Should be there

http://packages.ubuntu.com/natty/libavcodec-dev

sudo apt-get install libavcodec-dev

 

On the lines just below the lines you posted should say this.

dyna.cxx(141)              DYNA Successfully loaded 'libavcodec.so'

dyna.cxx(411)  H264   DYNA Successfully loaded libavcodec library and
verified functions

By enabling this before calling simple.

export PTLIB_TRACE_CODECS=4

 

You should see this.

If you make install on the h323plus/plugins directory it should be detected.

 

Just make sure it is in one of the above directories.

Hi Simon,

Thanks for your reply.

I set environmental variable "PTLIB_TRACE_CODECS=4" and copied
"h264_video_pwplugin_helper"  in "samples/simple/obj_linux_x86" dir but
still getting same error: 

ERROR: H.264 plugin couldn't find GPL process executable:
h264_video_pwplugin_helper

and also  I am not able to see the directories the plugin searches for the
X264 helper.



Regards,
Ashwani

When running simple you will be able see the directories the plugin searches
for the X264 helper. 

The helper should be compiled with the x264 plugin.
