• FFserver : cannot connect via rtsp

  27 avril 2016, par newfoundstory

  so im currrently trying to stream my windows desktop using ffmpeg into a raspberry pi running ffserver.
  The client software im using needs to use RTSP, however i cannot connect to the stream no matter what i try.
  I even used VLC in the messages it just says it cannot connect to the stream.
  Any help would be greatly appreciated !
  Im attempting to access the stream with rtsp :// 169.254.70.227 :8544/test.flv, as soon as i do it stops the ffmpeg feed

• Upload to S3 bucket from FFMpegCore

  18 avril 2022, par user1765862

  I'm using FFMpegCore to create image from the video on 5th second.

  


  var inputFile = "images/preview_video.mp4";
var processedFile = "path-to-s3-bucket";
await FFMpeg.SnapshotAsync(inputFile, processedFile, new Size(800, 600), TimeSpan.FromMilliseconds(5000));


  


  How can upload this processed file (image) to my s3 bucket using FFMPegCore Snapshot ?
