• Video duration not detected by moviepy

  27 août 2023, par Kyv

  I have downloaded a video online, and wanted to add a background sound to it.
I followed this link :
Combining an audio file with video file in python
But, while reading the file

  


  my_clip = mpe.VideoFileClip('file.mp4')


  


  I get the error [mov,mp4,m4a,3gp,3g2,mj2 @ 00000152769e78c0] moov atom not found : path/to/file.mp4 Invalid data found when processing input from line 320 in the github resource https://github.com/victorcampos7/tensorflow-ffmpeg/blob/master/ffmpeg_reader.py
How to overcome this issue ?

• ffmpeg posting to nginx hangs after 90 minutes

  22 octobre 2018, par Harnek Gulati

  I’m using a very simple program to push an ffmpeg stream from my raspberry pi camera to a nginx server. However, it fails after 90 minutes, with almost every single Raspberry Pi I use (I have this code on 12 Raspberry Pis).
  Here is my ffmpeg command :

  raspivid -o - -t 0 -w 640 -h 480 -fps 25 | ffmpeg -re -i - -vcodec copy -hls_time 4 -f hls -hls_list_size 5 -hls_wrap 5 -threads 0  -timeout 5000 -max_reload 20000 -method PUT http://{}:{}/live/{}

  And here is my configuration for nginx.conf :

  #user nobody;
  
  load_module /usr/lib/nginx/modules/ndk_http_module.so;
  
  load_module /usr/lib/nginx/modules/ngx_http_lua_module.so;
  
  
  
  worker_processes auto;
  
  env CONTROL_SERVER_IP;
  
  
  
  
  
  #error_log /var/log/nginx/error.log;
  
  error_log /dev/stdout info;

      worker_connections 1024;

              client_body_temp_path   /var/static/client_temp;
  
  
  
              dav_methods PUT;
  
              create_full_put_path on;
  
              dav_access user:rw  group:r     all:r;
  
  
  
              types {
  
                  application/vnd.apple.mpegurl m3u8;
  
              }
  
  
  
              # Disable Cache
  
              add_header Cache-Control no-cache;
  
              include cors.conf;
  
    }
  
    }
  
  }
  
  
  
  daemon off;

  If anyone can help me, I would deeply appreciate it. I’ve been pulling my hair out trying to figure out this bug. On the raspberry pi, it hangs on this :

  And on the nginx logs, I get :

  I need to set up a way to either a) keep consistent connections longer than 90 minutes or b) detect when the 408 error happens and stop it from hanging.

• FFmpeg zoompan animation results in zig-zag pattern [closed]

  2 février 2024, par kregus

  please assist, as I am pulling my hair out !

  


  The goal is for a user to specify a zoomPoint in a video as follows :

  


  {
   "scale":4,        # Scale factor, here x4
   "offset":0,       # Start zooming in after 0ms
   "duration":5000,  # Stay zoomed in for 5000ms
   "marginX":80,     # Zoom x to 80% of video width 
   "marginY":10      # Zoom y to 10% of video height
}


  


  I am running the following, simplified FFmpeg command :

  


  ffmpeg -i "/tmp/input.mp4" -c:v libx264 -r 30 -vf "scale=iw*2:ih*2,zoompan=fps=30:z='if(gte(it,0.0)*lt(it,5.0), min(pzoom+0.2, 4),if(gte(it,5.0)*lt(it,5.5), max(pzoom-0.2, 1), 1))':d=1:s=1512x982:x='(iw - iw/4)*(80/100)':y='(ih - ih/4)*(10/100)'" /tmp/output.mp4


  


  The animation duration is 0.5s, the video framerate is 30fps, and so there are 0.5 / (1/30) = 15 animation frames.

  


  Zoom distance is scale - 1 = 3 in this case, which makes the zoom increment 3 / 15 = 0.2.

  


  This results in the following example video : click here

  


  While the zoom animation ends in the correct position, you will notice it arrives at that position in a zig-zag pattern, where it starts by zooming into the top-right corner, before changing direction towards the correct position.

  


  I cannot seem to figure out how to get it to animate the zoom in a straight line to the specified x/y position.

  


  Any tips are welcome, thanks !
