gcc -o demuxdecode demuxdecode.c -L/usr/local/lib -Wl,--start-group
-lavformat -lavcodec -lavdevice -lavfilter -lavutil -lswscale -lswresample
-Wl,--end-group -ldl -lm -lz -lpthread -lrt -mfpu=neon

I tried skipping frames, but then it had too many errors - I need to find
which P frames are reference frames and not skip those.
