    This is in preparation for sharing even more stuff
    
common to the fixed and floating-point encoders.

  • record Linux Wayland/DRM screen using ffmpeg's kmsgrab device with superimposed webcam

    7 février 2020, par nrdxp

    Setup is Linux, ffmpeg using kabylake iGPU.

    I am capturing a running sway instance using the kmsgrab device, which requires the use of a hardware backend to coherently process the image on my hardware. Only VA API fits this bill. I want to overlay the webcam in the bottom right corner during encoding. However, attempts at manipulating the filter graph to accomplish this have been unsuccessful. This is ultimately for Twitch/Tube stream.

    Right now, I am actually capturing the webcam to an sdl window, and simply recording the screen using separate instances of ffmpeg. This doesn’t actually solve my problem since the window is easily disguised by workspace switching or other windows.

    This is the workaround :

    #!/usr/bin/env zsh
    

    
# record webcam and open it in sdl window
    
ffmpeg -v quiet -hide_banner \
    
  -re -video_size 640X480 -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i /dev/video0 \
    
  -vf 'format=nv12,hwupload' -c:v hevc_vaapi -f hevc - \
    
  | ffmpeg -v quiet -i - -f sdl2 - &amp;
    

    
# wait for webcam window to open
    
until swaymsg -t get_tree | grep 'pipe:' &amp;>/dev/null; do
    
  sleep 0.5
    
done
    

    
# position webcam in the bottom right corner of screen using sway
    
swaymsg floating enable
    
swaymsg resize set width 320 height 240
    
swaymsg move position 1580 795
    
swaymsg focus tiling
    

    
#screencast
    
ffmpeg -format bgra -framerate 60 -f kmsgrab -thread_queue_size 1024 -i - \
    
  -f alsa -ac 2 -thread_queue_size 1024 -i hw:0 \
    
  -vf 'hwmap=derive_device=vaapi,scale_vaapi=w=1920:h=1080:format=nv12' \
    
  -c:v h264_vaapi -g 120 -b:v 3M -maxrate 3M -pix_fmt vaapi_vld -c:a aac -ab 96k -threads $(nproc) \
