Description Stuart Axon 2016-12-16 13:15:08 UTC 
On raspbian, if I use set_window_handle and want to change the file on a filesrc, setting the pipeline state to READY doesn't work.

The only way to make this work is to set the pipeline to NULL, which results in a black screen.


There is a program to demonstrate this and other bugs here:

https://github.com/stuaxo/gstreamer-dispmanx-demo


Run 

python-multi.py --enable-bcm rgba_pngs/*

To see the black screen.



To try running it with the pipeline state set to NULL instead, run:

python-multi.py --enable-bcm --null-state rgba_pngs/*

I realised this is a duplicate of this bug -
https://bugzilla.gnome.org/show_bug.cgi?id=776091


Without the patch there, then using set_window_handle and trying to advance to the next file results in a black screen, whether you use NULL or READY.

With the patch it works, but only setting to NULL
