[MPlayer-users] Mplayer in RTSP crash when network no longer reachable

[lonkaji]

hello,
I use mplayer for a small application that displays video from cameras
ip using RTSP.
I developed a GUI in pygtk using the slave mode of mplayer.
I encounter problems when the camera is no longer reachable for a random reason.
I try to hack mplayer with my knowledge of C but I feel that there are
at least 2 implementations in mplayer rtsp and I do not know where to
start.
for now mplayer crash with this log:

mplayer rtsp://root:pass@192.168.0.149/axis-media/media.amp -nocache

FramedSource[0x96baa88]::getNextFrame(): attempting to read more than

MPlayer interrupted by signal 6 in module: decode_audio
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.

I think this message "FramedSource[0x96baa88]::getNextFrame():
attempting to read more than once at the same time!" comes from
live555 rtsp librairy.
I would at least know how I can restart mplayer when it has crashed,
or better know hack mplayer to relaunching itself in a loop trying to
retrieve the video stream.
Thanks in advance for any help.
