avutil-56.dll

Hello dear PCSX2-Team,

i have a question regarding a certain message in the System Console:

(DynamicLibrary) Loading avutil-56.dll failed: 126

This message appears once when i start the emulator and click on the Settings button (does not happen a second time - it happens only once after closing and opening the emulator) and always once each time the game settings of any game are opened. Is this problem with my computer or with the emulator? I always use the latest build. Thank you in advance!
