MP2 - V2.1 MP2 suddenly stops working while playing audio / Crash inside FreeType (1 Viewer)

[Alan Honeyman]

Several times this morning, after playing audio for some time, MP2 fails. Perhaps this is related to TrakT as per this log message:

Hi,
what do you mean by "MP2 fails" ? Does the audio playback stops unexpectedly? Or does it not even start? Can you still reproduce this error? If so, could you please attach log files?

Regarding the trakt error, this should be fixed in a upcoming version of this plugin. Nevertheless it shouldn't have any impact on the audio playback.

 

[Alan Honeyman]

It seems to happen at the end of playing and has happened with both audio and video. Attached is an audio example. I was playing a number of tracks over maybe an hour or so when at or near the end of a track, I get a popup saying Mediaportal has stopped working. Log attached.

Looks like a skin engine + PIP problem. The client log ends unexpectedly at:

and just before this, the windows event log contains:

can you reproduce it reliably? Does it happen only while playing a video in background? After given timespan?

 

[Alan Honeyman]

So far it seems quite random. I've been playing tracks since my last message without a problem.

the event log says that freetype6 is responsible for this crash. We are using currently 2.6.3. The latest version is 2.9. Can we just update to this version or are they any other dependencies/components we would have to update/adjust too?

Hi.
I think I can confirm this issue. On a random basis I also have crashes after playing multiple videos. In general they happen when the playback of a video stops after already played some more videos before. Sometimes client crashes (Mediaportal has stopped working) sometimes I don't get any items displayed on the screen, sometimes the client don't react to anything and needs to be "killed" in task manager. As this seems to be random and only after using the client for a longer time, it most likely is hard to find, I fear...

did you check the event log after such a crash?

 

[Lehmden]

Don't remember but I will have a look next time this happens..

It's worth a try to update. The last time it fixed some crash issues already, but obviously not all.
