<html><head></head><body>Hi, Are you sure the nleurisource is properly configured? You can try to emit the `commit` signal but by default when going to PAUSED we commit the timeline automatically iirc. Can you try to dot the pipeline also (on error)?

I am trying to do some nonlinear stuff and trying to use NLE elements from GES. I have nlecomposition, which contains nlesource, which in turn contains nleurisource. However, every time try to put pipeline into playing state, I get this: ERROR nlecomposition nlecomposition.c:1812:_seek_current_stack:<composition> Can't seek because no pad available - no children in the composition ready to be used, the duration is 0, or not committed yet </blockquote> Just a guess, maybe "or not committed yet" is what's missing? Tom <blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">I tried to use audio test source added to nlesource, and I got same issue as well. When I have just nlesource added to composition, it doesn't trigger error, but obviously it doesn't have anything to play. Poking at logs *:5 it looks like nlesource has issues connecting pads with child - it tried to connect to sink for audio test source, which did not make sense. Any suggestions and hints would be appreciated :) Peter. </blockquote></pre></blockquote></div></body></html>
