FreeSWITCH libpng on CentOS 7

[pbruining]

I'm using the release version of the RPM repository of FreeSWITCH on CentOS 7.
When we configure the use of video avatars the message:
"[ERR] switch_core_video.c:3046 This function is not available, libpng not installed"
pops in the logs. After searching people suggested the upgrade of libpng from 1.5 to 1.6. This is difficult to do in CentOS 7. I did it by installing the required so files in a separate directory and i modified the LD_LIBRARY_PATH environment variable. This did not help. I also looked at the code of FreeSWITCH. It looks like FreeSWITCH is not compiled with libpng support in it.

Could you create release RPM's with the support of libpng in it for CentOS 7?

I've tried rebuilding is with libpng and libpng-devel installed on CentOS 7. That did the trick. So just installing that RPM and rebuilding the release will have that fixed.

However rebuilding it with stock erlang from EPEL won't work. See #121 for that issue.

Thanks! That version is now running :)
