Help with better syntax for audio stream dump


 
Hi!

I need to capture an audio live stream for 2 hours with RTMPDump v2.4 GIT-2011-07-11 (Compiled by KSV) . After a lot of searches , trial & errrors I have the following syntax:
Code:
rtmpdump -r "rtmp://cp126784.live.edgefcs.net/live/" --live -v -y "enlevko@73167"  --swfVfy "http://enlefko.fm/sites/all/themes/enleyko/flash/EnLefko_RTMPPlayer.swf"    --stop 7200  -o tzoum.mp4a
The problem is that the stream dump is not consistent. Sometimes it just stays at

ERROR: RTMP_ReadPacket, failed to read RTMP packet body. len: 4
Other times I get the notorious
Quote:
Received FLV packet before play()!
But many times it works ok. Is there something wrong with my syntax?

Re: Help with better syntax for audio stream dump


 
My bad , I thought the url was pretty obvious from the --swfVfy parameter.
Site: http://enlefko.fm/
Player is Jplayer port of Drupal
swf object info taken by page source : swfobject.embedSWF("/sites/all/themes/enleyko/flash/EnLefko_RTMPPlayer.swf?1"

rtmexlporer attempt to parse data from rtmpsrv :
Code:
rtmdump -r "rtmp://cp126784.live.edgefcs.net/live/enlevko@73167" -a "live/enlevko@73167" -f "WIN 11,5,502,135" -W "http://enlefko.fm/sites/all/themes/enleyko/flash/EnLefko_RTMPPlayer.swf?1" -p "http://enlefko.fm/" -y "enlevko@73167" -o enlevko@73167.flv
RTMPDump v2.3
Connecting ...
INFO:Connected
ERROR: Closing connection: Netstream.Play.StreamNotFound
So rtmpexlorer doesn't correctly identify the stream file due to "enlevko@73167". So I had to find a correct syntax, thus the syntax on my first post:
Code:
C:\rtmpdump-2.4>rtmpdump -r "rtmp://cp126784.live.edgefcs.net/live/"  --swfVfy "
http://enlefko.fm//sites/all/themes/enleyko/flash/EnLefko_RTMPPlayer.swf"  --liv
e -v -y "enlevko@73167"  --stop 7200  -o tzoum.mp4

But dump is not consistent and because I need to schedule this command, I want it to be failproof. Any help is greatly appreciated.

If you have Bash, I have a workaround for the "Received FLV packet before play()!"

I have a VPS with CentOS and I just build it from source, rtmpdump runs fine so I can make use of a bash script!

You can use this script to stop RtmpDump after certain period of time, without using "--stop"

github.com/svnpenn/a/blob/master/rtmp-stop.sh

Code:
rtmp-stop.sh 10 rtmpdump -r "rtmp://cp126784.live.edgefcs.net/live/en
levko@73167/enlevko@73167" -o "enlevko@73167.flv" -v
