Compiling GStreamer plugin

can you please provide help how to build gstreamer / plugins-base ?

i want to try fix buffering issue Jolla-mediaplayer choppy playback while streaming by inspiration from here: [QMultimedia/GStreamer] Set the buffer size higher to avoid stuttering - together.jolla.com
but first i want to be sure that i will be able to compile it before do any changes…

tried method described here Building packages - advanced techniques | Sailfish OS Documentation

cloned GitHub - sailfishos/gstreamer
but failing to build:

FAILED: libs/gst/helpers/ptp/libgst_ptp_helper_conf.rlib

error: failed to create encoded metadata from file: No such device (os error 19)
