opelcalibra · #1 09-16-2012, 06:14 AM

Hi All,
I used to have this stream working, then something changed and i can no longer get the correct url. i tried 2.4 and the ksv build with no success. the webpage is

http://kanalia.eu/player.php?id=91

and im trying

rtmpdump -r rtmp://freeview.fms.visionip.tv/live/tvnetwork-hellenictv-sigma-hsslive-25f-4x3-SDh --live

all i get is failed to read rtmp packet header. thanks in advance for your help!

Though the trick posted by karlo (adding mp4: to playpath) works for the time being but it wasn't the actual reason of breakage. if you monitor it with wireshark you will see that it's still using the old playpath (without mp4:) but it has added two non-ASCII characters at the end (CRLF = \x0D\x0A = \r\n) which are newline characters. AFAIK it's not possible to pass on those characters as command line arguments because windows cmd shell treats everything separated by newline as separate command.

Like this

Code:

$ rtmpdump -r rtmp://freeview.fms.visionip.tv/live/tvnetwork-hellenictv-sigma-h
sslive-25f-4x3-SDh$'\r' -o out.flv

Ideally what needs to happen is allow RtmpDump to interpret escape sequences, like "echo" does

Code:

$ help echo
echo: echo [-neE] [arg ...]
    Write arguments to the standard output.

    Display the ARGs on the standard output followed by a newline.

    Options:
      -n        do not append a newline
      -e        enable interpretation of the following backslash escapes
      -E        explicitly suppress interpretation of backslash escapes

    `echo' interprets the following backslash-escaped characters:
      \a        alert (bell)
      \b        backspace
      \c        suppress further output
      \e        escape character
      \f        form feed
      \n        new line
      \r        carriage return
      \t        horizontal tab
      \v        vertical tab
      \\        backslash
      \0nnn     the character whose ASCII code is NNN (octal).  NNN can be
        0 to 3 octal digits
      \xHH      the eight-bit character whose value is HH (hexadecimal).  HH
        can be one or two hex digits

This way you could add switch, maybe "-E", and that enable interpret carriage return, for example.

As always you guys are awesome. Thankyou very much for your help this time and every other time I have required it.

My in-laws will be extremely appreciative!

svnpenn · #8 10-19-2012, 11:55 PM

You can actually do this without Bash, you just encode the Carriage Return as %d

lists.mplayerhq.hu/pipermail/rtmpdump/2012-October/002109.html

Code:

$ rtmpdump -o a.flv -r rtmp://freeview.fms.visionip.tv/live/tvnetwork-hellenict
v-sigma-hsslive-25f-4x3-SDh%d

Please note that the only reason "%d" works (as opposed to "%0d") is because it's at the end of the string.

If you were to do somehting like "foo%Dabc", "%Da" would be replaced with 0xda and you'd lose your "a".
If you were to do something like "foo%Dzabc", "%Dz" would be replaced with 0x0d and you'd lose your "z".
