filesink with 60 fps

[Ilya Aleshkov]

Oh, yes. Thank you! Sorry for such a dumb question )

I've checked everything. Now timeline works pretty good in built-in Windows
media players but not in VLC. VLC's timiline stops and jumps sometimes.
It seems x264 still produces more accurate files. It's not my goal, but it
would be great to generate files in most proper way. I just would like to
be sure that I can read these files (again by GStreamer) without any issues.
Now I'm able to go forward.

Thanks again! I know why GStreamer is so powerful - just because of
community!
