• High CPU Usage with FFMPEG [closed]

  4 septembre 2021, par AlanPear

  I am trying to stream to Youtube Live using FFMPEG, and it works well for about a minute.

  


  After a minute all the cores on my machine (tired both 2 and 4 cores) run at 100% and the stream freezes. Here is the command I am running :

  


  ffmpeg -loglevel error -re -filter_complex movie=/home/kyle/Documents/myStream/video/FrighteningSparklingHomalocephale.mp4:loop=0,setpts=N/FRAME_RATE/TB -i /home/kyle/Documents/myStream/audio/Aviscerall-Just Livin-05Unhappy.mp3 -codec:v libx264 -pix_fmt yuv420p -preset ultrafast -b:v 800k -r 30.0 -g 60.0 -codec:a aac -b:a 128k -ar 44100 -maxrate 800k -bufsize 400k -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/somekeyhere


  


  Any ideas as to what I am doing wrong ?

  


• ffmpeg is not running from php exec() function, work from command line

  6 mars 2016, par Thanigaivelan

  When i run the ffmpeg command it is working from command line. but when i try from php exec(). it returns 127 error.

  my ffmpeg

  root@w1 [/]# which ffmpeg
  
  /root/bin/ffmpeg

  this is my code

  ffmpeg-y -i /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig.mp4 -acodec libfdk_aac -ab 24k -ar 44100 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 31 -b:v 200k -g 72 -f hls -hls_time 3 -hls_list_size 999 -s 426x240 /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig-240-index.m3u8
  
  
  
  when i run this code in from command line it work fine. but when try to run from php exec i am getting failed, it returns 127.

  i had tried like this also

  /path/to/ffmpeg-y -i /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig.mp4 -acodec libfdk_aac -ab 24k -ar 44100 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 31 -b:v 200k -g 72 -f hls -hls_time 3 -hls_list_size 999 -s 426x240 /home/castbox/public_html/IGVideo/upload/tamil/videos/testing/test_ig-240-index.m3u8

  Where is my mistake ?

• FFmpeg file path exception like file name not found

  7 février 2018, par Sagar Hudge

  I am getting following exception on video trimming.

  video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

  file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

  and ffmpeg searching for only Fast in

  /storage/emulated/0/Pictures/Instagram/Fast: No such file or directory

  I have found the issue ,it is causing due to the file name having spaces in between them you can check in above mentioned path and in exception.

  after changing file name its working but changing name of every file from device its not the right way so how can I solve this exception
