[fixed] 4k HEVC DXVA2 not playing correctly in MP2 (1 Viewer)

[Owlsroost]

Question - which versions of HEVC play OK using 'DXVA2 Native', and which don't?

Do 4k 8-bit work?
Do 4k 10-bit work?

If it doesn't work 'native', does it work 'copy-back'?

(I'm guessing that LAV Video decoder can't negotiate a usable DXVA2 connection type for e.g. 10-bit HEVC through MP2's EVR presenter. Does MP2 handle 10-bit video OK using other codecs e.g. H.264?)

The file I am testing with is 10 bit HEVC both native and copy back do not work with MP2 but work with MPCHC. I am going to look for a 4k 10 bit H264 and 8 bit HEVC file for testing.

I remember that DXVA was initially (4 years agon) not working because the service was not returned here: MediaPortal/MediaPortal-2. Are there more services required to make it working?

x264 4k 10 bit works
HEVC 720P 8 bit works

Still looking for a HEVC 4k 8 bit file to test with.

HEVC 4k 8 bit has no video.

I don't think so (but it's been a very long time since I last worked on MP1's EVR presenter).

HEVC 4k 8 bit has no video.

What would be interesting is to compare (using Graphedit) the connection information on the LAV Video decoder output pin for the HEVC files that work OK with the ones that don't (just double click on the filter to open the properties window):

The screen grab above is from just opening an 8-bit HEVC file directly in Graphstudio, and it's not using DXVA.

I might be looking for the wrong thing but where do you see if its using DXVA in graphstudio? I did notice graphstudio is not using hardware acceleration in LAV which may or may not matter for the info you need.

4k 10bit HEVC (not working in MP2)

4k 8bit HEVC (not working in MP2)

720P 8 bit HEVC (works in MP2)

4k x264 (works in MP2)

I have a few more wrenches to throw into this.

Some files do have limited ability to play in MP2. Below is a 4k HEVC 10 bit file that mostly works in MP2. MP2 stutters and gets out of sync with audio during complex scenes and will not skip ahead or resume after being stopped, it just freezes with a blank screen. This particular file is 17.8Mb/s and 24 minutes long vs a regular movie I was testing in the other files. The non working file is 128 minutes long 44.3 Mb/s.

Mediainfo for working file top and non working bottom. Both files work fine in other programs like MPCHC.

4k x264 (works in MP2)

The screen grabs below that line look like they are for a 720 x 480 frame size file, not 4k (look at the 'rcSource' and 'rcTarget' values).

I might be looking for the wrong thing but where do you see if its using DXVA in graphstudio? I did notice graphstudio is not using hardware acceleration in LAV which may or may not matter for the info you need.

In theory, the 'biCompression' value should be 'DXVA' - but if you have the sys tray icon enabled for LAV Video and use it to open the property page it will tell you which decoder is in use ('Active Decoder: dxva2n' in the example below - it will be 'avcodec' if it is using software decoding):

I think there may be some confusion here about using GraphStudio with MP2 - what we need is to use the 32-bit version of GraphStudio in 'connect to remote graph' mode while MP2 is playing a file (run MP2 in windowed mode to make this easier). That allows you see the live graph that MP2 is using. Example using MP1 below (note 'biCompression' = 0x61767864 [dxva]):

To make the remote connect work, you need to drop 'proppage.dll' (attached) into the same folder that 32-bit GraphStudio is installed, then open an administrator command prompt and type "regsvr32 proppage.dll" to register the dll. Then run GraphStudio and select 'Connect to Remote Graph...' from the file menu

This is playing a 4k HEVC version of the movie (in MP1):

Yep, I definitely wasn't using graphstudio right.
