Apparently, he only uses Kodi in PVR, so he makes the Stream in Audio/Video.
He did a VDR, but only for Raspberry Pi with I imagine the VDR Raspberry Pi HD Device plugin.
I allowed myself to open a topic on the forum of VDR, I explain here the possibility of integrating the OSD of VDR on Kodi ! : Skin in FrameBuffer - Without X11 ? - VDR-Skins - VDR Portal
But I block from the start on this skin story, it's very frustrating.
Despite my weeks of work, I abandon the one on OpenATV, because GSTreamer works only in the opening of file, which is not the case of Enigma2 in DVB. I gave up even more, when I saw that some definitions were added for Amlogic, it would take me too long to make a PC version, Amlogic, Raspberry Pi, and Rockchip.
Since I'm giving up this part, I'm going to enclose my amlogic-e2-procfs, made in 2016 for the Wetek case, I designed it in reverse engineering, with the official module of Wetek, and under IdaPro : MEGA
You will be able to count on months, to publicly publish the work, as well as the source code of the addon LiveTV under Kodo, to integrate the Skin OSD of VDR.
