• How can I increase the performance of this video watermarking call which seems to be only using 6% of my system's CPU ? Currently using ffmpeg

  24 août 2023, par Codemonkey

  I have a php script to add a watermark to an uploaded video, using ffmpeg

  


  shell_exec("ffmpeg -y -i input.mp4 -i watermark.png -filter_complex $filter output.mp4")


  


  The video is 36 seconds long, 33MB and 1080x1920, 24fps. The output video comes in at 8MB, scaled down to 540x960 with a PNG overlaid as a watermark.

  


  The script takes about 3 seconds, averaging 320fps or so. For a one-off this would be ok, but I'm going to be processing hundreds/thousands of these at a time.

  


  I have 128GB of ram and an EPYC 7502p (32cores/64threads), and both input and output files are on NVMe drives.

  


  If I monitor top showing all my cores/threads in another window, with refresh delay set to a variety of things from 0.1 to 2 seconds, I'd guesstimate that this hits about 1/4 of my available threads, at about 25% utilisation each.

  


  So it kind of feels like I COULD see a 16x speed increase if it hit all of them at 100%. That actually wouldn't be ideal, locking up the server of course, but when my CPU is sat at 99% idle 99% of the time, I feel it could do better - it'd be nice to see it hitting at least half the cores or utilising at least 50% of them when it does...

  


  So, is there anything I can change with ffmpeg's config/build or the way I call it ? If this is as good as ffmpeg can do, are there better tools for the job ?

  


  Thank you

  EDIT :

  


  A few things I've learnt since posting :

  


  

  • -c:v libx264 -preset ultrafast - marginal help

  


  • nice -n -10 - marginal help (changing to -20 is makes negligible difference)

  


  • -c:a copy - significant help, which I found surprising

  


  


  FPS up from 320 to 540 using those 3 combined. I still feel there should be significantly more gains somewhere though...

  Here's the output from the original script, if it helps :

• Programmatically Streaming with ffmpeg library using linux system video device

  21 novembre 2019, par zafer sevim

  I am able to stream a static mp4 file coded with h264 in my code.

  But when I use linux video device /dev/video0 as input in my program, it gives this error :

  failed to open file `udp://xxx.xxx.xxx.xxx:28000` or configure filtergraph.

  I’m not using an encoder in my program yet. I don’t understand why I can’t stream directly from the video camera.

  The static mp4 file is encoded in h264. My code streaming is it as it is, but when I try to stream the camera with the video4linux2 format, it does not play.

  Do I need to encode the camera’s output with any format ?

• Add black video to video with sound

  4 février 2017, par garrettlynch

  I’m trying to insert 13 seconds of black video at the start of a video that has sound using ffmpeg like so :

  ffmpeg -f lavfi -i "color=c=black:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
  
  "[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
  
  [blackstart] [1:v] concat=n=2:v=1:a=0[out]" \
  
   -map "[out]" -c:a copy output.mp4

  However the sound is not being maintained. What am I doing incorrectly ? -c:a copy does not seem to work should I be using a [1:a] somewhere ?

  garrett-retina:~ garrett-macbookretina$ ffmpeg -f lavfi -i "color=c=red:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
  
  > "[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
  
  > [blackstart] [1:v] concat=n=2:v=1:a=0[out]" \
  
  >  -map "[out]" -c:a copy output.mp4
