But I finally noticed the difference: I was using one of the .pls playlist link given in emms-stream-default-list. And playlist parsing is disabled in mplayer by default. You have to allow it with for instance: --8<---------------cut here---------------start------------->8--- mplayer -ao null -vo null -endpos 0 -nocache -playlist http://somafm.com/bagel64.pls --8<---------------cut here---------------end--------------->8--- Also, in this case of a stream being played, mplayer returns the name of the stream and not the name of song currently playing, because there isn't any "ICY Info: StreamTitle" in the output with these options. You can however get this field if you enable a minimum cache (150Ko is not enough) with for instance: --8<---------------cut here---------------start------------->8--- mplayer -ao null -vo null -endpos 0 -cache 180 -playlist http://somafm.com/bagel64.pls --8<---------------cut here---------------end--------------->8--- It's fine when you run mplayer in a terminal but the temp buffer used by emms-stream-info-mplayer-backend gets filled by several Mo of "Cache fill: 0.00% (0 bytes)" messages. You can get rid of these messages, and some other, with the following cmdline options: --8<---------------cut here---------------start------------->8--- -msglevel decaudio=-1:cache=-1:statusline=-1:cplayer=-1 --8<---------------cut here---------------end--------------->8--- The clean thing would be to remove all messages (with all=-1) and then only enable the right modules but I couldn't find the module responsible for the ICY info message. We can add these options to emms-stream-info-mplayer-backend but maybe the -playlist one should only be used when the url is indeed a playlist. > I also note that while setting `*emms-stream-info-backend*' is mentioned > in emms-stream-info.el, it isn't mentioned in the manual.
