I'm new one gstreamer and i have a problem to extract the images from  
files created with ffmpeg. Launching the
gstreamer on my Win10 PC in with

gst-launch-1.0.exe filesrc location=F11.mov ! decodebin ! videoconvert  
! video/x-raw,format=GRAY8 ! multifilesink location=u%d.bmp

I get following messages:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Missing element: H.265 decoder
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0:
