Hi, I have successfully created lib for gstreamer and supported plugin by using NDK, now i want to test the working of so file, for that I create a application and create a exe by using NDK . Next step is to run the exe on android-emulator, for that first I load the exe into directory /data/temp by using adb push command, then push all the shared library which is required to execute the exe i.e. <a href="http://libglib-2.0.so/" target="_blank">libglib-2.0.so</a> <a href="http://libgmodule-2.0.so/" target="_blank">libgmodule-2.0.so</a> <a href="http://libgobject-2.0.so/" target="_blank">libgobject-2.0.so</a> <a href="http://libgthread-2.0.so/" target="_blank">libgthread-2.0.so</a> libgstcoreelements-gstplugin.so <a href="http://libgstreamer-0.10-libs.so/" target="_blank">libgstreamer-0.10-libs.so</a> libgstcoreindexers-gstplugin.so libgstreamer.so <a href="http://libgst-plugins-base-libs-0.10.so/" target="_blank">libgst-plugins-base-libs-0.10.so</a> libgstapp.so So everything is now in the same folder. Next step is to link the library at run time so for that I set the path by using LD_LIBRARY_PATH So up to now everything seem to be OK. Final Step: To execute the exe. Error: The strange thing that i observe that exe is able to execute some of the basic api of gstreamer like as, gst_init (&argc, &argv); bin = gst_pipeline_new ("pipeline"); But while executing following command, exe not able to create appsrc element. appsrc = gst_element_factory_make ("appsrc", NULL); --------> Not able to create this element I have crossed check and I found I have all the .so file that is required to execute the code. GLib: Cannot convert message: Could not open converter from 'UTF-8' to 'ASCII' ----> I am getting this message also while executing the code. So, If any body face such type of error or want to share something on this issue then please share your valueable point. Thanks
