hi list,
I want to playback a Theora video file and output the audio to my bluetooth headphone. First, I try below command to playback an audio and output to bluetooth headphone, it works. $ gst-launch-0.10 -v filesrc location=ubuntu\ Sax.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! alsasink device=bluetooth Then, I playback the Theora video file and output audio to default (wired) earphone, it works. $ gst-launch-0.10 filesrc location=/home/ume/media/video/Experience\ ubuntu.ogg ! oggdemux name=d d. ! queue ! theoradec ! ffmpegcolorspace ! ximagesink d. ! queue ! vorbisdec ! audioconvert ! audioresample ! alsasink device=default Setting pipeline to PAUSED ...

bluez-utils package (in www.bluez.org) has a2dpsink element that handles sending audio to a bluetooth headset using a2dp, might be worth trying it.
It is capable of sending sbc audio (bluez-utils has a sbc encoder) and mp3.
