When splitting video, it's not starting from the 0th second. I followed the syntax I read in many posts, e.g.:

ffmpeg -ss 00:00:00 -t 00:00:15 -i 'Wildlife.wmv' '1.wmv'
ffmpeg -i 'Wildlife.wmv' -ss 00:00:00 -t 00:00:15 '1.wmv'
ffmpeg -ss 00:00:00 -i 'Wildlife.wmv'  -t 00:00:15 '1.wmv'

With none of the above commands I'm able to split a video from the beginning to 15 seconds.

ffmpeg-php version string: 0.6.0-svn

libavcodec build number: 3426306

@mark4o please see below output of console

Please include the complete ffmpeg console output. (Use the {} preformatted text button for commands and output.) –  mark4o Mar 9 '13 at 17:12
    
It's not clear what the actual problem is. What happens instead? Does the video start from another timestamp? Does it convert at all? Do you get any errors? (If you're really using version 0.6.0, then I suggest you update to a more recent one though, just in case. 0.6.0 was released in June 2010.) –  slhck Mar 9 '13 at 21:36
    
@slhck above syntax give me full video instead of 15 sec video from beginning. –  Smit Shah Mar 11 '13 at 5:05
    
From your output it looks like it actually only encoded 15.10 seconds. Please try with a more recent version of FFmpeg. There's no point in trying to troubleshoot software that has had thousands of bugs fixed since then. –  slhck Mar 11 '13 at 7:06
