[MPlayer-users] a problem when playing h.264 file

[binli1115]

Hi everyone: I use mplayer that compile the live source as  the client ,use live serve as the serve .when I use the mplayer to play the RTP format of h.264 file in the serve ,the message is as follows:(some English is translated by myself)
[root at localhost MPlayer-1.0rc1]# mplayer rtsp://202.194.**.**:8554/h

playing rtsp://202.194.20.87:8554/h。
STREAM_LIVE555, URL: rtsp://202.194.20.87:8554/h
Stream not seekable!
check the format of the file。
Initiated "video/H264" RTP subsession on port 32772
demux_rtp: Guessed the video frame rate as 30 frames-per-second.
       (If this is wrong, use the "-fps <frame-rate>" option instead.)
VIDEO: [H264] 0x0 0bpp 30.000 fps   0.0 kbps ( 0.0 kbyte/s)
Xv: could not grab port 65
Could not find free Xvideo port - maybe another process is already using it.
Close all video applications, and try again. If that does not help,
see 'mplayer -vo help' for other (non-xv) video out drivers.
==========================================================================
open the codec of video: [ffmpeg] FFmpeg's libavcodec codec family
chosen codec of video: [ffh264] vfm: ffmpeg (FFmpeg H.264)
