I am cross compiling gst-libav-1.8.0 and having some problem blocking me for several days. Would you please help?

First, 1.8.0 is already two years old, we recommend using the newest
stable version (which is 1.14.1 right now).

This is on purpose, for many containers, GStreamer has it's own
demuxers that are better integrated in our pipeline model.
