Hi All I capture video stream from webcam and show video on screen.
The same stream goes through the 'metadata' multimedia filter as shown below:
ffmpeg -y -f v4l2 -input_format mjpeg -s hd480 -r 30 -i /dev/video2 -filter_complex "[0:0]select='gte(scene,0)',metadata=print:file='movement.txt',null[X]" -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?
