Hello FFmpeg Team,
Good evening.
I do understand that we can synchronize audio/video stream using the
"*itsoffset*" option as
documented in this website:

=========================================================================================================================
In fact, I have tested it and it is indeed working. The following line
delays the audio stream by 1 second to synchronize it with
=========================================================================================================================
ffmpeg -y -i http://192.168.0.11:8090/VIDEO_CAM1.mpg -itsoffset 1.0 -i
http://192.168.0.11:8090/AUDIO.mp2 -map 0:0 -map 1:0 test.mp4
=========================================================================================================================
I use ffserver as input source by the way, feeding it with streams from
an IP camera (video) and ALSA (audio).
However, I would like to make the synchronization automatic. Say,
compare the timestamps from each stream and find their difference,
then use the difference as parameter to the "*itsoffset*" option?
Hoping to receive an enlightening response. Thank you very much for your
good product!
Regards,
Guillermo
