  • Chromakey filter to display transparent keyboard while recording game screen using ffmpeg

    31 janvier 2020, par captain_majid

    I’m trying to display a transparent keyboard like this one (he is using OBS studio) :
    https://www.youtube.com/watch?v=6RCXyh2aICY

    So I’m setting all "NohBoard v1.2.2" colors to green (0x00FF00), except the letters, then :

    ffmpeg -y -f gdigrab -framerate 30 -draw_mouse 0 -i title="NohBoard v1.2.2" keyboard.mp4
    
ffmpeg -y -i keyboard.mp4 -c: png -vf "chromakey=0x00FF00:similarity=.200" keyboard1.mp4
    
ffmpeg -y -i gameplay.avi -i keyboard1.mp4 -filter_complex "[1:v] scale=560x180 [kb]; [0:v][kb] overlay=x=W-w-520:y=H-h-0 [done]" -shortest -map [done] test.mkv

    Everything works great so far, but can I use 1 command for this ?

  • Inconsistent behavior when using ffmpeg.exe to take a screen shot of a streaming video every 100 milliseconds ?

    29 janvier 2020, par AlvinfromDiaspar

    I am using ffmpeg.exe to produce a screen shot of a streaming video (H.264 encoded video on a UDP connection).

    I am wondering if calling this every 50-100 milliseconds is too much load. The screenshots being produced is sporadic and not nearly enough (im taking a screenshot every 50-100 ms). Note that after i run the command i attempt to do a taskkill (to make sure the process isn’t hanging around).

    How can i ensure that the ffmpeg.exe process completes its execution before i taskkill it?

    The command argument im using for ffmpeg is the following :

    -y -i udp ://0.0.0.0:11111 -ss 00:00:01 -vframes 1 -q:v 1 ScreenShot.jpg

  • Screen reocrd with avformat_open_input x11grab return -5

    16 janvier 2020, par Truong Hoang

    I am working with libavformat and use x11grab to record screen on Ubuntu and also windown.

    I stuck with method of libavformat is avformat_open_input always return -5 although pFormatCtx and iformat not null

    This is may code

    //Show Dshow Device
    
void ScreenRecorder::Show_dshow_device() {
    
    av_register_all();
    
    avformat_network_init();
    
    avdevice_register_all();
    
    AVFormatContext *pFormatCtx = avformat_alloc_context();
    
    AVDictionary *options = NULL;
    
    AVInputFormat *iformat = av_find_input_format("x11grab");
    

    
    printf("========Device Info=============\n");
    
    int temp = avformat_open_input(&pFormatCtx, ":0.0+10,20", iformat, &options);
    
    cout << temp << endl;
    
    printf("================================\n");
    
}

    My Code
