  • FFMpeg : Remove duplicate frames AND maintain interlaced field order

    9 novembre 2017, par Meiereika

    I have a video file that contains duplicate frames every 2-3 seconds.

    I was able to remove those redundant frames with the following command line :

    ffmpeg -i input.mp4 -vf mpdecimate,setpts=N/FRAME_RATE/TB out.mp4

    However, at the same time the video was also transcoded into a progressive clip rather interlaced (just like the original file).
    How can I force FFmpeg to maintain the interlaced structure, while at the same time removing the duplicate frames ?

    I’m totally new to FFMpeg and have no clue about command lines and all that stuff.
    Maybe you could just help me out with the right code ?

    Thanks,
    Daniel

  • How to show the camera preview always in the Spydroid-ffmpeg project

    11 avril 2013, par user2182013

    I'm tring to readapt the https://github.com/vanevery/spyd-ffmpeg project to my own. This project streams the video and/or audio captured by the phone camera via rtsp and it can be received in a computer or so running vlc or similar. My problem is that the app just shows the preview of the camera when receives a connection, but I'd like to show it always. I've tried hundred of things but it always crashes. I cannot find any startPreview() or similar method and I don't know where exactly in the code it is started in order to modify it. Any clue ?

    Thanks.

  • FFmpeg extract every frame with timestamp

    7 mars, par Ruan Matt

    How can I extract every frame of an video with the respective timestamp ?

    


    ffmpeg -r 1 -i in.mp4 images/frame-%d.jpg


    


    This code extracts all frames, but without timestamp. Since Windows do not allow " :" in filenames, I'll replace it for ".". I would like something like this :

    


    frame-h.m.s.ms.random_value.jpg
frame-00.10.15.17.1.jpg
frame-00.11.16.04.2.jpg
frame-00.11.17.11.3.jpg
frame-00.11.17.22.4.jpg
frame-00.12.04.01.5.jpg
...


    


    The reason of "random id" is to allow repeated frames without replacing them.

    


    I have tried :

    


    ffmpeg -r 1 -i rabbit.mp4 images/frame-%{pts\:hms}.jpg


    


    But this doesn't work ! => Could not open file : images/

    


    I have no clue how can I do that ! Can you help me ? Thank you.
