MP1 EVR Presenter/dshowhelper community development (2 Viewers)

[peque]

Hello,
I'm currently testing 55c and it looks very good (without reclock for the moment). I have the best results I ever had (tested version 37 a long time ago, and MePo audio renderer version too).
Question: what is the influence of the video codec? I did a test with a mkv file (Avatar 1080p) and I have better results with ffdshow DXVA than with ffdshow "only". The green and red lines are parallels in both cases but the green line is more straight (less little waves) with ffdshow DXVA.
Thanks

All pieces in the render process affects the result, obviously. Your findings are the expected... ffdshow DXVA is using hardware acceleration, while standard ffdshow doesn't... that's why you allways (99% of the tests) will get better results with the first of them.

If you are in Win7, try Microsoft H264 decoder, and in any case, try also Cyberlink PowerDVD 10 from SAF 5.00 Unlocked, or try CoreAVC. You'll see probably different results.

bye!

Thanks Thanks Thanks... Optimizing my PC, helped a lot. Now the Rendertime and also FPS are much flatter... (v67)

Happy for you so just for you this is my very little exe to change dwm priority to real-time, I use it during the PC startup. (Others, if you think that it's a stupid idea... just don't use it)

Thanks. I was googling to see the way to fix dwm.exe to realtime...

I've modified all priorities, but I don't think this has much effect if you have your HTPC clean of unwanted processes... any comment about this?

If you want to play around with process priorities etc I'd also take a look at Process Lasso, the Windows process priority optimizer!

Thanks but too late ^^ I already wasted a lot of time to find a tool for setting DWM permanent to realtime... very very straining..

But i found "Process Lasso" which works perfectly for me

In my opinion, it helps alot... At the beginning i only had dropping frames, stutter and spikes... Then I set the priorities like technick posted befor and afterwards everything was flat

Just a thought.

If setting priorities is truly having a major influence on the preformance of MP and playback. I think the MP devs should do something about it. When MP starts, autochange these. A new FEATURE.... LOL
Maybe this can be kicked into a discussion at IRC by someone? IF its truly a big influence ofcourse. I cant judge that.

Interesting, I'm going to test it to see if it makes a difference for my config.
Thanks Technick.

Thanks Technick.

In fact I already had your suggested settings for the priorities of MePo client and server.
I was to "High priority" for DWM and changing to "Realtime" doesn't change anything in my case.
I also tested to stop my antivirus (Avast free edition) and the result is good, the green line is more straight.

Hi there,

With any AV - its best to configure it correctly.

I have it set to exclude timeshift areas (and all media areas) - I have disabled all the P2P, email,etc type scanning as I dont do that on my HTPC.

Hey, I'm wondering if the files here can help solve my problem as documented here:

https://forum.team-mediaportal.com/general-support-51/watching-recorded-tv-ts-files-pauses-freezes-mediaportal-exacly-one-minute-94947/


Basically while watching .TS recorded TV, the video will pause for exactly one minute, while the audio continues. Then the video does this fun 32x fast forward to catch up to the audio. It does this every 5-10 minutes, at random.

These files play fine in VLC or Media Player Classic. I've tried every codec in MediaPortal to no avail. I have CoreAVC and just upgraded to 2.5.1, but the TS files don't use CoreAVC.


EDIT:

Ok, so w/o knowing what I'm doing, I replaced the dshowhelper.dll with the version on here, v0055a. Instead of locking up, MediaPortal just plain crashed at the following address (I fired up visual studio):

05DEC31D mov ecx,dword ptr [eax]

I'm guessing no one reads assembly.

I tried switching the renderer from EVR to VMR9. Not only did it look worse (jerky, slow) but it crashed as well. MediaPlayer just doesn't like .TS files!
