Hi, Thanks for the info. That works for the ffmpeg plugin but wasn't implemented at all in the direct show function. I have posted a submission which adds a new function ( getCurrentTime ) to ImageStream and have implemented the new methon in the direct show plugin, and implemented it in ffmpeg by simply calling getReferenceTime.
I took this approach as I am not sure what the 'correct' meaning of getReferenceTime is as there is also a setReferenceTime as well as a seek function.

For the slider, I get the maximum value from the ImageStream->getLenght() method and to update the current position I call periodically ImageStream->getReferenceTime(). I think that this is the 'curentTime' function you are looking for. If you need any help, just let me know ;) Cheers, Julen. 2011/9/23 Christiansen, Brad <[email protected]<mailto:[email protected]>> Hi, I am creating a basic video player using the ImageStream class. I have created a standard 'position' slider to seek within the stream. Seeking is working with no problems but I cant see any way of reliabily updating the position of the slider as the stream is played. As well as the seek() and length() function I was hoping to find a 'curentTime' like function, basically the 'getter' for 'seek'. Without this function it looks like I will have to assume that length and seek are both in seconds and then calculate my own 'currentTime' based on elapsed time since play was called. This seems overly complex and somewhat unreliable as it also assumes that the stream is playing with exactly the correct timing. Has anyone solved this? Have I missed something?
