So my setup is HTPC running Kodi 16.1, then using UPNP to either FireStick or Fire TV2 streaming certain HEVC movies from the HTPC to either stick or FireTV2 results in jittery movies as in the system cant keep up. What is weird is that this is not on all HEVC encodes just a few. Also, I dont really see any other issues, with MKV, MP4 and such, streaming is fine. The movies plays fine on my HTPC. Any ideas on what could be happening? It is not a 4K encode just 1080p. Thanks for any help or suggestions.

I think your right, probably not able to do 10bit properly

I dont understand this enough, but I guess 10bit is just too much. Are there any potential solutions or just limitations to the hardware? Thanks again for the help!

Everything where it is not working.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

One can init the decoder, one cannot.

The Fire TV stick can't play HEVC content for sure. No hardware decoder and fairly weak CPU for software decoding.

Thank you for the heads up. Naïve question. I know now the Fire TV Stick has no hardware decoder, and CPU sucks... would there be any hope that SPMC may be able to play them since its geared more towards android? Thank again for the information. On the AFT2 Kodi works great, streaming all my content from my HTPC, really love the work the Devs have done with the program.
Cheers

The problem isn't Kodi, it is the fact that the FireTV Stick cannot hardware decode and bad CPU, no other program/version will help make it play. To put it frankly, you are trying to cross the Atlantic with a Row Boat.
