No it isn't.  Google is wonderful, please make use of planetary search
facilities.

There's a good reason why I dumped a full debug log using GST_DEBUG=*:9,
analysed it for the cause of the failure, and tried several different
pipelines, including the standard bayer2rgb plugin.

Please don't blame this on random stuff after analysis of the logs _and_
reading the appropriate plugin code has shown where the problem is.  I
know gstreamer can be very complex, but it's very possible to analyse
the cause of problems and pin them down with detailed logs in conjunction
with the source code.
