I've just downloaded the newest ones. And got the same result. http://pastebin.com/ry1hdqsy

Re: Customized rtmpdump binaries with patch file


 
Great, that's just what needed!
Did you use the same binaries that have been uploaded to mediafire? (http://www.mediafire.com/file/5eep3w...mpdump-2.4.zip)
I used them with rtmpdumphelper. Maybe that's the cause of the problem?

yeah those are the latest binaries.

Code:

no, it has nothing to do with RTMPDump Helper. make sure new binaries are in the same folder as RTMPDump Helper.

Re: Customized rtmpdump binaries with patch file


 
I've just downloaded both zips (rtmpdump-2.4.zip from mediafire, from first post and RTMPDumpHelper from Nir Sofer's site). Extracted them in new folder (both in one). BTW, rtmpsuck's MD5 equals to yours.
Then I start rtmpdumphelper from that folder (it starts the rtmpsuck) and open the same test page (http://live.samaa.tv/). RTMPSuck starts capturing the stream, but saves it as samaalive.flv, without timestamp :(
I cannot understand it.
Everybody, please, test that issue too. It can't be that i'm the only lucky who experiences the overwriting problem.

@KSV

Hi KSV, first thank you for your work.

I was testing your patches and I think I found a bug:

Steps to reproduce:

- Try to dump one of the streams of Icasthd. Take into account that Icasthd works per sessions so you will need to get a valid one.

icasthd.tv/?p=channeldetails&id=skysports1

For Example:

http://pastebin.com/qEi703wk

When dumping this kind of streams, from time to time I get a segfault.

One of the times I was running with gdb and I got a backtrace:

Code:
DEBUG: Parsed protocol: 0
DEBUG: Parsed host    : edge.icasthd.com
DEBUG: Parsed app    : live?f=skysports1&t=1366736989&/

#11 0x0000000000402ab5 in ?? ()

Also happened with a compiled version in android with ffmpeg based player, backtrace in android shows:

Code:
#00  pc 00018630  /system/lib/libc.so (memcpy+48)
#01  pc 00035d7b  /data/app-lib/com.android-1/librtmp.so (AMF_EncodeString+70)

#08  pc 002c514c  /data/app-lib/com.android-1/libffmpeg-neon.so
The same crash in x86_64:

http://pastebin.com/EKxJvh23

It seems it's some problem handling redirects as sometimes ffmpeg outputs:

Code:
04-23 18:55:33.949: A/ffmpeg(7739): Problem accessing the DNS. (addr: @4.102.63.22)

What do you think?

It doesn't crash every time. For me it crashes from time to time. Maybe once every 5 intents. Also don't use rtmp://edge.icasthd.com:1935/live instead force a redirect response rtmp://edge.icasthd.com:1935/redirect3

Example:

Re: Customized rtmpdump binaries with patch file


 
Checking if null pointer seems to solve the crash.


Code:
void
AMF_Reset(AMFObject *obj)
{
  int n;
  for (n = 0; n < obj->o_num; n++)
    {
      AMFProp_Reset(&obj->o_props[n]);
    }
+  //check if null pointer
+  if(obj->o_props)
    free(obj->o_props);
  obj->o_props = NULL;
  obj->o_num = 0;
}

EDITED:

Doesn't Solve it. The culprit seems to be somewhere else

Re: Customized rtmpdump binaries with patch file


 
I made some MacOS executables and librtmp test files using the x86 darwin compiler on Ubuntu 10.04 (older OS due to older code :))

I need ATV1 and MacOS users to try:
