[MPlayer-users] 1 second latency and complain about GStreamer when accessing to RTSP stream from AXIS camera

[Faisal Mozher]

Hi,
I'm using ubuntu 14.04. I'm trying to play the audio from an `rtsp` audio
stream provided by Axis P5515 camera but I have about a second latency. I'm
using the following command:

mplayer rtsp://username:***@10.10.210.2/axis-media/media.amp
-rtsp-stream-over-tcp -novideo -nolirc -prefer-ipv4 -benchmark -nocache

I get the following reply in the terminal:
MPlayer SVN-r37881 (C) 2000-2012 MPlayer Team

Playing rtsp://username:***@10.10.210.2/axis-media/media.amp.

How to get rid of this complain?

librtsp: server responds: 'RTSP/1.0 401 Unauthorized'
rtsp_session: unsupported RTSP server. Server type is 'GStreamer RTSP

Is this the reason why it has about one second latency? Could you please
suggest me any idea regarding reducing the latency?

That year is weird. Maybe should do a "make clean"?

It's using MPlayer's really old, weird and unmaintained librtsp.
You could try
ffmpeg://rtsp://username:***@10.10.210.2/axis-media/media.amp
instead, maybe it works better.
