How to record flash video from rtp site? (The resulting flv file is unplayable)

[mzcl-mn]

Software used:

Replay Media Catcher (works)

rtmpdump / rtmpsrv v2.4 7340f6d~git on Ubuntu 11.10 x86_64 (doesn't produce a readable flv file)

Hello everybody. I have posted almost this same post on another forum here at stream-recorder so I am going to edit it so it won't be regarded as spamming and refer it back to this one. The previous location was:

http://stream-recorder.com/forum/rec...al-t11359.html

I think this forum here would be much more appropriate, but forgive me if I am wrong...

Here is the story:

I am trying to record a video program from 'rtp' video on demand site. As I am trying to migrate to linux I much rather prefer not to use windows. It is a little cumbersome to divide the pc's time with another OS when maybe all the tasks could be done with Linux.

Let us move on...

So, I begun trying rtmpdump to see if I had some success.

rtmpdump works well on live audio shows from the same rtp domain. (That is if I use the live option)

But... for videos (namely this 'planetamusica' program) it doesn't.

Version one of the command:

# rtmpdump -r "rtmp://h2a.rtp.pt/redirectvodrtp" -a "redirectvodrtp" -f "LNX 11,2,202,228" -W "http://www.rtp.pt/swfjs/player/player.swf" -p "http://www.rtp.pt/programas-rtp/index.php?p_id=28042&e_id&c_id=1&dif=tv" -y "nas2.share/videos/auto/planetamusica/planetamusica_1_20120331" -o planetamusica_1_20120331.flv

(This was version one of the command that was output from standard procedure with rtmpsrv).

But, unfortunately, even with it I would end up with a large file (an unreadable one, too).

So I discovered that the file in question is one that can only be downloaded with the live option set. So I added the -v option.

But when that live option is set, the redirection prevents it from being downloaded.

So, next phase, was to verbose the output. Doing this I got the redirection url. So, I replaced the original rtmp url by the one that is referred by the redirection, and erased the -a option and its value.

Also, after some reading of rtmpdump man's pages I realised that most of the other parameters might not be necessary after all, so I slimmed the command version to this one:

# rtmpdump -v -r "rtmp://62.41.78.105:1935/vodrtp"  -y  "nas2.share/videos/auto/planetamusica/planetamusica_1_20120331" -o planetamusica_1_20120331.flv

Still, the file that I got is not playable.

Can there be any solution to this issue?

Thanks in advance.

use mplayer2,vlc2

mplayer2 "rtmp://62.41.78.105/vodrtp/nas2.share/videos/auto/planetamusica/planetamusica_1_20120331" -dumpstream -dumpfile t.flv

vlc "rtmp://62.41.78.105/vodrtp/nas2.share/videos/auto/planetamusica/planetamusica_1_20120331" --demux=dump --demuxdump-file=t.flv

Dear chap,

Thanks a lot!

Worked like a charm!

Cheers!

it was a rarely occurring bug in rtmpdump. rtmpdump wasn't saving flv header into file making it unplayable. i have fixed it. check the following package. it also supports automatic redirection handling.

Hello,

Thank you very much for all your suggestions.

Been trying to compile following KSV instructions.

Still, I have been unsuccessful.

I keep getting the "undefined reference to `sqrt' `atan' and `exp'" functions, even if I use the -lm option inserted either on the XLDFLAGS declaration on the bash, either on LDFLAGS declaration on the makefile.

Can you help me?

Thanks.
