RE: When seek rate is set in reverse the current position isn’t updated.

[Nick.Adamson at gdlsuk.com]

Hi Sebastian.
I'm using Gstreamer 1.6.1 on windows 7.
In terms of knowing which elements are being used, when you use uridecodebin and playsink how can you tell?

I'm still quite new to gstreamer and am muddling my way through some of this.

Thanks.
Nick.

Which GStreamer version and which sinks are used for audio and video?
Also is this from a local file?

The code looks correct, at least nothing obviously wrong. You should check the debug logs to see where the position query exactly goes and why it is answered with a wrong value. In theory the audio/video sink should answer the query, and should return the value you're expecting.
So I would expect a bug in one of those two.
