Nvidia Jetson Nano, superfast Kodi device?
#16
So,.. is there any updated version of Kodi?

Because I see only Krypton available ūü§Ę

I was hoping for Libreelec but nVidia beings Di*ks and all (according some great people) I don't know where the process is going,..

I did searches and posted all that was interesting to me here

well, i tried to run kodi from this device and i must say it seems to be good (at least for someone limited to 1080p as i am right now)
i removed all the desktop stuff, made kodi start as a systemctl service and must say that (again, using 1080p-60) it runs great all the stuff i try. One big trouble i'm having is to make it bitstream dts-ma/dts:x/dolby truehd/dolby atmos, as all i get is a buzz instead of the sound. what i did was to disable pulse but really don't know how to set alsa to bitstream to hdmi
is there anyone who would will to help?

^No DRM support would be deal-breaker for some people. If it weren't for that if would really be best of both worlds.

Just a little update... I built pulse audio 13.0 from sources and now I have audio passthrough

DD/DTS (i.e. SPDIF bitrate) or Dolby True HD/DTS HD HRA or MA (i.e. HD Audio)?

Truehd and dts-ma (really atmos and dts:x), and it seems to work as expected

That's encouraging. Is the video decode hardware accelerated or CPU?

no, it's done in software, but 1080p is really smooth
kodi cpu was 200%, but thinking it's a quad core it's not so much

1080p in which codec and at what bit rate and frame rate?  5Mbs 1080p24 h.264 is quite a bit different to 20Mbs 1080p50 h.265 for instance.

ok, i just tried some demo files for atmos/dts:x, anyway i found here that there is an accelerated version of ffmpeg for nvmpi, so i built it and built kodi with that ffmpeg. Of course, as there is no renderer for nvmpi, everything still runs in software mode, but i guess someone with more knowledge than me could write a renderer to use the nvmpi accelerated ffmpeg

Sorry for being late on the party, doesn't seems to be hot topic anyway Smile 

I did some work on hardware rendering on Jetson. Runs 4k @ 60 fps up to 140 Mbps. *source code URL removed by moderator. See next post*
If someone is interested to help testing - would be much appreciated.

Oops, wrong branch.

Here is correct link to Source code

I've got a Jetson Nano sitting in a corner - if I get a chance I'll give it a go!  Thanks for sharing.

Are you able to advise a bit more on build process - particularly what CMake configuration you used (GL vs GLES, X11 vs Wayland vs GBM etc.)

Also how do you build/install libshairport?

Hi, thanks for giving it a try!

Jetson only have GLES support, and this particular rendered is for X11. I haven't tried GBM yet. CMake settings I used: 

Code:

-DCORE_PLATFORM_NAME=x11 -DX11_RENDER_SYSTEM=gles -DENABLE_INTERNAL_FFMPEG=ON -DENABLE_INTERNAL_FLATBUFFERS=ON -DENABLE_INTERNAL_FMT=ON -DENABLE_V4L2=ON -DENABLE_NVBUFFER=ON 

I installed most of dependencies from APT repository following Kodi guide. As per libshairport - you can install it also from APT. However, i think you had libshairplay on your mind.
I don't have it installed, and build works fine without it. You can try compile it from source.

There is a way, how Kodi build system compiles it. Seems like straight forward ./configure && make && make install process.
