GNOME Bugzilla – Bug 643480
Internal data flow problem for previews.
Last modified: 2013-11-12 16:53:34 UTC
When clicking on the "Effects" button, the previews are showing very badly or even not showing and the following message is prompted 9 times: ** (cheese:31581): WARNING **: Internal data flow problem. I guess this happens 9 times, because there are 9 effect's previews. This is happening in master and in the gtk+-3 branch: https://github.com/Patriciasc/Cheese-GTK-3
do you have any idea why this happens?
It is something that was happening in master before, so it might have been around for a long time now. It could be GStreamer, Clutter?
It's GStreamer. The message is posted on the bus, and Cheese prints it. I had never noticed that Cheese doesn't say it is a GStreamer warning when that happens. This is the aditional information from the warning message: gstbasesink.c(3620): gst_base_sink_chain_unlocked (): /GstCameraBin:camerabin/GstBin:video_filter_bin/ClutterGstVideoSink:cluttergstvideosink1: Received buffer without a new-segment. Assuming timestamps start from 0. I think this happens because of the way we connect effects while playing.
I'm changing the importance of this bug to normal since it just displays warnings but nothing else apparently happens.
I can reproduce on Mageia Cauldron: cheese-3.3.90-3.mga2 $ cheese --gst-debug-level=3 [...] 0:00:05.675553106 22498 0x4d84450 WARN basesink gstbasesink.c:3626:gst_base_sink_chain_unlocked:<cluttergstvideosink1> warning: Received buffer without a new-segment.

No other button works.
Still available in cheese-3.3.92
Still available in cheese-3.5.2
This should not be a problem any longer, as any missing plugins are now ignored (see bug 702995). Please reopen if the bug still exists in Cheese 3.10.2 or greater.
