[gst-devel] how to let the flag "resend-latest" work in output-selector ?

[chen r. <rui...@ti...>]

Hi all,

I modify the example in 
gst-plugins-bad/tests/icles/output-selector-test.c and create new 
pieline like this:
                                                    filesink
                                                 /
  videotestsrc -- output-selector
                                                 \
                                                    autovideosink

I think if i set "resend-latest" flag to TRUE, when i play my file, it 
will fluency. But it does not, the same as resend-latest = FALSE. So how 
to use let the flag work?


here is my test base on output-selector-test.c
