[gst-devel] Internal data flow error / streaming task paused, reason not-linked

[Stefan Kost]

hi,

with the attached examples I get these warnings since a while.
Unfortunately ignoring them isn't good enough. What I do in my app (and
also in the attached examples) is to unlink elements while the pipeline
plays. I block the src-pad before unlinking. I believe it was working
some weeks ago. Right now I get this warning and after a while I hear
random bleeps or nothing at all.

WARN  (0x80d6848 - 0:00:04.250236000)              basesrc(24108)
gstbasesrc.c(1318):gst_base_src_loop:<src2> error: Internal data flow error.
WARN  (0x80d6848 - 0:00:04.250284000)              basesrc(24108)
gstbasesrc.c(1318):gst_base_src_loop:<src2> error: streaming task
paused, reason not-linked

To me this sounds like the peer element of the sources that just have
been disconnected, still pulls data.

I'd like to turn this into a test-case. Not sure how to determine
failure (its not crashing). Maybe intercepting the log or cheking the
bus for GST_MESSAGE_WARNING|GST_MESSAGE_ERROR.

Any idea where the culprit is?

Stefan
