LAV Splitter crash #303

Closed GoogleCodeExporter closed 9 years ago

Describe the issue you're having:
I created application which grab frames from video files using DirectShow. The 
application have 8 threads. Each thread read the same video file and grab 
frames simultaneously. The application crash when more than one thread try to 
read video which use LAV Splitter Source (mp4 or mov). Video files which not 
use LAV Splitter Source don't case such problems.

Sample mp4 file:

Yes, new version don't case such problems. But is it possible to detect 
programically which version of filter is installed? I'm asking because I want 
prevent crash of application if older version is installed on PC.

The .ax files all have version information attached to them, which you could 
check when starting up.
There is no API yet to query the version.
