running pipeline without sinkelement?

Kocsis Tibor
Hi,

I have a pipeline in PLAYING state. Is there any way to hold in the
pipeline a source element in PLAYING (e.g. v4l2src) without a
sinkelement, or I always have to use a sinkelement on the end of the
pipeline (e.g. a fakesink)?

Regards
Tibor

You can't run a pipleine with loose ends. As soon as a pad_push/pull
happens on an unlinked pad you will get a dataflow error that is
critical and stops the pipeline. Just add a fakesink or block the pad.
