>From code, I find decodebin will not put decodesink into its element factory, decodebin only support elements with klass is "Demuxer", "Parser", "Decoder", "Depayloader". so playbin will select decoder, not decodesink. ________________________________ From: Liang Zhao [mailto:liangzhao.bit at gmail.com] Sent: Friday, February 27, 2009 2:37 PM To: Stefan Kost Cc: gstreamer-devel at lists.sourceforge.net; gstreamer-embedded at lists.sourceforge.net Subject: Re: can playbin handle the sink with decodingfunctions? Suppose decodesink has higher rank than decode, and playbin2 will choose decodesink, so how will playbin select ? select decodesink and fail?

Choose the best way to decode files for you platform and ship that set of needed plugins. If There are multiple decoders for the same format, autoplugging will pick whater has the highes rank and if even there are multiple, it takes what it find first.
