autovideosink with GstVideoOverlay -> handle gets destroyed by OS on minimize

Tue Dec 16 04:20:27 PST 2014

To reproduce my problem without code:

(1. Step)
gst-launch-1.0.exe -v --gst-debug=GST_ELEMENT_D3D*:6 filesrc 
location=d:\t.avi  !
decodebin name="dec" ! d3dvideosink  dec. ! audioconvert ! autoaudiosink

(2. Step)
Minimize appearing Video Window
Result: ERROR: from element 
/GstPipeline:pipeline0/GstDecodeBin:dec/GstAviDemux:avidemux0: Internal 
data stream error.

Can't see any matching Bug Report. Should I create ?

[tested win8.1 64Bit]
