Thumbnail Generation Fails on Select Movies

[dan-boehm]

For select movies in my library, the automatic thumbnail generation feature will fail. For these movies, it will take quite a long time, almost appearing as if it hung. This has occurred for 10 out of 222 movies.

Of those 10, 9 use the H.264 codec, but the other uses the AVC1 codec. There are other movies in my library that use these codecs that were able to generate thumbnails.

This problem occurs both during automatic scraping and when using the function manually within the Edit Movie Frame Extraction tab.
