Thanks for the tip with the framerate conversion. I tried the (amongst 
other things) the following pipeline now:

appsrc ! videorate ! ffmpegcolorspace ! avimux ! filesink
(code see [1])

but with GST_DEBUG=3 I always get these errors:
------------8<-------------
0:00:07.572208000  8929 0x85dba98 WARN             videorate 
gstvideorate.c:722:gst_video_rate_chain:<videorate_> Got buffer with 
GST_CLOCK_TIME_NONE timestamp, discarding it
0:00:07.624372000  8929 0x85dba98 WARN             videorate

gstvideorate.c:722:gst_video_rate_chain:<videorate_> Got buffer with 
GST_CLOCK_TIME_NONE timestamp, discarding it
------------8<-------------

But when I change the location of videorate it doesnt work ...

Thanks,
