infinite.loop · November 16, 2009

Some time during the last few days, a bug has been introduced in StreamedMP's svn.

Currently in ListView, Thumbs generated by MediaPortal (MTN.exe) are nolonger displayed, and inside the error.log i find this.

Code:

For some reason this does not happen for all videovidels MP generated a thumbnail for. Some are still working.
But the issue itselfe is not random. After a restart of MP, it are always the same videos which no thumbs are displayed for.

If i revert to rev688 (2009-11-10) then the error messages and the issue is gone.

I hope this helps. If you need more testing, please tell me.
