Grey blacks with internal player + EVR (1 Viewer)

[pilehave]

Testing against my Lenovo D221 LCD monitor gives me same results as HomeY (using the files he supplied BTW). When we say "correct levels", then it means that I should only see bars 17-25 flashing, right?

With the original dshowhelper.dll I see 2-25 flashing.

SP1 evr.dll + original dshowhelper.dll == incorrect levels
SP1 evr.dll + dshowhelper_nominal_range_0_255 == correct levels
SP2 evr.dll + original dshowhelper.dll == incorrect levels
SP2 evr.dll + dshowhelper_nominal_range_0_255 == correct levels

If it makes any difference I'm only on SP1 on my Vista32 Danish.

I have Nvidia graphics (Quadro NVS 140)

Here are two screenshots with bad and good black. I think I had bad blacks before as I now think the picture is much more vivid and alive.

Bad to the left, good to the right.

Correct.

And those 2 screenshots do show a difference (especially the speaker from the guitar looks washed out!), but the only way to test it properly is with the testpatterns (which you have done).

Good to hear that also NVidia users experience incorrect blacklevels without the updated dshowhelper.dll!

I tried the 'dshowhelper_nominal_range_0_255.dll' and MP crashes almost immediately when playing the video test file - logs attached. The Windows application log entry is "Faulting application MediaPortal.exe, version 1.0.2.22555, time stamp 0x4a04b3db, faulting module unknown, version 0.0.0.0, time stamp 0x00000000, exception code 0xc0000005, fault offset 0xe8001cc2, process id 0x%9, application start time 0x%10."

This is really weird. Such change shouldn't cause any crashes. Anyone else seen this?

Yes, I have the same problem!

As soon as I start a video, MP crashes (no video/picture at all, audio continues).

I'm using Vista 32Bit Ultimate SP2 with MP 1.0.2

Video Hardware is a ATI HD 3200 (OnBoard).

My logs are attached!

EDIT: The error message in the event log seems to be same like the one reported before:
Fehlerhafte Anwendung MediaPortal.exe, Version 1.0.2.22555, Zeitstempel 0x4a04b3db, fehlerhaftes Modul unknown, Version 0.0.0.0, Zeitstempel 0x00000000, Ausnahmecode 0xc0000005, Fehleroffset 0xe8001cc2, Prozess-ID 0x%9, Anwendungsstartzeit %10.

Before this, I did try the two 'video range' settings in the nVidia control panel 'Adjust video color settings' section (set to 'with nVidia settings' i.e. override player settings) :

0-255 => correct grey levels.
16-235 => incorrect levels.

With it set to 'with video player settings' the original MP dshowhelper gives incorrect grey levels, so it looks like the 0-255 setting is the correct one.

(Vista32 SP2 with all MS update patches, nVidia 9500GT with 182.50 drivers, tried with PDVD7 & MPC-HC h.264 codecs - new dll crashes with both)

I'm not good with logfiles but what i can see in your logs is the following:

2009-07-14 09:40:45.612000 [ERROR][MPMain]: failed:unable to add filter:ffdshow Audio Decoder to graph
2009-07-14 09:40:45.612000 [ERROR][MPMain]: failed filter:ffdshow Audio Decoder not found
2009-07-14 09:40:45.639000 [ERROR][MPMain]: failed:unable to add filter:ffdshow Audio Decoder to graph
2009-07-14 09:40:45.639000 [ERROR][MPMain]: failed filter:ffdshow Audio Decoder not found

So no graph is being created because of a missing audio codec?

Tony, could you confirm using ffdshow as audio codec? If so, could you try and test the new .dll file with AC3 filter as audio codec (that's what i've tested it with)?

It looks like an audio-codec issue.


In neo2001 logs i'm seeing:

2009-07-15 01:04:14.762474 [ERROR][MPMain]: Control has invalid animation type [ on thumbAnimation] (error.log)
2009-07-15 01:04:00.948474 [Warn.][MPMain]: GraphicContext: NO screen calibration file found for resolution 1920x1080! (MediaPortal.log)

No idea what that's related to... Maybe a mod could clear some things up about the logs?

I have the same problem using a Nvidia 9400 setup on Windows 7. Washed out blacks in MP 1.0.2, while MPC-HC is fine. I use the MPC video codec with the Cyberlink audio decoder. Have tried the new dshowhelper, but it immediately crashes the player.

 

[Owlsroost]

I've tried various audio codecs, & disabling various plug-ins - MP1.0.2 still crashes every time with the modified dshowhelper.dll (and the standard 1.1.0 version) whenever it tries to play a video file or live TV.

It does get as far as building the graph (and displays at least one frame) - I checked the graph with GraphStudio and it looks OK.

Attached are log files generated in 'debug' mode leading up to a crash.

Can anyone get the modified dshowhelper.dll to run with MP 1.0.2?

On my 9500GT system, selecting 'with nVidia settings' and 'full range (0-255)' in the 'Adjust video color settings' section of the nVidia control panel fixes the problem.

So far it seems only you and me.

On my 9500GT system, selecting 'with nVidia settings' and 'full range (0-255) RGB' in the 'Adjust video color settings' section of the nVidia control panel fixes the problem.

Tony

So it seems we've tracked the problem, now a solid fix needs to be found.
I must say i'm pretty disappointed by the number of responses so far.....
Doesn't anybody bother about the most important thing of his HTPC?? PQ!!

Tourettes: Did you test it yourself? Having crashes? See any differences?
