I start to wonder if Intel is going to be a useful HTPC platform for 3D going forward:
1. The 3D Mode (for HDMI 1.4) in Windows 10/11 Display settings is gone in newer platforms (tested j5095, N95,i1235u).
2. The Intel Media SDK on first glimpse does not seem to have MVC anymore from 2021 on (i downloaded the 2018 and 2021 versions and couldn't find the libmfx files in the 2021 version anymore).
I checked my trusty AMD 5600G system again, and in summary (details below):
PotPlayer does nicely play 3D MVC with HDMI 1.4 output. So it should be possible to configure it as an external player in Kodi for now.
The old Kodi 18.2 MVC build from @
hdmkv shows MVC and 3D Mode work, but it is not really useable.
Alas, i couldn't get any MVC decode from @
damagedspline builds ;-(
Here are the details of those three options i saw, latest 2023/05 AMD display drivers and BD3D mkv file:
1. Kodi 18.2 MVC build
MVC decode with side-by-side display works fine when playing from beginning. Selecting DXVA vs. Software and DXVA2 acceleration or not seems to make a differences. With DXVA/DXVA2, CPU is at about 13%, GPU at 10%, with Softare only, CPU peaks at 30%, GPU stays at 7%.
Problem: When jumping to some position in the file or restarting to some position, the picture becomes very jumpy. Looked at it side-by-side without 3D decoding by TV, it seems the right eye is jumpy, and the left eye may range from correct, to some flashes to also being jumpy. Also depending on what Decoding option was choosen. Aka: can not jump into movie position. Does also not correct itself over time.
HDMI 1.4 Hardware based playback will work if it is enabled from Windows Settings, and Kodi is run windowed. You may also need to resize the window after playback starts just a bit to kick in 3D decoding. When finishing 3D playback though, GUI is messed up thought.
When you go to fullscreen (fullscreen window or not) with HDMI 1.4 Hardware based placyback, assist playback, AMD driver may crash or picture turns dark, or crap is displayed.
2. MVC builds from @
damagedspline
With both an 19.4 build and the latest 20.1 build, i fail to get any MVC decode, even with just side-by-side display. When i select DXVA, i get black picture, when i select software, i do get only 2D (both eyes same). Independent of which MVC decoder level i select. Of course, i have not tried all combinations of 0...35 decoder level and DXVA/software/DXVA2, but quite a few.
So, given how the 18.2 does already do a pretty good job, i wonder if maybe some of the newer system libraries with which @dmagedspline may have built the 19x/20x MVC may be at fault or maybe need to be called with e.g.: lower DXVA versions or the like..
3. Potplayer
Works out of the box:
Download from
https://potplayer.daum.net/.
- "3D Video Mode settings" -> "Enable H.264 MVC 3D Decoder" [X]
- "3D Video Output (Screen)" -> "Stereoscopic 3D (Windows 8)"
(That is frame packing / HDMI 1.4 FullHD 3D).
- Likely need to also download OpenCodec for audio to work, but
no need for ffmpeg or libmfx library install.
