Description Will Manley 2014-09-16 14:02:21 UTC
The following command fails:

    gst-launch-1.0 videotestsrc ! textoverlay ! decodebin ! video/x-raw \
                   ! fakesink

with the error:

    Setting pipeline to PAUSED ...
    Pipeline is PREROLLING ...
    ERROR: from element /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0: Internal data flow error.
    Additional debug info:
    gstbasesrc.c(2933): gst_base_src_loop (): /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0:
    streaming task paused, reason not-linked (-1)
    ERROR: pipeline doesn't want to preroll.
    Setting pipeline to NULL ...
    Freeing pipeline ...

Removing any one of "textoverlay", "decodebin" or "video/x-raw" allows the pipeline to run.  This seems to be a regression in 1.4.1 vs. 1.4.0.  I am using the GStreamer packages in debian stable version 1.4.1-1.1

I suspect this may be related to #733916 which I raised previously which relates to the `GstVideoOverlayComposition` mechanism.  I suspect this is the case as it was the same unit-test in my app that started failing. The workaround I put in my app for #733916 such that it would work with 1.4.0 no longer works with 1.4.1.  I have not yet done sufficient investigation to either narrow down the cause or work around the issue.
