Re: [gst-devel] GstPolyBin idea and request for comments

[Stefan K. <en...@ho...>]

Hi Benjamin, Eduard and others,

I have reworked my thoughts under:
http://www.buzztard.org/index.php/Polyphonic_elemnts

Currently I tend to like idea 1 better. Elements that can be used as polyphonic 
elemnts just need to implement that. Now the question to bilboed is, if you see 
any problem is GstController also controlling something else.
I'll look over the API proposal to check where is applies.

Anymore comments are really welcome ;)
