h.264 encoder issue

Sure, here it is. Thanks for your cooperation

This works

I am compiling this code with this

arm-none-linux-gnueabi-gcc -o gstream gstream.c -lz `pkg-config --cflags
--libs gstreamer-0.10`


I tried this too..

arm-none-linux-gnueabi-gcc -o gstream gstream.c -lz  -L $(LIB)/ `pkg-config
--cflags --libs gstreamer-0.10`

  [where LIB is the path where the libgstticodec.so library is for the
TIVidEnc is]
