playbin3/decodebin3 fails to play video/x-divx,divxversion=3 files if gstreamer-vaapi is installed
Submitted by Michael Olbrich
With gstreamer-vaapi installed, playbin3 fails to play some old divx files (e.g. ).
From what I can tell, vaapidecodebin is selected based on the static caps. Caps negotiation then fails at a later step and decodebin3 tries again. However,
vaapidecodebin is not blacklisted so it's selected again in an endless loop.
The old playbin still works: when vaapidecodebin fails it tries the next decoder and succeeds to play the file.
