A customer complained on video playback problems which had symptoms of software compatibility issue. At certain operation modes software froze leaving the only option to kill process and restart.
I appeared that the system has a third party DLL installed, a new hero name’s – picapmk4.dll. The DLL registers itself as Video for Windows codec and is clearly indicating capabilities it does not really support.
The DLL itself has no indication of its source, no valid version info. Instead it has GPL v2 embedded, XviD logo and about box resource template showing up as “PMK4 Video Codec”.
Looks like crapware, which is hostile to DirectShow environment, with possibly GPL compliance issues.
