  • ffmpeg encoding with VP8 producing bad looking video

    25 décembre 2017, par Radu

    I am working at a time lapse program that invokes ffmpeg via system() to encode a video from a sequence of JPGs. The user can chose a few options, including the compression codec.
    I am getting very good results when using libx264 and the mjpeg encoder. I am getting so and so results with VP9, and I am getting some horrible results with VP8.

    I am invoking ffmpeg like so : ffmpeg.exe -framerate 12 -i "./output/img_%05d.jpg" -dst_range 1 -color_range 2 -c:v libvpx -b:v 0 -threads 8 -speed 2 -crf 8 "./output/video.webm"

    I uploaded a sample to youtube : https://www.youtube.com/watch?v=eG2jxzR3Uxs (you can see the really bad frames after the 9 seconds mark.

    Any idea what I am doing wrong ?

  • ffmpeg screencasting with webcam

    6 septembre 2017, par curiouser

    I want to use the screen view of the computer in real-time for a fake webcam. I did the video action on the bottom. But the frames like the video (2.34) are forming on top of each other. How can I solve this problem.

    https://www.youtube.com/watch?v=6AZRiW3hHrw

    Load the module
    
sudo modprobe v4l2loopback exclusive_caps=1
    

    
Find the dummy device
    
v4l2-ctl --list-devices
    

    
Start the virtual-webcam (change "/dev/video1" to reflect your system)
    
ffmpeg -f x11grab -r 15 -s 1920x1080 -i :0.0+0,0 -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video1

    The server is apache with php-fpm fcgid and the cuestion is what i can runnig more process whitout problem but i don`t know becouse it limited ffmpeg to six process.

    


    I'm probe all but i think can be a limit in the ffmpeg compitated version ?

    


    When I exec the seven ffmpeg process, ffmpeg say : Conversion Falied !

    


    But I can run others process more with not be ffmpeg , is not a server limit.
