Need to set a clock in gstreamer pipeline that are comaprable to PTS values.

[Tim Müller]

Hi,

not sure what you're after exactly. You just want the pts values of the buffers rather than the position?

The position query will always return a value 
between 0 and the duration.

You can use the last-sample property (last-buffer in 0.10) to retrieve the last buffer and get the pts from that, but that rarely makes sense and might not be a monotonically increasing value or match the values in the bitstream.

Cheers
