Compositor question

[William Salibrici]

Sean,
Thank you for your reply.
My third video input is already from a videotestsrc but is-live was false.
So – I set is-live to true which did not correct the problem.
Regards,

Bill

I had this issue as well, try connecting a videotestsrc with is-live=TRUE

And then compare with is-live=FALSE

I have a pipeline [not shown here] that uses a compositor element to combine video from three different inputs, video A, B, and C.
The pipeline runs just fine when all three video inputs have data. However, if video C input stops flowing, that also stops video B [which still has data] from appearing in the composite output. In other words, if video C input goes away, the composite output contains only video A data. I tried changing the order of the inputs but the compositor behavior remains basically the same. If only one of the compositor video inputs goes away, I would expect the composite output to contain the other two inputs which are still flowing regardless of the order in which they arrive at the compositor inputs. But that does not appear to be the case.
My development machine is windows 7 and I’m using GStreamer 1.10.4 with your windows pre-built binaries.
Any ideas on what could be done to correct this compositor behavior?
Thanks so much for your help,
Bill
