rtmpsuck segmentation fault

bluebonic · #1 11-17-2014, 05:04 AM

Hi,

I'm trying to use rtmpsuck on debian wheezy. It basically works, but after a while I get a segmentation fault. I'm using a KSV patched version of rtmpdump. I'm not quite sure how to debug the crash, but I'm willing to try if someone can give me tips.

So far, I tried to get a dump with gdb. I manage to capture 3 crashes:

Code:

I also see messages like this quite often:

Code:

WARNING: ignoring too small audio packet: size: 0

Code:

ERROR: WriteN, RTMP send error 9 (46 bytes)

Any ideas?
