Thanks for the response Mortiz, Don't know how I missed that.
They were compiled with mingw64 so I'd say it's safe to assume opencv is 64 bit.

Do the libs you have downloaded with pacman correspond to the target you are compiling your ffmpeg for? (Yes, I do see there's a "64" everywhere in the paths - just wondering.) *Shrug* Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
