Some days ago I uploaded a video named “monitor-camera-feedback-loop-1608578433” to videos.scanlines.xyz
But when I try to watch it in Firefox, Opera or Chromium this video did not play. “The media could not be loaded, either because the server or network failed or because the format is not supported.” I am working on Debian 10.
What can i do avoid this?
How should i prepare the my videos with ffmpeg before uploading?
