Hi, What you have done so far is good, except for one minor issue. You should not be touching the pvplayer.cfg file. Instead, you should be creating your own .cfg file that will be exported to the /system/etc/ folder.
You could add the line "$(call add-prebuilt-files, ETC, myomxmp3.cfg)" to your makefile that lists your LOCAL_PREBUILT_LIBS. /============================== $(call add-prebuilt-files, ETC, myomxmp3.cfg) LOCAL_PREBUILT_LIBS := MyLibrary.so include $(BUILD_MULTI_PREBUILT) LOCAL_SHARED_LIBRARIES := MyLibrary ==============================/ Now, for the OpenCORE framework to load your omx core before the PV omx core, the trick is to rename your .cfg file as 01_myomxmp3.cfg. While dynamic loading of omx cores we do a bubble sort of the .cfg files based on the name of the .cfg files. Our updated documentation based on OpenCORE 2.1 will explain this. -Ravi On Mar 1, 11:50 pm, Yogi <yogesh.agrawal2...@gmail.com> wrote: > Hi Ravi, > > We have followed the below step to integrate our MP3 OMX component. > > 1.Pushed ".so" to the "out" folder by the following way > > /============================== > LOCAL_PREBUILT_LIBS := MyLibrary.so > > include $(BUILD_MULTI_PREBUILT) > > LOCAL_SHARED_LIBRARIES := MyLibrary > ==============================/ > > 2. wrapper interface file defined in "omx_core_plugin" is modified to > include our ".so". > Created another "*My_sharedlibray.mk" to integrate wrapper > interface. > Wrapper interface file is placed under "omx_sharedlibrary/ > my_interface/src" and build. > > 3."*mp3_sharedlibrary.mk" has been modified to remove the lines for > compiling component and decoder sourcecode."omx_mp3" and "mp3" folders > are > removed. > > 4.In /system/etc/pvplayer.cfg of "out" folder, entry has been added as > defined in integration doc. > > 5.our omx shared library(.so) includes omx core also. > > As there are two omx core library i.e ours and PV's,its always > executing the PV's omx core library. > Its should execute our inteface & omx core if we try to play mp3 clip. > > I tried one experiment,apart from the above five steps: > 6.
