DRM decryption (from LG)¶

Enable DRM decryption for live streams using PIM library from Zenyth company. (as LG monitors can do with LG headends)

1. to build the new libgstmpegtsdemux.so for gstreamer

   copy mpegtsdemux folder to /data/Yocto/poky/build-rockchip/tmp/work/armv8a-poky-linux/gstreamer1.0-plugins-bad/1.20.7-r0/gst-plugins-bad-1.20.7/gst/mpegtsdemux
   new files are: meson.build files, tsdemux.c, mpegtspacketizer.c

2. force build gst-plugins-bad-1.20.7 from yocto

source oe-init-build-env build-rockchip/
bitbake gstreamer1.0-plugins-bad -c compile -f

3. for succefull build (gst-plugins-bad) copy library and include files to gstreamer1.0-plygins-bad/1.20-7/recipe-sysroot

4. to the device
   copy include files to /usr/include
   copy librkcrypto.so to /usr/lib
   extract lib_aarch64.zip and copy to /usr/lib
   copy provided libgstmpegtsdemux.so to /usr/lib/gstreamer

   init_system script can do the above operations (library files must be in /firmware/htdocs/python folder)

5. pim_v4_14.tar contains the SDK, you can build test software for linux PC or aarch64 devices
   documentation for PIM library included
