[MPlayer-dev-eng] rtsp stream not seekable

[qwen dux]

Hi,
I'm using latest cvs version of mplayer with live555 to play mpeg4
streams. but mplayer says:
$ ./mplayer rtsp://192.168.20.60/test.mp4 -cache 8192
...

but with mp4player I could seek the streams.
Is there a way to seek with mplayer? Any ideas? or how to set Darwin
Stream server, or make seekable stream source?

Thanks.
