• Streaming live video with avconv/ffmped on nginx rtmp server player error

  6 juin 2014, par user3715403

  Good morning,
  My current project involves playing live video (testing using a usb webcam for now). I compiled and installed nginx server with the rtmp module (obtained from https://github.com/arut/nginx-rtmp-module). The nginx configuration file is as :

  worker_processes  1;
  
  
  
  error_log  logs/error.log debug;
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  rtmp {
  
      server {
  
          listen 1935;
  
  
  
          application myapp {
  
              live on;
  
  
  
              #record keyframes;
  
              #record_path /tmp;
  
              #record_max_size 128K;
  
              #record_interval 30s;
  
              #record_suffix .this.is.flv;
  
  
  
              #on_publish http://localhost:8080/publish;
  
              #on_play http://localhost:8080/play;
  
              #on_record_done http://localhost:8080/record_done;
  
          }
  
      }
  
  }
  
  
  
  http {
  
      server {
  
          listen      8080;
  
  
  
          location /stat {
  
              rtmp_stat all;
  
              rtmp_stat_stylesheet stat.xsl;
  
          }
  
  
  
          location /stat.xsl {
  
              root /path/to/nginx-rtmp-module/;
  
          }
  
  
  
          location /control {
  
              rtmp_control all;
  
          }
  
  
  
          #location /publish {
  
          #    return 201;
  
          #}
  
  
  
          #location /play {
  
          #    return 202;
  
          #}
  
  
  
          #location /record_done {
  
          #    return 203;
  
          #}
  
  
  
          location /rtmp-publisher {
  
              root /path/to/nginx-rtmp-module/test;
  
          }
  
  
  
          location / {
  
              root /path/to/nginx-rtmp-module/test/www;
  
          }
  
      }
  
  }

  The command line to start streaming is as :

  avconv -s vga -f video4linux2 -i /dev/video0 -vcodec libx264 -an -f flv -b 800k -r 30 rtmp://localhost/myapp/live

  While streaming, the following stats are displayed :

  Any suggestions about what would cause the errors displayed by VLC/avplay ?

• FFMpeg frame drop when merging a image sequence and overlaying during video creation process

  29 juillet 2018, par Killer

  I have reviewed both the answer as mentioned in Similar Issue But still, I am having some frame drops.

  Here is what I was doing :
  Question 1
  Question 2

  Currently, I am showing a few images (one after another each with
  duration ’x’) on a sample background along with a music playing in the
  background.

  This is the command I am using to get the desired functionality :

  ffmpeg 
  
  -hide_banner 
  
  -y 
  
  -loop 1 
  
  -r 1 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_WEDDING_FRAME.png 
  
  -r 1/4 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_SELECTED_IMAGE_%d.png 
  
  -filter_complex overlay=(W-w)/2:(H-h)/2,drawtext=text=WedMojo:fontcolor=white:fontfile=/data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Files/FONT_WED_MOJO_WEDDING.ttf:fontsize=30:x=w-tw-20:y=h-th-20 
  
  -c:v libx264 
  
  -profile:v high 
  
  -crf 17 -pix_fmt yuv420p 
  
  -preset ultrafast 
  
  -t 16 -strict experimental 
  
  -r 24 
  
  /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Videos/VID_WED_MOJO_WEDDING_OUTPUT.mp4

  note : -r 1/4 for each image to be shown for 4 sec.

  I have checked the format of the images. All are the same. Also on changing preset and other values, the problem seems to be same. Log states drop=0, however, there are gaps as the overlay image is removed in between.

  Video sample with the duration set to 4 i.e each image to be set for 4 seconds.

  -> -> Video Output with 4 sec duration for each image

  However, there are no frame drops when the duration set to 1 or 2.

  -> -> Video Output with 2 sec duration for each image, ignore zoompan

  Log details :

• Ffmpeg concat images doesn't finish all images

  18 septembre 2015, par Simon

  I’m trying to do a simple task with ffmpeg. I’ve pre-generated about 100 png images (all same resolution) and separetely generated a list of them to be used by ffmpeg to concat them into a video. Each frame is likely to be used more than once. The output video is to be about 10,000 frames.

  The problem is that ffmpeg stops at about frame 4000 with no error. The final video works with no error.

  ffmpeg command :

  ffmpeg  -f concat -i frame_list.txt -vf fps=10 output.mov

  frame_list.txt sample :

      file 'frame_0045.png'
  
      file 'frame_0046.png'
  
      file 'frame_0047.png'
  
      file 'frame_0046.png'
  
      file 'frame_0047.png'
