[x264-devel] can not encode h264 but can decode

[Raju Nanduri]

Hi

I am running into a problem where it can decode h264 using  my opal based application using x264 plugin but it can not encode. Not sure what to look for specifically in  
logs as most of h264 related entries in log look just fine.  Here are 
some selective log entries in the order of call flow. Any help is greatly appreciated.

Hi
The simpleopal  exe can decode  h264 it receives from a H323 end point but 
can not encode h264 resulting in 1-way video on Ubuntu 10.04(lucid).  
Here are relevant log entries generated by simpleopal. ( I also tried as sudo but still got the same result).  Any idea what could be missing  
here?
