I am using gstreamer 1.8.3. If I remember correct, previously, I can set
caps-change-mode to 1 (delay) for capsfilter.

However, now it shows:  'GstCapsFilter' has no property named
And when I check by gst-inspect-1.0 capsfilter:

                        flags: readable, writable

There is no caps-change-mode.

I also try to reinstall gstreamer-1.8.3 core plugins, but still cannot find

Thanks in advance!
