MP2-Setup-10th_AE_Update_1 LAV/DXVA2 performance problem (3 Viewers)

[RonD]

Tried a few more codec options on MePo2 Win8.1 system, same test video for all tests. I removed LAV since MePo1/2 would fail over to LAV.

Added 2 pngs MePo1Snip/MePo2Snip snipping tool view showing TaskManager/LAV/ProcessExplorer running MePo1/2.

Without LAV, system has 3 TV mpeg2 options
CyberLink Video/SP Decoder (PDVD10)
CyberLink Video Decoder (PDVD10)
Microsoft DTV-DVD Video Decoder

played with GraphStudio at get the following results building graphs by hand
GraphStudio > CyberLink Video/SP Decoder (PDVD10) > VMR9 (works)
GraphStudio > CyberLink Video/SP Decoder (PDVD10) > EVR (works)
GraphStudio > CyberLink Video Decoder (PDVD10) > EVR (works)
GraphStudio > CyberLink Video Decoder (PDVD10) > can't connect to VMR9
GraphStudio > Microsoft DTV-DVD Video Decoder, can't connect in/out ports to anything

MePo1 results

reinstalled LAV and get the same performance results as 1st posting. MePo2 does not enable DxVA and has higher overhead.

in MePo2/LAV, pressed F10 to "show stats", see MePo2F10.png. Also tried all 3 F11 options, same results. Does MePo2 have an option to switch between EVR and VMR9? I could not find a setting to switch. The MePo2 stats look like the MePo1 video stats when I was using VMR9.

This could be a dumb question, but I wondered whether the use of the CoreCC parser which I saw in your TsReader logs could have anything to do with it.

 

[RonD]

I removed CoreCC from both video/tv postprocessing, unregistered the CoreCC, rebooted to take that out of the mix.

Also had to disable "Enable CC subtitles" in MePo Config > TV > Subtitle Settings. I kept seeing MePo1 log entries with CoreCC removed and "Enable CC subtitles" enabled.

I've just tested it on my DevPC, 720p50 live TV:

CPU: i5-2500K @3.3 GHz
Graphics: AMD R7 200

MP2:
LAV: "DXVA2 native" : Available, Active decoder: avcodec, CPU (MP2-Client.exe): ~20%
LAV: "DXVA2 copyback" : Active, Active decoder: dxv2cb, CPU (MP2-Client.exe): ~6%

GraphEdit:
LAV: "DXVA2 native" : Available, Active decoder: dxva2n
LAV: "DXVA2 copyback" : Active, Active decoder: dxv2cb

Interesting finding in GraphEdit:
if you have "VideoRenderer" in graph, LAV switches back to "avcodec".
once you replace the renderer with "EVR", readd LAV, it shows "dxva2n" again.

MP2 uses EVR with a "custom presenter" (CP) (which passes video frames back to MP2 for rendering). As LAV seems to detect renderer capabilities it could mean that our CP causes a fallback in decoding capability.

For now users should select "DXVA2 copy back" as decoder until we found the reason for this behavior.

I also can confirm the different LAV dialog appearance: when running from MP2, it looks like old visual style, graphedit gives "modern" look:
MP2:

GraphEdit

Maybe also the MP2 MainForm initialization leads to use of some kind of fallback rendering?
@Developers any idea where this comes from?

Quick question for noob lol

What is the KEY to control pause/play/skip/stop etc. from keyboard when watching fullscreen video (even non fullscreen lol). ?

I hope MP2 will get better and better, on my side on each try that not a fully yes for now but i hope i will change my mind

 

[morpheus_xx]

What is the KEY to control pause/play/skip/stop etc. from keyboard when watching fullscreen video (even non fullscreen lol). ?

If you have a MCE keyboard (or a MCE remote) with those keys they work Pause/Resume works with [space]

 

[Sebastiii]

So no way for now to use standard keyboard ?
Sorry to be offtopic but i have made some compare test between MP1/MP2/XBMC so i was using keyboard etc. lol
Thanks

 

[morpheus_xx]

Still offtopic: at least MP2 is fully controllable with mouse, which is a big advantage over MP1. And since last release it is also TOUCHable With MCE remote support, who needs a keyboard?

But back to topic, any ideas? I thought that maybe the custom EVR presenter might be a cause, or the defined input capabilities of the IN pin. But comparing the pin config of GraphStudio graph and MP2 gave same result.

 

[FreakyJ]

Short answer why keyboard is important
My Imon remote acts as a hid device and for some buttons it only sends e.g strg + e to open the epg
So for my htpc it would be important

Bottom line for my test system Laptop: CPU = IvyBridge, i3-3237U 1.90 GHz, 2 core 4 thread, Intel HD4000 GFx Win8.1. DXVA(copyback) is worse than no HW acceleration. Copyback is about CPU = 75-80%, AVCODEC is about CPU = 45-50%.

Test video is 1080i 1920x1080 about 17 Mbps, My USA ATSC channels are between 17-7.4 Mbps 1080i or 720p. depending on network and number of ATSC subchannels.

Discovered that Msft Process Explorer (google for download) can show a little more detail on GFx engine and shows 2 GFx engines on my HD4000 system. With Msft Process Explorer, View > System Information brings up performance charts. Select GPU then Engines to see per GFX Engine chart. Hover mouse over chart to see numbers. Attached png shows output for MePo1 LAV/DXVA(native) active.

Not sure what GFx5 GFx6 really do. Looks like GFx5 handles MePo1/2 GUI activity and video. GFx6 is active when HW acceleration running.

Just windows plus 3 perfmon tools, CPU = 5-10%, GPUz = 0%, ProcExpGFx Eng5 = 2-5%, Eng6 = 0%. Each perfmon tools uses 2-3% of CPU. TaskManager, ResourceMonitor, ProcessExplorer, GPUz.

Start MePo1/2, fullscreen, idle GUI in videos window, LAV = not active, CPU = 10%, GPUz = 60-70%, ProcExpGFx Eng5 = 60-70%, Eng6 = 0%

MePo1, CPU = 45-50%, GPUz = 64%, ProcExpGFx Eng5 = 65%, Eng6 = 0%, LAV = none/AVCODEC
MePo1, CPU = 15-20%, GPUz = 60%, ProcExpGFx Eng5 = 60%, Eng6 = 20% LAV = DXVA2(native)
MePo1, CPU = 50-55%, CPUz = 65%, ProcExpGFx Eng5 = 65%, Eng6 = 10%, LAV = DXVA2(copyback)
MePo1, CPU = 45-50%, CPUz = 70%, ProcExpGFx Eng5 = 68%, Eng6 = 12%, LAV = DXVA2(quicksync)
quicksync has Audio/Video sync problem

MePo2, CPU = 55-60%, GPUz = 90%, ProcExpGFx Eng5 = 90%, Eng6 = 0%, LAV = none/AVCODEC,
MePo2, CPU = 55-60%, GPUz = 90%, ProcExpGFx Eng5 = 90%, Eng6 = 0%, LAV = DXVA2(native), LAV shows AVCODEC
MePo2, CPU = 75-80%, GPUz = 97%, ProcExpGFx Eng5 = 97%, Eng6 = 12%, LAV = DXVA2(copyback)
MePo2, CPU = 55-60%, CPUz = 96%, ProcExpGFx Eng5 = 96%, Eng6 = 12%, LAV = DXVA2(quicksync)
