            }

    application push {
    live on;
    push rtmp://a.rtmp.youtube.com/live2/djfghjkdfhgkjsdfglsjdfhj;
            }

            application pushh {
            live on;
            push rtmp://127.0.0.1:19350/rtmp/453uy4uty8ryt85ty85yt8;
            }
   }
}


  


  Now for the life of me i just cannot get my brain to work.
i am very new to rtmp and have tried a dozen other ways before coming here for help.

  


  i know this is going to be something i where i am making such a simple mistake

  


  but on the other hand paying over $49 for restream.io for a shoddy service i just have to learn this for my own servers

• Adding a text overlay with constant size to a video with varying resolutions using ffmpeg

  22 décembre 2020, par BetaLixT

  I have a video with different resolutions at different points of the video and need to add a text overlay to it. I'm new with ffmpeg, the following is one of the commands I've tried

  


  ffmpeg -i input.mp4 -vf "drawtext=text='Hello World'" -c:a copy output.mp4


  


  But the output has blurry text with it resizing every few seconds (I'm guessing because of the various resolutions in the video) and some parts of the video have their aspect ratios altered.

  


  Information on input file

  


  The input.mp4 video is generated from some .h264 raw data converted to mp4 and some blank mp4 generated that are all concatenated together, following are the commands

  


  h264 to mp4 :

  


  ffmpeg a.h264 -c copy a.mp4


  


  blank mp4

  


  ffmpeg -t 5 -f lavfi -i color=c=black:s=200x200 -c:v libx264 -tune stillimage -pix_fmt yuv420p -video_track_timescale 1200000 b.mp4


  


  Concat :

  


  ffmpeg -safe 0 -f concat -i list.txt -s 720x960 -c copy input.mp4


  


  I'd be thankful for any advice on how I could achieve this
