If the TV news show 14:00:00 or with DVB Snoop I check the time at 14:00:00, my recording starts at 14:00:03 or 14:00:04. I'm doing this test: ffmpeg -y -i udp://@239.255.7.3:1234 -r 25 -vcodec libx264 -acodec libfdk_aac -ab 48000 -ar 22050 -ac 1 -s 352x288 -f segment -strftime 1 -segment_time 300 -segment_format mp4 /var/tmp/test-Tvnews-%Y%m%d_%H%M%S.mp4 Anyone can help? Thanks! :-)
