To close the issue, here can be seen the changes made to segment.c
https://git.videolan.org/?p=ffmpeg.git;a=history;f=libavformat/segment.c;hb=HEAD

On 2011-12-19 was when they changed the variable names to “segment_time”, “segment_format”…

I am not using this last version because seems to work worse than 2011-10-17 version.
I has a bug (or i am using it wrong) that if i want to encode a video segmented in 10 sec chunks, the first clip is 10 seconds long, the second 20 seconds long (only last 10 sec with video data), the third is 30 secs long (only last 10 sec with video data), and so on.

I have been trying with older ffmpeg builds and i found that with this build it works:

I would like to use last build of ffmpeg if possible, but it says “Unrecognized option ‘container_format'”. Did the segmenting option names change? Is there any way to use segmenting with last build?

Thanks for your replies, i can work with it now.
