We are exploring implementing Widevine L1 DRM with hardware video acceleration; so it's not Netflix specific per se.

Google Cast will not be supported. 
@Sam.nazarko- Have you guys figured out a way to get steam or moonlight gaming on it? If it does either of those two, I’m ditching my shield and ordering one right now!

Let me know, thx.  
There is an open issue on getting Moonlight to work with Vero 4K/4K+. See https://github.com/irtimmer/moonlight-em...issues/573
I've offered to send them hardware but they don't seem too interested.

The good news is that this testing was based on our 3.14 kernel and it may behave better with our 4.9 kernel and AMCodec improvements.
Unfortunately I don't have an NVIDIA GPU which I could use for testing easily. I'm sure we can get it working, but I don't have an ETA presently.

Sounds encouraging. How about Steam as a second option in case Moonlight is a no go at the moment? I saw some stuff about steam floating around on OSMC forums but cant seem to locate the thread anymore.

The ARM steam binaries depend directly on OMX, an interface used for Raspberry Pi hardware accelerated video decode.
As we don't have this interface on Vero4K/4K+ and the program is not open source, it's not possible to get this to work at this time

Cheers for the quick response. I will be keeping an eye on the OSMC boards then.

Updated post #1 with a quick video demo/review and photos. Hope the YT exposure will generate additional interest w/4K and 3D fans.

I'm still looking for the forum topic about widevine / 4K netflix support in kodi

Got a link?

Try this one Dolby Vision for Vero 4K+?
Sony KD-65X8505C • Onkyo TX-RZ840 • Q Acoustics F:2050i C:2000Ci R:2020i S:2070Si A:QI65C

A selection of issues:

- It took Nvidia a good four years to get it to the point where it could switch between rec.709 and rec.2020 colour spaces automatically. Even now this ability is disabled by default and you have to go into "Advanced" settings to activate it - the default behaviour is to output rec.2020 SDR.

- Inaccurate video decoding: the pixel colours in the HDMI output do not precisely coincide with what's encoded in the video.

- Terrible upscaling. Kodi can switch resolutions to match the video, but other apps can't.

- Unable to output 480p or 576p: so even in Kodi this guarantees dreadful picture quality for SD material.

- The worst chroma upsampling algorithm I've ever seen: it actually uses a nearest-neighbour approach rather than bilinear, which makes everything look weirdly rough and grainy.

- Truly horrible deinterlacing.

- The Netflix app cannot switch refresh rate to match the video frame rate, so with default settings Black Mirror (for example) will be converted to 59.94Hz rather than output at 50Hz.

- You can change the output refresh rate at desktop level, but when you go back into the Netflix app it helpfully switches the output resolution back to what it was the last time you were using Netflix! To stop it from doing this, you actually have to force-stop the app.

- No matter what you do, you can't get 4K/24Hz or 4K/23.976Hz out of Netflix: if the refresh rate is below 50Hz it won't access 4K video streams.

- No Dolby Vision output on Netflix.

- YouTube limited to 1080p/SDR.

- Can't play 4K/HLG in iPlayer.

- In Amazon Prime Video there's no frame-rate matching and (I think) it can't access 4K streams.

- No MVC 3D!!!

Really? I’m thinking of getting some kind of device for the sole purpose of getting darker subtitle colors for usb content (lg b7 oled, subtitles in hdr are blinding), so that’s bad news.

The subtitle frame-skip issue, as far as I'm aware, only affects image-based subtitle formats (e.g. PGS), and you can't change the colour of those anyway. If you're going to be changing subtitle colour then you're presumably thinking about text-based subtitles (e.g. SRT format) in which case you'd probably be okay.

It's generally only an issue on 4K 60fps stuff, e.g. Billy Lynn's Long Half-Time Walk or Gemini Man; but there's a thread that mentions it happening on Avatar as well.

Buffering issues:

When hit pause while watching a movie, when I come back and hit play it buffers. If I go back to see a scene again and then fast forward to where I was. it also buffers.

Not sure what the issue is?

I believe this was an issue with your WiFi connection and you've since resolved this on our forums, albeit by using an Ethernet cable now.
If you have any further issues please continue your post there or start a support ticket.

Cheers

On a kind of related topic, what’s the iperf3 command for outputting results to a text file? Searched online and I see --logfile can be used, so is it simply something like iperf3 <ipaddress> --logfile?

You should be able to output it to a file with > filename appended to the command.

Can you let me know your contact info? Interested in importing Vero 4K+ in South Korea. Thanks.
