It was working all right. It's made with 2 parts: a patch to mplayer that exports the sound (the export audio filter in mplayer, see "man mplayer"; and the second part is the app to display the data (MPAV = MPlayer Audio Visualization) The main problem that time was that my patch to mplayer was not integrated, but it was a long time ago and it's in pre3. The other problem is that my app was only a proof-of-concept, it works but it's not that optimized (anyone with wider thread programming experience?) and it's not made from plugins, just uses GOOM, but it's easy to make plugin-able. Another problem is that GOOM requires some parameters to be defined in the Makefile (anyone that knows automake/autoconf to help here?) The app can be controled using stdin using --slave mode, it can even display text using some commands. It uses SDL. As it's split in 2 and the filter doesn't aggregate any [noticeable] load to mplayer, you can always have mplayer to export it's buffers and turn the MPAV when user press a choosen key, then kill the program when the user pressed that key again. (The only problem here is to devices like DXr3 and FB, which you need to release SDL from freevo, like we do with MPlayer/Xine). Ah, it takes a lot of CPU (goom's fault), probably we need to use some double pixel cheat, like WMP does. Here's a screenshot: http://gsbarbieri.sytes.net/mpav.jpg And here's the code: http://gsbarbieri.sytes.net/mpav-0.0.1.tar.bz2 I hope it still compiles!
