Hello, Is there a way to keep/update just the last 30 seconds from a USB webcam video stream ‘-i /dev/video0’? if I understand correctly, ffmpeg keeps the last captured stream with the use of ‘overrun_nonfatal=1&fifo_size=xxxx ‘ and overruns the old data with the new as long as it runs, are those commands only apply to UDP stream?
