Cutting a h.264 video stream into smaller files

[ragavas]

Hi
I am streaming a h.264 video from a surveillance camera through vlc in C program in linux and write it to a fifo pipe. Then i read from this fifo pipe and write to a file for 10sec. after completing writing for 10sec i move on to write to another file. However, there are some frames lost when i play back the split files i.e some frames are lost when one video ends and the next video starts, why does this happen? am i missing something technically? I even tried writing to files which were already created and opened (so that i wanted to eliminate the time taken to open and close a file which is negligible though (or isn't it?)) why some frames are lost towards the end and start of next video?! there is no other process reading from the fifo. i know i can use some cutters available but i have to do it through a C program only! Plz help...

Why so such short cuts?

Maybe try ask in the official VLC forum, http://forum.videolan.org/viewforum.php?f=32

why does this happen?

probably because you are not cutting on key-frames or you are missing frames since you are not buffering the frames before writing them.

Thanks for replying. Yeah have posted in vlc forum as well.
@Selur
Buffering is not required since im writing to a pipe/fifo and hence there are no chances of frames getting lost. and im running the writing to the pipe and reading from the pipe in different threads.
