  • Extract final frame from a video using ffmpeg

    14 mai 2020, par Saavestro

    I know how to extract the first frame by using

    



    ffmpeg -ss 00:00:00 -i input.mp4 -vframes 1 -q:v 31 output.png

    



    Here, the option -ss requires to know the exact time of the frame to extract.

    



    I would like to have the final frame of any .mp4 without knowing the exact final time of the video.

    



    Is there a way to achieve this ?

    


  • x11grab : Check the XQueryPointer return value

    x11grab : Check the XQueryPointer return value

    The paint_mouse_pointer() code uses XFixes to retrieve the cursor
    
coordinates, but XFixes gives no information about which screen the
    
pointer is on ; this results in always drawing the cursor on the
    
captured screen even if the mouse pointer was on another screen.
    

    For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
    
the cursor was being drawn in the captured image even when the mouse
    
pointer was actually on screen 0, which is wrong and visually confusing.

  • ffmpeg fails exporting in batch file, but works on terminal [closed]

    16 mai 2021, par davidlao

    I'm trying to make it so when my program finishes making JPGs, it converts to MP4. A screen recorder, basically.

    &#xA;

    Before you ask me, yes, my JPGs are named 1, 2, 3... and so on for each frame.

    &#xA;

    Everything is fine, except for one thing. Whenever I run ffmpeg to export through the terminal, it works like a charm, but whenever i run ffmpeg through a batch file, it throws this error which i do not understand at all :

    &#xA;

    v: No such file or directory&#xA;

    &#xA;

    In case anyone needs my batch code, here it is :

    &#xA;

    @echo off&#xA;color 1e&#xA;title Exporting...&#xA;echo Exporting FFMPEG video, please wait&#xA;cd /D %~dp0&#xA;ffmpeg.exe -nostdin -i %d.jpg -c:v libx264 -vf "fps=10,format=yuv420p" out.mp4&#xA;echo Done.&#xA;pause&#xA;exit&#xA;

    &#xA;

    By the way, yes, "ffmpeg.exe" exists and runs, but only exports without errors when ran via terminal.

    &#xA;
