hi
yes ,that is right !
but the option "segment_time" seems not have any function.
when I set -segment_time 3, ffmpeg does not split multiple files by each 3
seconds.
the log :

ffmpeg -sn -f video4linux2 -r 30 -s 1280x720 -input_format h264 -i
/dev/video1
 -vcodec copy http://localhost:8090/feed2.ffm -vcodec copy -map 0 -f
segment -s
egment_time 3 -segment_format mpegts /var/stream%05d.ts
