Description Christian Fredrik Kalager Schaller 2013-09-02 19:22:37 UTC 
I am getting the following ugly, but non-critical messages when trying to encode an ogg vorbis file into ogg flac.

Comment 1 Tim-Philipp Müller 2013-09-02 20:52:00 UTC 
Thanks for pasting them all, but I think the first couple of hundred would have been sufficient :)

Could you attach an image of the pipeline please? (SVG preferably)

And is this with git master or at least 1.1.4?
Comment 2 Sebastian Dröge (slomo) 2013-09-03 07:40:42 UTC 
This was probably fixed by this already:

commit de7e1cb6dd8e5031b1d1d9a64fdda955bae54501
Author: Sebastian Dröge <slomo@circular-chaos.org>
Date:   Fri Aug 16 13:26:28 2013 +0200

    flacenc: Properly set headers via the base class instead of just pushing them downstream
    
    Prevents buffers from being send before the caps and segment events.



(backported to the 1.0 branch too for 1.0.11)
Comment 3 Christian Fredrik Kalager Schaller 2013-09-03 09:36:34 UTC 
Ok, tested with updated git checkout and the error is now gone as Sebastian predicted, closing as fixed.
