Original commit message from CVS: * gst-libs/gst/interfaces/mixeroptions.h: * gst-libs/gst/interfaces/mixertrack.h: Change the way these deprecated function pointers are removed so that the compiled ABI is unconditionally smaller. This sets in stone an ABI break that actually occurred when the things were deprecated in 0.10.14, which seems to be the best fix as the only known users are oss-mixer and sunaudio-mixer in gst-plugins-good.

* Naming:
|
|
*
|
|
* A track is a single input/output stream (e.g. line-in,
|
|
* microphone, etc.). Channels are then single streams
|
|
* within a track. A mono stream has one channel, a stereo
|
|
* stream has two, etc.
|
|
*
|
|
* Input tracks can have 'recording' enabled, which means
|
|
* that any input will be hearable into the speakers that
|
|
* are attached to the output. Mute is obvious. A track
|
|
* flagged as master is the master volume track on this
|
|
* mixer, which means that setting this track will change
|
|
* the hearable volume on any output.
