Not able to create decoder element using gst-omx plugin in android
I am experimenting on how to use gst-omx plugin to access h/w decoder/encoder in Android. So I built one simple NDK C application , creating a playback pipeline using h264 omx decoder element. But when I try to execute I get the following instruction failed.
decoder = gst_element_factory_make(""omxh264dec", "h264");
g_printerr("decoder elements not created.... Exiting\n");
Please note that, prior to this,
A) I built gst-omx plugin for Android and then put this plugin into gstreamer 1.0 folder.There after using NDK to build gstreamer_android.so and my sample app.
B) Then I built a test app using NDK and gstreamer 1.0 to use omx plugin along with other plugin.
In my Android.mk, I mentioned
GSTREAMER_PLUGINS := coreelements videoconvert audioconvert audioresample playback omx
which builds fine without any complain. So I believe there is no problem with OMX plugin creation and packaging that into android_gstreamer.so
What am I doing wrong? is there any step that I am missing?
How to ensure, if the said element is loaded or not?
I checked gstomx.c :plugin_init, and I found the following line
ret |= gst_element_register (plugin, elements[i], rank, subtype);
But couldn't figure it out what would be actual h264decoder component name and why is it failing.
