Maybe there needs to be a new kind of sound device (/dev/sound/play or something) which for typical sound hardware, does the decoding, and for A2DP can either decode or send the packets across, depending on whether it can negotiate a compatible decoder on the device. Having it work only with one library/toolkit like gstreamer is kindof limiting. And some day, I bet there will be A2DP support for even more codecs. FLAC would be awesome (but you'd need EDR I suppose).=20 So say if the device supports SBC, MP3 and FLAC, you could send MP3 directly, and encode everything else as FLAC. A player program would only need to open the /dev file and write MP3/Ogg/whatever packets to the device, after stripping off any metadata. The ALSA A2DP driver was supposed to be in userspace anyway, right? ------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
