#!/usr/bin/perl -w
#  $Id$
# -----------------------------------------------------------------------------
#  Purpose:
#    - probe the camera
#    - pre-tune camera befor for retriever (RC and Audio)
# -----------------------------------------------------------------------------
#  Call:
#    probe DEVID=123   
#    probe DEVID=123 PROBE=FAST  
#    probe DEVID=123 DEVIP=192.168.17.177 [ ... ]
#    probe DEVIP=192.168.17.177 USRNAME=admin PASSWD=pass PROBE=DEFINE
# -----------------------------------------------------------------------------
#  Does:
#   0. can be called without DEVID argument. 
#      In this case DEVIP,USRNAME,PASSWD should be provided in command line
#   1. load $APL_CONF/<DEVID>/conf if DEVID is provided
#   2. combine conf and args into one hash
#   3. connect to camera over http and read MODELID and FIRMWARE
#   4. report MODELID|FIRMWARE|STATUS to $APL_CONF/<DEVID>/conf.probe and stdout
#   5. if PROBE=DEFINE then get
#         IMAGESIZE_LIST,MEDIA_FORMAT_LIST
#         AUDIO_LIST,AUDIO_FORMAT_LIST
#         SNAPSHOT (picture)
#   6. set RC camera attributes    if mpeg4 | h264
#   7. set AUDIO camera attributes if AUDIO is on 
#   8. example output:
#       AUDIO_SET=OK
#       FIRMWARE=5.02
#       MODELID=Q1755
#       RC_SET=OK
#       STATUS=OK

#       STATUS=OK
#       SNAPSHOT=/tmp/probe/192.168.17.177-12367576123.jpg
#       IMAGESIZE_LIST=640x480,480x360,320x240,240x180,176x144,160x120
#       MEDIA_FORMAT_LIST=mjpeg,h264
#       AUDIO_LIST=off,on
#       AUDIO_FORMAT_LIST=g711,g726,aac
#   9. sample errors:

#       STATUS=ERROR: PCE-0002 [101] USRNAME and PASSWD should provided

#       STATUS=ERROR: PCE-0030 [101] Cannot get MODELID
#       note: [101] is DEVID
#  10. warnings:
