MP1 EVR Presenter/dshowhelper community development (3 Viewers)

[cfforce]

I also have many dropped frames / stutter, in a high end system (ATI 5870) & Atom-ION; and the cause was IFC (https://forum.team-mediaportal.com/...ction-2-0-beast-unleashed-81898/#post615649); if i run MP in debug; or disable only IFC; dropped frames are gone.
Using V12 atm; and all is looking good! (IFC-Disabled)

i tried this version too but it doesn't solve the crash problem... if you want I can try to save a log..

I never tried v010 and v011 because with those version I receive a lot of stutter...

OK, thanks - don't bother with the logs, I'll post another dll version to try later.

Have you tried my v002 or v004 versions ?

mironicus/grubi/cecet23 - can you try the attached dll please - I've modified the vsync correction behaviour when the display/video fps ratio is not an integer multiple e.g 60Hz/24Hz, and rolled back a recent change which might be causing the crashes.

cecet23 - were you getting any crashes with v0010/v0011 dll's ?

jet70 - I think Tourettes comment about 23.976 <-> 24Hz video/display issues is probably the problem - if you can't set the display to 23.976 then use ReClock to pull things into sync.

Tony

No still the same problem.
The source is 24fps and display refresh rate is 50Hz.
I know it is not optimal, however the original DLL handles this quite well.

Hi Grubi,

Please try the attached dll and report back.

yes... I used v002 a lot of time since rc3 (with reclock), without problem...

OK - so the bug has been intoduced after v002.....thanks for the info.

However, the Actual frame rate line (red line) seems to glitch every 40-45 seconds causing temprorary stutter. The picture recovers and then does te same thing again after another 40-45 seconds. This continues with this pattern and frequency.

Anyone got any ideas? The fact that this occurs with a regular pattern suggests that maybe something else external (a background windows function/event) might be causing it or could it be the dshowhelper dll?

Either:

1) audio HW's and GPU's hardware clocks aren't running in sync (small drift is happening with all HW...)
2) source fps doesn't match the display Hz - 40 second drops are quite close to the 23.976fps played on 24Hz display (in any case are you using Intel i5/i7 CPU's GPU that is known to not to support 23.976hz, at least with the available drivers)

Both are issues that cannot be fixed with EVR presenter alone.

Thanks Tourettes and Owlsroost,

You are both correct. After tampering for a couple of hours - I just couldn't get the ATI CCC to offer me the option of 23Hz initially but eventually got it to appear.I have managed to get rid of the 40 second glitch by setting the refresh rate to 23hz (23.986). The stutter/judder has been overcome with these new dshowhelper dlls and the glitch has been fixed with the correct frame rate.

Thank you so much. The dll looks good - I am currently on V14 and will try V16 and extend my testing. My very troublesome h264 and xvid test files are now looking good for the very first time. I can now try a broader set of files.

Excellent job!

You cannot set 23 Hz within the Catalyst Driver - it will always change to 24 Hz - it is a known bug.

Just insert "23" into the Mediaportal setup of the dynamic displayrate changer and you'll get want you want - 23,976 Hz.

Changing the refresh rate within the Windows 7 resolution changer advanced options works fine though (just right-click on the desktop).

ATI users also need to disable GPU scaling to get the option to switch to 23 Hz - as long as GPU scaling is enabled you won't see all the native supported refresh rates of your TV selectable in the menus (seems to be another bug).

Re: AW: MP1 EVR Presenter/dshowhelper community development

That's interetsing mironicus - thank you.

However, I tried it in Windows 7 resolution changer and couldn't find it in there either?! - infact I had to dig a bit to find options to change the refresh rate ....

I have GPU scaling enabled, and it seems to be behaving at the moemnt, but I will double check my settings when I get home from work.

Thanks again.

Didnt know it was a known bug of CCC. But I found after manually setting the RR to 23 from within Windows itself in the advanced tab (not the CCC) and pressing YES, it actually wants to switch to the refreshrate 23.9xx. Otherwise it goes to 24 automatically. Atleast I think this made it go for me.

Hi.

Latest 12,13 & 15 work absolutely fantastic, with ReClock doing only Audio slow/speedup.
No dropped frames, no matter what I throw ty Ge84000, full fps all the time.

Br,
