But the "segment" seems does not meet my requirement.
I would like to save multiple files that each file hase fixed size.
for example:
ffmpeg -sn -f video4linux2 -r 30 -s 1280x720 -input_format h264 -i
/dev/video1 -vcodec copy http://localhost:8090/feed2.ffm -vcodec copy
/var/tmp/usb/sda1/test1.ts
the command can capture live video data from /dev/video1 and send to
feed2.ffm for ffserver , then ffserver can output to remote side for
preview,
and can write video data to test1.ts, continuely.
the command can not set the file size while the file "test1.ts" is get
bigger.
I would like to :let ffserver output the live stream to remote side for
preview and save the live video stream to local SD card (multiple files)by
fixed size.

if the segment you mentioned can get the purpose that I want,
Could you kindly help to modify the command I write above for show me the
example?

every input is very appreciated!!!!
thanks a lot!
