Req NVDEC (NVDECODE API) support in Kodi to decode 4K/8K 10-bit/12-bit HDR on Linux?

AFAICT, the current sentiments towards Nvidia's latest graphics driver jamboree in Linux have not changed.

Moreover, the shrunken number of developers in Team Kodi in the last 1.5 years gives us really no luxury of taking up additional work.
Sadly we cannot just open up a can of fresh Kodi developers and put them to work just like that. It is what it is.

I use an Nvidia graphics card myself in Ubuntu Linux, so I feel your pain.

FYI; FFmpeg 4.2 (codename "Ada") was released on August 5th in 2019 and among other things added; Support for HEVC 4:4:4 content in nvdec and cuviddec

Interestingly, in off-topic but in somewhat related news (not for this thread); FFmpeg 4.2 version also added; Support decoding of HEVC 4:4:4 content in vdpau 

Still no news about NVDEC NVDECODE (FFmpeg cuviddec) support in Kodi?

There have been some changes in the last couple of months which is encouraging. I would like a proper Nvidia video support in a Linux desktop environment, such as Ubuntu which I use as my daily driver in an "office pc". Hopefully one of the LTS 20.04 distros will provide some more possibilities there. AMD probably will be in a next PC setup for me.

In LibreELEC, the chunk of Nvidia users is getting slimmer each time. The uncertain future of Nvidia support isn't helping. It's mostly about the cheaper Raspberry Pi and Android-type box solutions running LibreELEC. I'm not using a full-blown Nvidia HTPC at this time, and I doubt I will do that again. Intel has gained the best seat there.

Ok, with regards to Libreelec. I think we can safely say Nvidia is on its way out. I'm running an old desktop with an Nvidia 1050.

I can swap the display cards out but the question is to what?

I've tried an AMD RX550 card but got nothing but headaches. No acceleration at all on anything.

Any suggestions?

No offence but please start a new thread for that question any other off-topic discussions so not to threadjack this thread to discuss other solutions.

@Klojum NVDEC support in Kodi's FFmpeg might be of more interest to developers now that Nvidia launched this new budget NVIDIA Jetson Nano 2GB single-board computer devkit for only $54 (or $59 with a Wi-Fi USB dongle)?

Biggest difference the NVIDIA Jetson Nano and a Raspberry Pi 4 is the more powerful Nvidia GPU in the Jetson Nano and game emulation with RetroPlayer is another reason for wanting it instead.

https://www.cnx-software.com/2020/10/06/...loper-kit/

A similar but beefier and slightly more costly NVIDIA Jetson Nano Developer kit with a 4GB RAM SBC that also has DisplayPort, more USB 3.0 ports, an M.2 Key E socket, PoE support, plus one additional CSI camera connector was introduced in March 2019 for $99 US:

What are the reasons today for not building Kodi's FFmpeg with NVIDIA NVDEC and CUDA support enabled?

https://forum.kodi.tv/showthread.php?tid=327755
 
Noticed that Kodi 19.x "Matrix" Alpha 1 has already been upgraded to use FFmpeg 4.3.1 (FFmpeg 4.3):

https://github.com/xbmc/xbmc/pull/18166

https://github.com/xbmc/FFmpeg/

Not that FFmpeg version should matter as FFmpeg 4.0 could be built with nvdec support?

Any news about enabling NVDEC support in ffmpeg builds for Kodi/XBMC?

Noticed that FFmpeg 4.4 release now also mention "NVDEC AV1 hwaccel"

https://git.ffmpeg.org/gitweb/ffmpeg.git.../Changelog

By the way, FFmpeg 4.4 mention VDPAU accelerated 10-bit and 12-bit decoding as well

"VDPAU accelerated HEVC 10/12bit decoding"

"VDPAU accelerated VP9 10/12bit decoding"
