I recently setup a shield 2015 with kodi. I have noticed that home widgets in the default Estuary skin don't update. I refer to the "Recently added movies", "In progress movies", "Random movies" sections in the movies Home menu. When, for instance, I stop a movie half way through and I go back to the home menu, nothing updates. But if I exit Kodi and open it up again, then the widget is updated and the movie appears correctly in the "In progress Movies" widget. the same happens when I scan new items in the library, they don't get updated in the widgets unless I exit/enter Kodi again.

First time I use the default skin (always went to other alternatives such as Aeon Nox) but I wanted to keep Kodi as basic as possible. Is this the expected behaviour? Any tricks to update them?

Thanks,

I had used an incorrect pattern file for 10-bit and that was probably causing the errors for 10-bit YCbCr 4:2:0 output. Now the output is accurate for 8 & 10-bits. There are still some small differences between Kodi and Photos & Videos output.

Thanks so much for posting this! I've observed various issues with Shield TV's 4K BT.709 output for some time, but haven't had the opportunity to measure it myself.

Question related specifically to the above statement. I see color space errors on a 2K YCbCr 4:2:0 8-bit BT.709 pattern with Shield TV upscaling/sampling to 4K YCbCr 4:4:4 8-bit BT.709 and 4K YCbCr 4:2:0 10-bit BT.709 (using Photos & Videos primarily). Since you're measuring those color space outputs to be correct, I'm wondering if I may be doing something wrong similar to what you did back when you saw errors for YCbCr 4:2:0 10-bit BT.709. Do you mind elaborating how the pattern was incorrect?

Do you mind elaborating how the pattern was incorrect?

I had edited the SEI of the test pattern file and forgot to put back the primaries/matrix/transfer details. Apparently, Kodi has issues with that. It looks like it may be defaulting to BT.601 matrix coefficients for RGB to YCbCr conversion. Setting the output color space to RGB will help confirm whether that is the case or not. I will check it out when time permits.

OK, well, that would not be the problem I'm having. Good information to know just the same. Thanks.

Yep. RGB is correct. Just the YCbCr selections are mangled. Curious that they would use the correct matrix for 2K output, then fall back to BT.601 (or something) for 4K.

I look forward to your results, time permitting.

I brought up the matrix issue only to explain the odd results that I got with my test pattern that didn't have proper SEI data. I haven't come across any problem with 8-bit 1080p content to 4K upscaling or chroma upsampling.

I noticed something weird on the shield, tv episodes with a colon, question mark, etc do not scrape. It works fine on my LE NUC and and I use TVDB, is this a bug? Only reason I found this is because I noticed episodes missing and that is all I see in common with the missing episodes

[Tinwarble]

Nothing to do with the Shield, it's the same scrapper no matter what OS or device Kodi is running on.

I'd suggest you review the naming convention for TV shows in the Wiki http://kodi.wiki/view/Naming_video_files/TV_shows

[briand095]

so TVDB is wrong then, which the files get named by, no matter, I guess it seems to be my fault/problem to deal with

What is the show? Which episodes?

Usually TVDB has alternate titles that can be used.

Just for the record, I haven't found a solution to this issue but a work-around in my setup. I configured my harmony remote to Quit Kodi each time I change activities. When I come back, kodi starts again and widgets are refreshed.

In case someone else find the same problem.

are you using a hdfury+dvdo tpg to do this?

No, Astrodesign VA-1842 analyzer. You can't use the DVDO TPG, it doesn't support 10-bit 4K 50/60Hz YCbCr 4:2:0.

I thought something was amiss..

I updated my original post. I was using an incorrect pattern file for testing YCbCr 4:2:0 output. Now, it looks like 8 & 10 bit outputs are accurate. However, there are some insignificant differences between Kodi and Photos & Videos outputs. Based on these tests, I wouldn't advise anyone to use Shield's 12-bit output mode. It has errors that may be noticeable.

..so thanks for confirming

Are you saying that that your test file is RGB encoded, or am I reading this wrong?

[wesk05]

Are you saying that that your test file is RGB encoded, or am I reading this wrong?

No, it is YUV/YCbCr. Apparently, Kodi needs information about the color space. Without that information, it seems to default to ?601 matrix for RGB -> YCbCr conversion. I guess even for Mediacodec (Surface) rendering Kodi does YCbCr ->RGB ->YCbCr conversions. I could be wrong about this, but the output was certainly messed up with the file that didn't have defined primaries/matrix/transfer.

I have two sets of 10-bit files. One for HDR and another for 4K Rec.709. When I made those changes, I forgot to put in the SEI/VUI details.

[timstephens24]

What about 8-bit Rec.709 playing with the Shield set to 10-bit Rec.2020 (YCbCr 4:2:0)?

That is not a setting that I would suggest for the Shield. While the luma is fine, there are huge errors in chroma. Previously, I had assumed that Shield merely up sampled 8-bit to 10-bit, but it looks like that is actually not the case with chroma. I am just not sure what conversion matrix is being used for chroma. I have checked this only with Kodi 17.3. I haven't checked it with the Photos & Videos app. If it is different on that app, it would make things complicated. BT.709 to BT.2020 color conversion guidelines are provided in recommendation ITU-R BT.2087. Amlogic Nougat SDK based firmware now has HDR to SDR and SDR to HDR conversions. I haven't gotten a chance to check what those conversions look like. It looks like the work is cut out for nVIDIA.

Well, sorry if was already discussed, an interesting info about Netflix sending 1080p content in HEVC codec on SATV link - click spoiler tag.
