fakesink not working as a videosink with playbin2 ?

Hey,

basically, I create a playbin2, i pause the pipeline, i create a fakesink,
and set it as the video-sink for playbin2.

When I play the file, the handoff callback of the fakesink is not called.
Instead, a new window is created, where the stream is rendered. It seems
that settin the video sink as the fakesink is not working (that is, i'm
doing something wrong). The code is below.

Does someone see where the problem is ?

thank you

Vincent Torri

Maybe you set it too late. Imho you should just be able to set "video-sink" to
your fakesink instance right after playbin2 creation.

You're right. Setting it before pausing works. I tried to set the sink to
NULL before pausing and setting the sink after, but it does not work too.
