I capture video stream from webcam and show video on screen.
The same stream goes through the 'metadata' multimedia filter as shown
ffmpeg -y -f v4l2 -input_format mjpeg -s hd480 -r 30 -i /dev/video2
-map '[X]' -pix_fmt yuv420p -f xv Title
The text file 'movement.txt' gets information about each frame. BUT data
is written to text file 'movement.txt' buffered. Is there any way to
write data to text file 'movement.txt' as each frame is processed?
