• How to make ffmpeg delete the original file after changing containers ? (using a send to bat file)

  12 mars 2020, par Bloggy

  I’m currently using a bat file in my shell:sendto folder that allows me to right click MKV files and open a cmd window that uses ffmpeg to change containers and produces an mp4 in the same directory as the source file. It works great, but I’d like to automate the process of deleting the original MKVs after (successfully) changing containers, and skipping the recycle bin if possible.

  Right now my .bat file is like follows :

  "C:\ffmpeg\bin\ffmpeg.exe" -i %1 -codec copy "%~n1.mp4"

  I’ve looked it up already but could only find a similar question about batch processing an entire folder and without the sendto part, and I wasn’t sure how to make that work for me.
  So if someone could point me towards what to append to it to make it happpen, I’d appreciate it.

  Thanks ! :)

• Starting and stopping an ffmpeg pipeline in python

  25 septembre 2014, par user3147697

  I’m trying to start and stop an ffmpeg pipeline in my Python script. I can get it to start the pipeline on command, using a subprocess, but it ties up the script, so that it no longer receives commands. What do I need to change to keep this from happening ?

  I’m using :

      pipeline= "ffmpeg -f video4linux2 -video_size 640x480 -framerate 15 -input_format yuyv422 -i /dev/video7 -f alsa  -i hw:0,0 -map 0:0 -map 1:0  -b:v 120k -bufsize 120k -vcodec libx264 -preset ultrafast  -acodec aac -strict -2  -f flv -metadata streamName=myStream tcp://192.168.1.20:6666 "
  
  
  
      p = subprocess.Popen(pipeline, shell=True,
  
                           stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
  
      output = p.communicate()[0]

• How to use random name for image file generated using ffmpeg-php ?

  13 octobre 2017, par Brains Akd

  The image is generating fine with the below code

  $thumbnail = 'images/thumbnail.jpg';
  
  
  
  // shell command [highly simplified, please don't run it plain on your script!]
  
  
  
  shell_exec("ffmpeg -i $video -deinterlace -an -ss 1 -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg $thumbnail 2>&1");

  But it creates a file named thumbnail.jpg
  I need to have random name for images generated to save it in the images folder and database. How can i generate a random name to thumbnail in the below code
  $thumbnail = 'images/thumbnail.jpg';
