Thanks a lot, this was a big help. There’s also a format converter available that will transcode to more usefull formats.

I had the additional problem that my source file(s) were > 4GB – neither the converter nor the filters will touch those files.

Found a way to split them though, I used a linux system for manipulation the files, should be possiblein windows with the right tools as well.

The files have a fixed header of 40 bytes followed by the av stream.
1) truncate a copy (part1.mp4) of the original file to just under 4GB (perl -e “truncate ‘part1.mp4′, 2**32-1″).
2) use the “cut file” feature of the format converter to cut out ~10 seconds near the end of the file from 1)
3) get the first ~32 bytes of the AV stream from this cut sample (dd if=sample.mp4 bs=1 count=32 skip=40 of=pattern.dat)
4) find this pattern in the original file (binfind -f pattern.dat orig.mp4)
5) truncate your copy to the offset found at step 4 (perl -e “truncate ‘part1.mp4′, 4286789252″)
6) build a new file with the rest of your original (dd if=orig.mp4 bs=1 count=40 of=part2.mp4; dd if=orig.mp4 bs=1 skip=4286789252 >> part2.mp4)

if your part2.mp4 is still > 4GB, repeat until you’re left with parts < 4GB that can be handled using the tools from hikvision.com.

 Спасибо, реально заработало видео. Весь интернет облазил и вот только у здесь нашел.
