DESCRIPTION

17       udpxrec is a utility designed to record (save into a disk file) a  seg‐

OPTIONS

23       udpxrec accepts the following options:
24
25
26       -c <src_addr>:<port>
27               Channel i.e. multicast address and port from  which  to  record
28               data.
29
30       -s <ssm_source_addr>
31               Optional SSM source address.
32
33       -v      Enable verbose output [default = disabled].
34
35       -m <mcast_ifc_addr>
36               IPv4   address/interface   of  (multicast)  source  [default  =
37               0.0.0.0].
38
39       -l <logfile>
40               Log output to file [default = stderr].
41
42       -n <nice_incr>
43               Nice value increment [default = 0].
44
45       -B <sizeK>
46               Buffer size (65536, 32Kb, 1Mb)  for  inbound  (multicast)  data
47               [default = 2048 bytes].
48
49       -R <msgs>
50               Maximum number of messages to buffer (-1 = all) [default = 1].
51
52       -b <begin_time>
53               Begin  recording  at  [+]dd:hh24:mi.ss,  '+' signifies relative
54               timing (in N hours/min/sec).
55
56       -e <endtime>
57               Stop recording at [+]dd:hh24:mi.ss, '+' signifies relative tim‐
58               ing (in N hours/min/sec).
59
60       -M <maxfilesize>

62
63       -p <pidfile>
64               Pidfile for this process [MUST be specified if daemon].
65
66       -u <seconds_to_wait>
67               Seconds  to  wait  before  updating  on how long till recording

EXAMPLES

72       udpxrec -b 15:45.00 -e +2:00.00 -M 1.5Gb -n 2 -B 64K -s  87.141.215.251
73       -c 224.0.11.31:5050 /opt/video/tv5.mpg

75       Begin  recording multicast channel 224.0.11.31:5050 from source address
76       87.141.215.251 at 15:45 today, finish recording in two hours or if des‐
77       tination file size >= 1.5 Gb; set socket buffer to 64Kb; increment nice
78       value by 2; write captured video to /opt/video/tv5.mpg.
