Nicolas/Tim,

If I make the buffer writable by adding below code just before
gst_video_decoder_finish_frame() call

   if(!gst_buffer_is_writable(out_frame->output_buffer))
   {
         gst_buffer_make_writable(out_frame->output_buffer);
   }


Then I am getting following error



(gst-launch-1.0:10963): GStreamer-CRITICAL **: gst_mini_object_unref: assertion
'mini_object->refcount > 0' failed

** (gst-launch-1.0:10963): CRITICAL **: gst_video_frame_map_id: assertion
