  • C run linux shell command(fmpeg) 10x slower than typing directly in terminal

    14 novembre 2014, par dadylonglegs

    CLOSED

    I’m writing an application that execute a linux shell command (ffmpeg) from my C code. Such as :

    char command[2000];
    
sprintf(command, "ffmpeg -i %s/%s -r 1 -vf scale=-1:120 -vframes 1 -ss  00:00:00 %s.gif", publicFolder, mediaFile, mediaFile);
    
system(command);

    To extract video thumbnail from a specific video. But the strange that it is too much slower when executing shell command form C compare to typing directly to the terminal. I have no idea about this.
    Can anybody help me pls ?. Thanks in advance.
