:38339/
  
  process: 9601

  I have to feed the listening address to the ffmpeg bash script :

  #!/bin/sh
  
  ffmpeg -ss 00:05:00 -i {THE_LISTENING_PORT} -frames:v 1 out1.jpg
  
  ffmpeg -ss 00:10:00 -i {THE_LISTENING_PORT} -frames:v 1 out2.jpg

  After the bash script is done I have to kill the peerflix script (hence me outputting the PID).

  My question is how do I achieve this ?

• moviepy ffmpeg stderr to tkinter interface

  1er avril 2018, par Alexander Perlman

  Hi stackoverflow community,

  I’m a novice python hobbyist. I wrote a python / ffmpeg script using moviepy that batch concatenates videos. I then designed an interface using tkinter.

  Now I want to redirect the stderr output from FFMPEG to the tkinter interface so that users can review the progress directly in app instead of needing the Sublime text console.

  I’ve done a lot of research but I’m in way over my head. Any tips would be greatly appreciated.

  Here’s the moviepy component. The gui is pretty cut and dry

  #import video clips 
  
  mainvid = VideoFileClip(fullpath, audio=True)
  
  intro = VideoFileClip("intro.mp4", audio=True)
  
  black = VideoFileClip("black1s.mp4", audio=True)
  
  
  
  #concatenate video clips 
  
  final = concatenate_videoclips([black, intro, mainvid, black]) final.fps=24 
  
  
  
  #actually write file 
  
  final.write_videofile(output, audio=True, audio_fps=48000, ffmpeg_params=[ "-r","24000/1001", "-b:v", "50M", "-level:v", "4.1", "-c:a", "libvo_aacenc", "-b:a", "256K", "-colorspace", "bt709"])
