DVB, Playbin, and video issues

[Russel Winder]

Hi,

In Me TV I have been using a Playbin and letting it construct the pipeline
needed to deal with DVB data streams. This seems to have worked well for me in
the UK. However some Australian users are complaining about interlacing issues
on the video. One person has proposed manually inserting a Deinterlacing
Element into the pipeline which solves their problem, but seems like the wrong
solution to me – but I may be wrong and them right.

It all really hinges on whether the dvbsrc plugin idea of interleaving is the
video idea of interlacing, and whether dvbsrc correctly identifies the correct
interleaving/progressive state of the video of the channel being displayed.

I think what I need to do to investigate all this is to be able to know what
the pipeline is that the Playbin creates for a given DVB channel, and then to
find out whether it is 576i, 576p, 1080i, or 1080p – the last of these is
highly unlikely, at least in the UK, just now for various political not
technical reasons.

Is there an easy way of getting the Playbin to display the current pipeline
and thence get at all the parameters being used?
