• FFmpeg overlay PNG after scaling has not necessary black borders

  24 mars 2021, par Mikołaj Henklewski

  I have two PNG files that I want to add to the video :

  


  

  • Two lines text

  


  • Circle

  


  


  but on the final video, they have black borders (they do not have it originally !) Actual Result.. The question is why FFmpeg is adding it on scale effect, and how to avoid adding it ? Command is :

  


  ffmpeg -i 3d9678e2e58c4d08a24363468d0cfd3e.mp4 -i caption-1616544596077-d.png -i caption-1616544596080-d.png -filter_complex

• Streaming an IP camera through node.js

  18 juillet 2021, par Jacob

  I am trying to get an IP camera stream to run in the browser, and eventually phones. However, I am running into a problem accessing the RTSP stream through ffmpeg.
I am running the command below, substituting the correct info. I changed the camera to a static IP address and copied the IP address to STATIC_IP.

  


  /opt/homebrew/bin/ffmpeg -i rtsp://USER:PASS@STATIC_IP:554/stream1 -fflags flush_packets -max_delay 5 -flags -global_header -hls_time 5 -hls_list_size 3 -vcodec copy -y .\videos\ipcam\index.m3u8
