Looking for help: iOMX interface for gst-omx plugin

[Umashankar Chikkamath]

Hello Everyone,
From past more than 2 weeks I’m trying to resolve issue of
running simple gstreamer pipeline on Android 4.3. Here I’m using gst-omx plugin
to access hardware codec (omxh264enc) of Samsung S4 device(qualcomm
chipset).(Device has stock OS and unrooted)  I’ve set the right gstomx.conf
file as per Samsung S4 device 
Gstremer pipeline( Cerbero GST SDK  for android build is using to run gst app)
and  pipeline is  filesrc location=/mnt/sdcard/akiyo_qcif_nv12.yuv
! videoparse format=nv12 width=176 height=144 ! omxh264enc ! filesink
location=/mnt/sdcard/Test.264
Device details:  Samsung Galaxy S4 GT-I9506 Android version 4.3
 
and I can see the messages from adb logcat that
“gst_omx_core_acquire Successfully loaded core '/system/lib/libmm-omxcore.so'”
and “gst_omx_core_acquire Successfully initialized core '/system/lib/libmm-omxcore.so'”
. However I’m facing issue of accessing hardware and error is :
“gstomx.c:686:gst_omx_component_new:<omxh264enc-omxh264enc0> Failed to
get component handle 'OMX.qcom.video.encoder.avc' from core
'/system/lib/libmm-omxcore.so': 0x80001000”.
After debugging and going through documents” In order to
access the OMXIL functionality from a multimedia application, Android provides
IOMX interface and where the OMXIL components are owned by mediaserver
process”.
I haven’t find any such code with gst-omx plugin about iOMX
interface  i.e IMediaPlayerService in
mediaserver implements getOMX() function.
 
Is anyone tried to access hardware codec using gst-omx on
any android platform?. How should I approach to resolve this issue. I don’t
think so it’s easy to implement such that iOMX can communicate with gst-omx
plugin. 
Please advise/help.
Thanks,
-Umashankar
