how to get the actual frame in ofVideoPlayer

I’m developing an app that syncs videos to an incoming timecode, so I’m having to seek to certain frames a lot. I’m finding that getPosition or getFrame will return the position I’ve last seeked to, regardless if the video player made it to that frame yet. I’ve filed an issue at https://github.com/openframeworks/openFrameworks/issues/1928 but I’d like to know if there is a way to get the last frame that was actually decoded.
