16. Joining multiple video parts into one

FFmpeg will also join the multiple video parts and create a single video file.

Create join.txt file that contains the exact paths of the files that you want to join. All files should be same format (same codec). The path name of all files should be mentioned one by one like below.

/home/sk/myvideos/part1.mp4

/home/sk/myvideos/part2.mp4

/home/sk/myvideos/part3.mp4

/home/sk/myvideos/part4.mp4

Now, join all files using command:

$ ffmpeg -f concat -i join.txt -c copy output.mp4

        listen       81 default_server;

        listen       [::]:81 default_server;

        server_name  _;

        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.

        include /etc/nginx/default.d/*.conf;

        location / {

        }

        error_page 404 /404.html;

            location = /40x.html {

        }

        error_page 500 502 503 504 /50x.html;

            location = /50x.html {

        }

        location /test1/ {

                proxy_set_header X-Real-IP $remote_addr;

                proxy_set_header Host $host;

                proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;

                proxy_pass http://localhost:3001/;

        }

        location /test2/ {

                proxy_set_header X-Real-IP $remote_addr;

                proxy_set_header Host $host;

                proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;

                Host proxy_set_header $ HTTP_HOST;

                proxy_pass http://localhost:3002/;

        }

    }
