python doesn't matter here.

The .pc files aren't needed here.

The script looks mostly fine.  I have the CFLAGS for gst-plugins-bad as
CPPFLAGS here.

What we need now is ensure that the pipeline is using the correct memory type.

Could you past the output of:

$ gst-inspect-1.0 omxh264dec
$ gst-launch-1.0 -v playbin uri=file:///path/to/file.h264
