• 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

• Play AAC in SoundManager2 won't start

  27 novembre 2012, par sasa

  I converted audio file MP4 to AAC and then want to play that file in SoundManager2. If I use some software for Windows for convert, everying is fine, audio is playing well. But, on server side when MP4 file is converted to AAC using ffmpeg, file is loaded in SM2, but playing is not started.

  I use this command :

  ffmpeg -i in.mp4 out.aac

  Here is SoundManager2 log :

• How to not add AdaptationSet for audio in cmd file if audio stream is not present in input video file

  15 juin 2019, par Saurabh

  I am using ffmpeg-dash to create mpd files. I am using following command to generate the same :

  ffmpeg -i input/video.mov \
  
          -map 0:v:0 -map 0:v:0 -map 0:v:0 -map 0:a\?:0 \
  
          -b:v:0 350k -c:v:0 libx264 -filter:v:0 "scale=320:-1" \
  
          -b:v:1 1000k -c:v:1 libx264 -filter:v:1 "scale=640:-1" \
  
          -b:v:2 3000k -c:v:2 libx264 -filter:v:2 "scale=1280:-1" \
  
          -use_timeline 1 -use_template 1 -window_size 6  -adaptation_sets "id=0,streams=v id=1,streams=a"  \
  
          -seg_duration 2 -threads 16 -hls_playlist true -f dash output/ffmpeg/output.mpd

  This works with video which has audio streams, but for the case there is no audio stream in the video file, I get empty entry for audio in mpd files like following, which is not valid and fails while playing in Exo Player in Android.

  <adaptationset contenttype="audio" segmentalignment="true" bitstreamswitching="true">
  
  </adaptationset>

  I tried adding ? in option adaptation_sets like : id=0,streams=v id=1,streams=a?, however that also adds above line.

  One solution is to run different commands for different videos by first checking whether there is audio stream or not, but would be better if there is some option which add audio adaptationSet only if audio stream is present in the input file.
