ffmpeg save video in segments, time does not match
22 août 2022, par YohannI use ffmpeg to save the rtsp live stream to the local, specify the fragment size of 2 seconds and use the current time to name the video file


But the length of the returned video is not equal to 2 seconds and the interval between file names is not 2 seconds


I have tried several command line arguments


ffmpeg -i rtsp://192.168.18.119/live/test -f segment -strftime 1 -segment_time 2 -segment_atclocktime 1 -reset_timestamps 1 -an -vcodec copy ./%Y-%m-%d-%H.%M.%S.mp4

# execute result

# file names are not time aligned
