    if :

    


    ffmpeg -y -loop 1 -i ./rebirth/image4.png -loop 1 -t 1.4 -i temp.png -filter_complex "[0]scale=2048:2048[video0],[video0][1]xfade=transition=fade:duration=0.8:offset=0.1" -c:v libx264 -r 30 -pix_fmt yuv444p temp.mp4

  • ffpmeg extracting frames produces too many images

    7 septembre 2019, par Abishur

    I’m using FFMpeg to extract some png files from a video using the following command :

    ffmpeg -i FILE.mp4 -vf "select=not(mod(n\,75))" -vsync vfr img_%03d.png

    the source video has a duration of 2898 seconds and a framerate of 25 FPS. This means I should be grabbing a picture every 3 seconds for 966 pictures.

    However, instead I’m getting 1158 pictures. After doing some math I’ve discovered that that is the within 2 pictures of what I would expect if I was grabbing the 75th frame from a 30 FPS video.

    I’ve tried -framerate=25 but it still produces the same amount of pictures. The video does have a variable framerate, however using ffprobe it says that the max FPS is 25.47. So even if it was at the max FPS the whole video then I’d still only expect to see 984 pictures.

    Is there anyway to tell FFMpeg that my source video is only 25 fps ? Or am I missing something obvious ?

    xcbgrab : Use the correct geometry for the region highlight

    The feature is implemented using a transparent window and drawing
    
inside it a rectangle filling the whole window to highlight it.
