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

[FillR]

Hi,

Symptom: Dynamic Refresh Rate is not adjusted correctly for some (specific ones) of my video files.

After investigations, it appears that the problem is linked to MP Infowrapper not detecting the file framerate (set to zero). This has been reproduced on MP 1.4.0 and MP 1.9.0.

Is there any way (or any patch) to help MediainfoWrapper to get the correct framerate ?

Thx

Is there any way (or any patch) to help MediainfoWrapper to get the correct framerate ?

Have you tried updating the MediaInfo.dll in the MediaPortal install directory with the MediaInfo.dll from the version of MediaInfo that you tested with?

Thanks for the tip, using a very recent mediainfo.dll (0.7.76.0), the framerate (29.97) is correctly detected by MP.

Unfortunatly, MP crash when trying to read the video.

This issue, is knowed ?
i do'nt know, i remember this ! can you try to update to last MP version ?

 

[mm1352000]

Make sure you use the 32 bit version of MediaInfo. MP is 32 bit software. Therefore it uses the 32 bit MediaInfo DLL, even when the OS is 64 bit.

You're right, need to use the mediainfo_x386.dll renamed to mediainfo.dll.

Anyway, it doesn't solve the problem, nor by upgrading to 1.12.0...

Please post fresh log files so we can see the current state of the issue. In other words, we would like to see that MediaInfo recognises the frame rate correctly, and that MP acquires that information and uses it to attempt to set the frame rate.

1) Here are the logs in 1.12.0 (files not prefixed)



2) The point is that it works perfectly with an other file very similar (same framerate), see logs prefixed by Other File OK:

Could be the "Frame Rate Mode" which is defined as "Variable" in the file that is not parsed properly as this parameter is defined as "Constant" is all my other .mkv...

 

[mm1352000]

The log file still shows the frame rate detected as zero:

MediaPortal can't adjust the refresh rate correctly unless and until you can get a version of MediaInfo that can properly detect the frame rate. Alternatively, if the frame rate really is variable... well, what refresh rate do you expect MP to use?
