This patch has a strange side effect. With it gst-libav1.0 (version 
1.3.2) gets compiled incorrectly so that when the plugin is loaded by 
gstreamer it segfaults:
ERROR: Caught a segmentation fault while loading plugin file:
debian/gstreamer1.0-libav/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstlibav.so

Removing these demuxers from the 2.3 release makes gst-libav1.0 work again.

Any idea what the underlying problem could be?

Best regards,
Andreas
