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 <o:p class="" style=""></o:p></div><div class="" style="">Gstremer pipeline( Cerbero GST SDK for android build is using to run gst app)

“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

access the OMXIL functionality from a multimedia application, Android provides
IOMX interface and where the OMXIL components are owned by mediaserver
process”.<o:p class="" style=""></o:p></div><div class="" style="">I haven’t find any such code with gst-omx plugin about iOMX
interface i.e IMediaPlayerService in
mediaserver implements getOMX() function.<o:p class="" style=""></o:p></div><div class="" style=""><o:p class="" style=""> </o:p></div><div class="" style="">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. <o:p class="" style=""></o:p></div><div class="" style="">Please advise/help.<o:p class="" style=""></o:p></div><div class="" style="">Thanks,<o:p class="" style=""></o:p></div><div class="" style="">-Umashankar<o:p class="" style=""></o:p></div><div class="" style=""><o:p class="" style=""> </o:p></div><div class="" style="">More adb logcat details: <o:p class="" style=""></o:p></div><div class="" style=""><o:p class="" style=""> </o:p></div><div class="" style="">E/OMX-VENC-720p(24052):
