MP 1.9.0 RefreshRateChanger AdaptRefreshRate: unable to guess framerate (1 Viewer)

[FillR]

Hi mm1352000,

Mediainfo.exe detect the file with a framerate of 29.97 and a Frame Rate Mode of Variable as seen below:

But MP 1.12.0 don't seems to get the info as mediainfo for the framerate, set equal to zero:

So, I assume MP is processing the framerate info provided by mediainfo.dll and set it to zero, maybe because described as "Variable".

Anyway, it's not a big deal, as it seems I've only one file of this type...

 

[mm1352000]

MediaPortal should detect the same frame rate as MediaInfo.exe if the version of MediaInfo.dll matches MediaInfo.exe. That's why I suggested to replace/update MP's MediaInfo.dll.

What version of MediaInfo.exe are you using?

Here is the log with the last mediainfo dll (v 0.7.7.76) as you can see:

Here is the mediainfo screen for the same file with the same mediainfo version:

My view is the MP MediaInfoWrapper code must be checked to see how the framerate is being parsed by MP after reception from mediainfo.

 

[azzuro]

maybe because is set as "variable" ?
with an other file ? is set as variable too ?

 

[FillR]

Hello Azzuro,

That my opinion as it works perfectly with "Constant" files.

 

[mm1352000]

@FillR
I have three points/questions.

1. For this file, MediaInfo is somehow detecting that the original frame rate is 29.97 fps. AFAIK original frame rate is a different property/field compared to the normal frame rate field that MP looks at. That is why MP does not recognise the information.

2. It is clear that the frame rate of this file is variable. Therefore, I previously asked (last post on page 1): what refresh rate do you expect MP to use?

3. If MP uses the original frame rate detected by MediaInfo, I think it is possible that frames would be dropped. Do you want it to use that frame rate regardless of dropped frames?

 

[FillR]

Hi mm1352000,

1) I've used ffmpeg to check the framerate, it's also detected as 29.97:

2) So I imagine it's the framerate that should be used, meaning played at 60Hz on my TV rather than the actual default (which is 50Hz for me).

3) Anyway, as I said, seems I've only one file of this type (maybe badly encoded), so it's not a big problem, I'be played this file in 50hz and in 60hz and I hardly notice any difference or dropped frames even during camera movement.

I have the same problem that MP fails to detect FrameRate correctly, at lest for a year or two. As all these files of me have 24 or 23,976 I set up a rule for dynamic refresh changer for 0=24 Hz as a workaround. My eyes are picky as I see the 25/24 jitter immediately that drives me crazy

If I remux these mkvs in mkvToolNix with manually assigning FPS 23,976 (24/1001) to the video stream, MP detects them correctly. Interestingly if I check the mkv headers I see no difference (this info is stored somewhere else)

Mediainfo states correct FPS as constant for these files. Maybe I give the mediainfo dll a shot...

 

[HakanThn]

I had the same problem with a lot of BD Movies i just encoded to mkv with handbrake. MP can't detect framrate for most of them, but mediainfo clearly states constant framrate 23,976.
I solved it by changing the mediainfo.dll as suggested above. Turns out that the version installed by MP was 7.69 which is over 2 years old. Replacing it by current version 7.87 and all mkv´s are properly detected.
Is there a reason why the mediainfo.dll is not updated to latest version in installer? or maybe did not get properly updated. I´m now on MP 1.15.
