I'd probably have a look at gstreamer and see if there's a "visualisation" plug-in that would do what you want. https://gstreamer.freedesktop.org/documentation/audiovisualizers/index.html Something like: > gst-launch-1.0 filesrc location="${HOME}/music/by-track-artist/Santana/Let It Shine.ogg" ! oggdemux ! vorbisdec ! tee name=t ! queue ! audioconvert ! mux. t. ! queue ! audioconvert ! spectrascope ! videoconvert ! avenc_mjpeg ! mux. avimux name=mux ! filesink location=/tmp/test.avi might do what you want. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
