            Bug ID: 776166
           Summary: Using set_window_handle on raspberry pi, need to set
                    pipeline to NULL to change file.
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: don't know

     GNOME version: ---

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:

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/*
