• Set ffmpeg path in supervsiorctl config file

  4 juin 2015, par interneteur

  I am having a issue where my code works fine when not under supervisor. But when under supervisor for some reason it is not finding the path to the ffmpeg dependency.

  (env)root@www:/home/www/yout# which ffmpeg
  
  /usr/bin/ffmpeg

  Is there any way to set the path to ffmpeg to have it check this ?

  Here is my config file

  [program:worker]
  
  directory=/home/www/yout
  
  environment=PATH="/home/www/env/bin"
  
  command=python worker.py high normal low
  
  process_name=%(program_name)s
  
  numprocs=1
  
  autostart=true
  
  autorestart=true
  
  stopsignal=TERM
  
  user=root
  
  stopsignal=TERM

• ffmpeg cut first 5 seconds

  25 mai 2015, par requiem31

  I am having trouble removing the first 5 seconds of a .mp4 video. Here is what I have so far :

  subprocess.call("ffmpeg -ss 00:00:00 -t 00:00:05 -i /home/requiem/Desktop/t1.mp4 -vcodec copy -acodec copy /home/requiem/Desktop/t2.mp4", shell=True)

  The issue is that it just takes the first 5 second and saves it, but I want the first 5 seconds removed and the rest saved. How would I do that, or can I find the duration of the video so I can set -ss 00:00:05 and -t DURATION

• Nginx Live transcoding with ffmpeg

  7 mars 2015, par Stian Tofte

  I’m live streaming video to my server(It’s external somewhere in the world).
  And what I’m trying to do here, is that my server will transcode the input to a lower bitrate before it pushes it to the video site like twitch and so on.

  And I’m doing this on windows. I have tried to google around watched youtube videos. and so on.. But couldn’t find any solution for it. So here is what I have at this moment(not working).

  In my nginx.conf :

  rtmp {
  
  server {
  
      listen 1935;
  
      chunk_size 8192;
  
  
  
      application code {
  
          live on;
  
  
  
      }
  
  
  
      application twitch {
  
          push rtmp://live-ams.twitch.tv/app/live_xxxxxxxxxxxxxxxxx;
  
      }
  
  }

  So here the application code is receving the stream from my computer at home. I’m using ffmpeg to transcode it.

  And here is my batch file(That I have to start manualy. Can’t start it within the config of nginx on windows.)

  ffmpeg -i rtmp://localhost/code -vcodec flv -acodec copy -s 1280x720 -f flv rtmp://localhost/twitch
  
  pause

  Right now It’s just downscaling but that is okay. So this is supposed to send the stream back to the "twitch" application in my nginx config. And then nginx will stream it to twitch.

  But when I launch my ffmpeg bat file.. I get this :
  

  So it’s here my road ends. Anyone knows how to do this ?

  Thanks in advance :) Stian
