Test program

Hi,

I have the following pipeline (I really have a more complicated pipeline but I
have reduced the complexity trying to understand the problem):

videotestsrc!videorate!videoconvert!capsfilter!videorate!videoconvert!capsfilter!autovideosink

I have detected that if I change dynamically the framerate in the second
capsfilter I get a non negotiated error in the videoconvert. I have the
following trace:

0:00:07.816591895 32762      0x1a0c940 WARN           basetransform
gstbasetransform.c:1414:gst_base_transform_setcaps:<videoconvert1> transform
could not transform video/x-raw, width=(int)320, height=(int)240,
framerate=(fraction)16/1, pixel-aspect-ratio=(fraction)1/1,
interlace-mode=(string)progressive, format=(string)YUY2 in anything we support

This problem breaks the pipeline if you use another source like the
uridecodebin.

I have attached a test program to reproduce the error. That program creates the
shown pipeline and it changes the caps of the second capsfilter each second. If
you execute the program with GST_DEBUG=2 you could see the error traces.

Have you seen this error before? Am I doing something wrong?

Thanks for your time.
Regards.
