@doskabouter Any ideas?

For that I need a bit more info... Steps to reproduce and especially: full set of logs where this happened

Upgrade install of 32-bit MP 1.38 over 32-bit MP 1.37 on 32-bit Windows 7

You have the correct version of the library.

[solved] - MP 1.38 crashes with video play after updating from 1.37 to 1.38

I just updated from 1.37 to 1.38. MediaPortal 1.38 exits abruptly when stopping video playback. I did three tests; Debug with Titan: Music has no errors, TVRecordings and live TV have no errors. MyVideo playback plays the movie fine, but when stopped, MP disappears. With plugins in...

Yep, that solved it for me too. But I think the problem is more widespread than 4 or five users. First I roled back to 1.37 and thought I simply skip 1.38.
I think more users will act like this. Maybe an installation advice on the download page will help others.

Maybe an installation advice on the download page will help others.

During installation, it checks whether VCRedist 2025-2022 is in the system, and if it is not, it is installed. The current version is checked by GUID, if it is registered, then everything is fine. If not, we update or install. But Microsoft seems to have updated the version of VCRedist 2025-2022 and did not update the GUID, so the installer does not understand whether this is a new version or an old one.

Hello everyone.

I updated MP from 1.37 to 1.38.1 today and experienced this issue. Interestingly, only playing files with the "video" codecs crashed MP, playing .ts files with TsReader worked fine.
I found this topic, updated the 2015-2022 VC redist to 14.44.35211 and now I can play videos one time after starting MP but if I stop and then try to play again, MP still crashes to desktop.

Please find logs attached. Started MP, played a .mp4 (played fine), pressed Stop, tried to play it again => crash to desktop.

Cheers.

EDIT: saw in the logs that it was complaining about MpcSubs.dll causing the crash, so I disabled subtitle support, and now it doesn't crash.
So it seems the problem is with that library. (maybe other people who don't have the crashes anymore are not using subtitles ?)

If it can help, I found a memory problem :

MpcSubs.dll causing the crash

Please find logs attached. Started MP, played a .mp4 (played fine), pressed Stop, tried to play it again => crash to desktop.

Yesterday I watched a movie, TV series, online video with my family, the movie had subtitles. No problems.
But I have x64 installation. Maybe it makes sense to try switching from x86 to x64?

I think it's related to Titan (too heavy for my 4 GB VRAM ?), because I don't see those messages with my normal setup that uses Default Wide HD (MP's debug tool forces switching to Titan to generate the logs)

I can't on my HTPC because I'm using ReClock which is 32-bit only.

Is it possible to install 32-bit and 64-bit MP concurrently on the same machine to test?
If not I'll see if I can reproduce the issue with my desktop computer and try 64-bit on that one.
