  • Record region of screen using FFMPEG ? [closed]

    13 février 2024, par pookie

    I am looking to record a defined area of the screen at as high FPS as possible. I then need to extract the milliseconds for each frame.

    



    I was looking at FFMPEG and found that it has (or had...) an option called x11grab, so I tried the following to record a region of the screen :

    



    ffmpeg -f x11grab -s 1678x1050 -i :0.0+7,53 -r 25


    



    It doesn't work : I get an error Unknown input format: 'x11grab'

    



    I tried with xcbgrab too, but I get the same error of Unknown input format...

    



    I have seen this SO post, but I am using Windows 10, and it did not help me.

    



    Google tells me that this argument is now deprecated. I cannot find an examples of how to record just a part of the screen.

    



    I want to take a partial screenshot because I need as high a FPS as possible and my assumption is that taking a partial capture will be faster than taking a full screen capture. Is that correct ? If not, of course I could take a full screen capture and the crop out region of interest... and if that is the case, does anyone know how to do that ?

    


  • vf_scale_vaapi : Crop input surface to active region

    vf_scale_vaapi : Crop input surface to active region

    If the input has been decoded from a stream which uses edge cropping
    
then the whole surface need not be valid.  This defines an input
    
region for the scaler so we only use the active area of the frame.

    lavfi/overlay_vaapi : set input region for overlay video to NULL

    Otherwise main and overlay videos share the same input region. Note NULL
    
pointer imples the whole overlay video will be processed.
