• Does FFmpeg download the video on server to generate screen shot from S3 video url ?

  13 décembre 2019, par Tashi

  I am running the following command to generate screenshot from an S3 video url in my server. I want to know if FFmpeg downloads the video to server disk or memory before generating the screenshot. Let me know if anyone knows about this, thanks.

  ffmpeg -i "http://bucket.s3.amazonaws.com/video.mp4" -ss 00:00:10 -vframes 1 -f image2 "screeenshot.jpg"

• How can I change the fps of video without restarting the video stream, which is being played by ffmpeg command ?

  7 juin 2018, par Mehta Naisargi Rajeshbhai

  I am playing the video (.mp4) in VLC by this below command in terminal :

  ffmpeg -i input_file.mp4 -crf 18 -c:a copy -r 60 http://localhost:1234/feed1.ffm

  Currently it is 60 fps.

  Now I want to change the fps during the playback of video file, so is it possible to change the fps during runtime without restarting/breaking the video using FFmpeg ? And if it is possible then please guide me.
