Testing MrMC 3.7.0 - [Invites Closed]

[wesk05]

Per definition (for 4:2:0, still), 1 chroma applies to 4 luma. You don't "upscale" the chroma, you just apply the same chroma to 4 pixels. If you interpolate those chroma pixels, you are breaking the YUV definition.

Isn't this what nearest-neighbor interpolation is?

I think I understand the confusion. The scalers (including HQ) are in rgb space, this is after any yuv conversion. So there are no changes in chroma/luma handling.

Note that these are the exact same HQ scalers found in SPMC and Kodi (for desktop).

RGB is technically 4:4:4. So, to get there from 4:2:0 you still need interpolation.

Edit: I think I now understand the confusion here. While you two are discussing the resizing HQ scalers that operate in RGB space, cosmoxl & I are talking about the chroma upsampling involved in YUV to RGB conversion. I believe cosmoxl's original question was why the GUI or debug log was showing bilinear scaling when the input/output resolutions matched. Unlike madVR, an end-user cannot change the chroma upsamling filter in Kodi.

I've made lanczos3 as default scaler and I guess it's working.

However, when 720p50/60 videos are played and 720p50/60 is output the scaler used is nearest neighbor.

I understand that no luma scaling is having to be done as the resolutions match, but there's always chroma upscaling isn't there?

lanczos3 is a HQ scaler. It operates in rgb space so I have no clue what you mean by chroma/luma upscaling.

Right. Koying replied this originally - RGB. My question is what wesk05 is thinking as well - what happens before RGB.

There always has to be chroma upscaling, and I guess I thought we had control of that too and I was simply bothered that I was seeing nearest neighbor. But, it sounds like that part of the process has always been nearest neighbor and always will be unless you take up the idea of madvr.

Sorry for the bother!

You don't have to fiddle with codecs. If "HDR display" is "No" and a HDR file is detected, MrMC will automatically fallback the AMC non-surface.

Now, ffmpeg is confused by "file.mo" (DV) and do not provide the needed info for detection. I might need a sample to see what can be done.

"file.mk" should be ok, not sure why it falls back on s/w decoding. Maybe because of the codec fiddling?
Is it the "full white" one? I could tell more with a sample as well.

Setting codecs back to default doesn't fix all problems. I'm not getting fall back to software but when I was last night I did have non-surface enabled. stuff is weird.

That's the file.mo (DV). When I played that just now surface was used instead of non-surface. Detection has been worked on a lot, I thought in core (not tvOS/iOS specific), so not sure why the problem now.

The demo file here is another one I test with. For this non-surface is used, but no tonemapping is happening.

As well, no tonemapping is happening on other HDR files I have in my collection.

Something I'm seeing is that refresh rate switching isn't happening for 4k files. It's not just HDR files as I test with Tears of Steel in 4k SDR which is 24p and it doesn't switch. But, 1080p23 are switching just fine, for example. MrMC does show 24p and 23.976p as options.

I think my reply here might have been missed so just posting it again.

For iOS:
-in the Plex add-on on my iPad 10.5 the posters are still cutting off on the sides
-in the Plex add-on on my iPad 10.5 the touch is still off in the settings area

That's about all I can text until hopefully Tuesday when I get internet hooked up.

Speaking of iOS, I sent an email yesterday to get back on the test list for iOS but testflight isn't showing me as a tester.

I asked for google play was invited to ios testflight. Should I email again or just have to wait for someone to get around to it

I'm having a problem with the itunes file sharing/local file sytem access.

There seems to be no way to specify which directory that individual files go into - TV or Movies, for example.

If you put a mix of TV and Movies into the root directory, set a TV and a Movie scraper to look at that same directory, my experience is that the TV library is removed but the Movie one exists.

Obviously I don't have to scrape and can just browse via media sources.

Or a person can organize media into folders prior to uploading to the device. But, adding new media means having to add each new folder as a media source, setting the scraper.

Am I missing any other option?
