Hi, I play audio stream (mp3) using RTSP and I want to adjust dynamically the plackback speed (using the playback speed variable). However, I can play faster only for a short time (until buffer underflow or overflow). So, I want to adjust audio buffer size to increase this time. But using "-cache 1024" (which is a lot of audio buffering!) and "-min-cache 50" seems to have no effect. Are these options works only for video playback ? How does Mplayer manage audio buffering (default size) ? Thanks in advance, Pierre Crc
