Summary0007067: Scanning files in Unskinned mode --> AV
DescriptionWhen scanning files that include videos in unskinned mode, when the scan completes, an AV occurs in ffdshow.ax. I suspect it's related to the automatic creation of Thumbnails.

The bug occurs in unskinned mode only.

The same problem happens to me, note that it doesn't seem to be related to the unskinned mode, it's happens anytime a thumbnail for MKV is being created. Seems to be a regression.

More testing has shown that the problem is in an installed old version of ffdshow. It's unclear why:
1. Did the crashing start, since ffdshow has been installed there for a year?
2. Is this installed ffdshow version used, when our codec pack is installed?
3. Why it doesn't crash when I disable our codec pack? Note that it doesn't generate the thumbnail either in this case, even though the video plays fine in MM.

It seems to be all caused by mixing locally installed dlls and those installed globally in system (in this case in ffdshow folder). We should improve loading, so that in case our codec pack is present, it's always fully used. After this fix, probably only item 3. above will remain.

Fixed in codec pack 1.06, please uninstall previous version and install new one and test.
The problem was in dll mixture - our ffdshow.ax is not comaptible with old libavcodec.dll, and the loaded dll was taken from some old ffshow installation, for some reason. I renamed our dlls to avoid these problems.

Problem in case 3 is tracked in issue 0007072.
