• How to enable site on ngnix to restream

  19 mars 2020, par Nk nk nk

  i use rtmp+nginx to restream the channels with ffmpeg.

  The streaming is enabled for subdomain for example [hls.tvoti.com][1] but not for the main domain [tvoti.com][1]

  In Nginx site-enabled path i have mentioned that the main domain must be enabled but it doesn’t stream. Here is the config :

  server {
  
      listen   80; 
  
  
  
      #root /var/www/html/; 
  
      #index index.php index.html index.htm;
  
  
  
      server_name tvoti.com; 
  
  
  
      location / {
  
      proxy_redirect off; 
  
          proxy_set_header X-Real-IP  $remote_addr;
  
          proxy_set_header X-Forwarded-For $remote_addr;
  
      proxy_set_header X-Forwarded-Proto $scheme;
  
          proxy_set_header Host $host;
  
          proxy_pass http://127.0.0.1:8080;
  
      }
  
  
  
      location ~ /\.ht {
  
          deny all;
  
      }
  
  }
  
  
  
  server {
  
      listen       80;
  
      server_name  hls.tvoti.com;
  
  
  
      location / {
  
          add_header Cache-Control no-cache;
  
  
  
          # Simple requests
  
          if ($request_method ~* "(GET|POST)") {
  
              add_header "Access-Control-Allow-Origin"  "http://tvoti.com";
  
          }
  
  
  
          # Preflighted requests
  
          if ($request_method = OPTIONS ) {
  
              add_header "Access-Control-Allow-Origin"  "http://tvoti.com";
  
              add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
  
              add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
  
              return 200;
  
          }
  
          root   /etc/nginx/hls;
  
      }
  
  
  
      location /supervisor {
  
          proxy_pass http://127.0.0.1:9999/;
  
      }
  
  
  
      #error_page  404              /404.html;
  
  
  
      # redirect server error pages to the static page /50x.html
  
      #
  
      error_page   500 502 503 504  /50x.html;
  
      location = /50x.html {
  
          root   html;
  
      }

• ffmpeg - why I have three video streams in the output file when I have one video input (one video stream), one logo input

  17 juillet 2024, par Yazhou

  Hi I'm using ffmpeg to transcode some video files from prores or dv to h264/mov. Also I want to add a logo on it and make some other changes.
The command line I use is

  


  ffmpeg -i input.mov -i logo.png -c:a aac -c:v libx264 -pix_fmt yuv420p -crf 18 -map 0:a? -map 0:v -filter_complex "yadif,[1]scale=iw*1:-1[wm];[0:v:0][wm]overlay=main_w-overlay_w-5:5" -disposition:v:0 default output_h264.mov

  


  And what I got has three video streams. One for the logo,one for the video with logo, and one for original video.

  


  Though I put the default video stream as the one with both video and logo as you can see for -disposition:v:0 default, and it's also playing that stream. But when I tried to upload it on Vimeo or Youtube, it uses the wrong stream.

  


  ---

  


  How can I change the command line to let ffmpeg only output one stream ?
And how can I remove the extra streams for the existed outcomes ?

  


• FFMPEG - Merge multiple video in to one video, the output video has no audio

  26 octobre 2018, par Tan Pham

  My input file has 5 video and 1 picture. I want to merge all video to one video, play video at the same time.
  The layout of the output video like this :
  

  Im using ffmpeg to merge video. this is my ffmpeg command :

  ffmpeg 
  
  -i C:\VID\test1.mp4 
  
  -i C:\VID\test2.mp4 
  
  -i C:\VID\test3.mp4 
  
  -i C:\VID\test4.mp4 
  
  -i C:\VID\test5.mp4 
  
  -i C:\VID\background.jpg 
  
  -filter_complex 
  
  " nullsrc=size=1280x720 [base]; 
  
  [0] setpts=PTS-STARTPTS, scale=560x360 [video0];
  
   [1] setpts=PTS-STARTPTS, scale=280x180 [video1]; 
  
  [2] setpts=PTS-STARTPTS, scale=280x180 [video2];
  
   [3] setpts=PTS-STARTPTS, scale=280x180 [video3];
  
   [4] setpts=PTS-STARTPTS, scale=280x180 [video4]; 
  
  [5:v] scale=700x700 [image]; 
  
  [base][video0] overlay=shortest=1 [tmp1]; 
  
  [tmp1][video1] overlay=shortest=1:y=360 [tmp2];
  
   [tmp2][video2] overlay=shortest=1:x=280:y=360 [tmp3]; 
  
  [tmp3][video3] overlay=shortest=1:y=540 [tmp4]; 
  
  [tmp4][video4] overlay=shortest=1:x=280:y=540 [tmp5];
  
   [tmp5][image] overlay=570:10:enable='between(t,0,30)'"
  
   -t 30 -c:v libx264 output.mkv

  The output video layout is working fine but no audio in the output video.
  I want all audio off each video will be keep on the output video. play audio at the same time together.
