  • HTML5 video player stutters even after video is loaded [migrated]

    24 octobre 2013, par Adi Ulici

    I am using jwplayer to display videos on my websites but cannot manage to make them running smoothly. They stutter, especially in full screen, although I wait for the video to fully load.

    I tried decreasing the video quality from by decreasing the bitrate from 3000k to 1800k (I use ffmpeg to convert the videos). The resolution of the videos is 1280x720 (HD).

    Any tips what should I try next ? Thanks

  • Python add video layer on a video [closed]

    8 juillet 2023, par Doğan

    I have a video in .webm format with a transparent background, and I would like to overlay this .webm video on the right down side of the main video. The main video is in .mp4 format.

    


    Is there any way to do it with python ?

    


  • Create video with size based on image and place a video somewhere with an offset

    10 mars 2024, par NoKey

    I am trying out FFMPEG and I am unsure how hard it is to do what I want. I have some device frames and I want to play a video inside the frame. For example, this is a device frame :

    


    enter image description here

    


    Now I want to play a video within the screen of the iPhone. I already got the exact X and Y offset where the video must be placed to show it correctly. I have the following challenges to make it work, and I want to make sure FFMPEG can do it before I spend to much time reinventing the wheel :

    


      


    • The output of the video must be as big as the PNG. This is already a
confusing part for me. I have the width and height already available,
but the things I saw is that FFMPEG will take over the input of the
video as final size. The final output of the video should of course
be the length of the input video.

    • The background must be transparant (so no black background, I want to
play the video on top of a website so it's nice if it's transparant and the corners are not black).

      


      • 


    • The ability to place a video somewhere with a specified X and Y
offset inside the device frame.

      


      • 


    • Not sure if it's possible in the same command, but maybe the video
needs to be resized to make it fit. I got the exact dimensions for
the video.

      


      • 


    


    The things I struggle most is point 1 where the output video must have a transparant background and where the device frame is placed in. Does anybody got tips ?
