[android-porting] UUID association problem

[HV]

Hi,

I've written my own MPEG-4 decoder component and having issues when
the associated .cfg file is being read. I get the following error:

E/PV ( 828):
PVLOG:TID(0xca690):Time=42:OsclLibraryList::Populate '/system/etc/
mymp4.cfg' IN
E/PV ( 828):
PVLOG:TID(0xca690):Time=44:OsclLibraryList::Populate - Found a (,
reading uuid
E/PV ( 828):
PVLOG:TID(0xca690):Time=45:OsclLibraryList::Populate - uuid not a
match, skipping line
E/PV ( 828):
PVLOG:TID(0xca690):Time=46:OsclLibraryList::Populate, Didn't find any
DLL for the OsclUuid

As for the UUID, I just got a new one from the web. The mymp4.cfg file
looks like this:

(0x8b98b3b0,0x51c2,0x11df,0x98,0x79,0x08,0x00,0x20,0x0c,0x9a,
0x66),"libomx_mymp4dec_sharedlibrary.so"

& I have an entry in pv_omxcore.h as:

#define PV_OMX_MYMP4DEC_UUID OsclUuid(0x8b98b3b0,0x51c2,0x11df,
0x98,0x79,0x08,0x00,0x20,0x0c,0x9a,0x66)

All this is similar to the software decoder, but I'm not sure what
else I've missed. Any clues? Is there any other association that I
need to establish between the decoder dll & the UUID?

Thanks
HV

Hi,
is this resolved?

we never used to change the OSCL UUID from what's specified in OMX
integration guide., and populate our own OMX llibrary..

from OpenCore - OMX Core Integration Guide,
"The OsclUuid provided is the unique API ID that identifies the OMX
core interface and cannot be modified:
(0xa054369c,0x22c5,0x412e,0x19,0x17,0x87,0x4c,0x1a,0x19,0xd4,0x5f)"

my sample .cfg file will be as below, and we get prioritized over PV
core compoenents by filename (01_myomx.cfg > pvplayer.cfg )..
(0xa054369c,0x22c5,0x412e,0x19,0x17,0x87,0x4c,0x1a,0x19,0xd4,0x5f),"lib_my_omx.so"

Hi Deva,

Yes, sorry I forgot to respond. This is solved & yes I had misread the .pdf which explicitly says that I have to use that OMX_INTERFACE_ID. I'm past this problem and tackling another one (not able to get my OMX_Init( ) function pointer).

btw, is there a way to close an issue?

Thanks for your time
HV

>not able to get my OMX_Init( ) function pointer

We populate all our pointers in a derived OMXInterface class..
you can refer our omx core plugin code at
http://git.omapzoom.org/?p=platform/hardware/ti/omx.git;a=tree;f=core_plugin

>is there a way to close an issue?

you meant OMX_Init() issue or UUID issue??

[Harish V]

Thanks for sharing the code. My interface file is similar to what you have (I just used the pv_omx_interface.cpp as the template). But, who is supposed to create an instance of the class TIOMXInterface?

 

Specifically for my case in, _OMX_MasterInit, I see that there are 2 cores (my vendor specific MPEG-4 component and the s/w version), but the function pointer to OMXInit is NULL (for core #0) while the s/w version has a valid ptr. This is where it just crashes and I don't get any thumbnails in the 'Gallery'.

 

As for the thread closing thingy, it was a general Q to make sure that people don't waste time reading issues which have already been resolved.

 

Best regards

HV

This issue is RESOLVED. There was a typo in my .cfg file, instead of
using the core_interface.so, I had put in the mp4lib_component.so & I
wasn't getting a call into PVGetInterface(). Now, it goes through and
completes the loading. I have to read up the next parts..

Cheers
HV
