[MPlayer-users] "librtsp: buffer overflow in rtsp_get" error when trying to play RTSP stream

[Lissanro Rayen]

I'm trying to play RTSP stream from IP camera. With mpv, vlc, ffplay or 
gst-launch-1.0 it plays fine. But with mplayer it just crashes with 
"librtsp: buffer overflow in rtsp_get" error. This happens both in 
mplayer 1.4 (compiled myself) and mplayer 1.3 (it comes with Ubuntu). 
Any suggestions what can I do to fix or debug this issue?

The reason why I'm interested in mplayer is that there is a chance that 
it may give lower latency than other players, like mentioned here 
https://github.com/mpv-player/mpv/issues/4213 - with RTSP my issue with 
mpv seems to be similar, no matter what options I try it introduces very 
noticeable lag even even with low resolution MJPEG substream. So I would 
like to try mplayer instead and I would really appreciate any help.

For now I'm trying to use mplayer without any options to reduce latency, 
just trying to get it working with RTSP. Terminal output (I tried 
playing H.264 or MJPEG substream but the output is the same, 
login/password are not needed to play the stream):
