Listening To Multiple Media Streams On The Emacspeak Audio Desktop

1 Executive Summary

The GitHub version of Emacspeak now supports launching and controlling
multiple media streams. This enables one to listen to the news while
playing a music stream, or relaxing nature sounds.

2 Sample Usage

Here are some examples of using this feature:

1. Launch your favorite news station — BBC World Service in my
   case — C-e ; RET.
2. Place the News on the left channel — C-e ; (.
3. Persist the currently playing News stream by invoking command
   emacspeak-m-player-persist-stream bound to C-e ; \. This lets
   you launch a second stream via Emacspeak media key C-e ; rather
   than controlling the currently playing stream.
4. Launch a classical music media-stream — C-e ; lu RET for a lullaby
   media stream.
5. Now Emacspeak M-Player commands will control the most recently
   launched stream; you can once again invoke command
   emacspeak-m-player-persist-stream if you wish.
6. The previously launched (and still playing) News stream is now in a
   buffer named *Persistent-...*. Command
   emacspeak-wizards-view-buffers-filtered-by-m-player-mode can be
   used to list buffers that hold a live m-player instance. It is
   bound to b in emacspeak-m-player-mode. I also bind this command
   to C-; ; in my global keymap.
7. You can make an M-Player instance current by switching to its
   buffer and invoking command emacspeak-m-player-restore-process
   bound to / in emacspeak-m-player-mode.
