Disable hardware codecs

[Uander]

Hello   ,

I have a file a audio/3gp file that I can play in eclair-2.1 emulator but its throwing error on my Zoom2
device  says "Sorry , this player doesn't support this  type of audio file " .

emulator will be using s/w codecs . while zoom2 has h/w codecs . The logic of  MMM framework is like if h/w codecs are not present it should look for s/w codec . if zoom2 is not finding h/w codec for my audio/3gp file , it should search for s/w codec and play file , why does it fails with error ?

How to disable hardware acceleration of codecs ?

Please correct me If I am wrong .




Thanks :
Uander

I don't know what Zoom2 is. But very likely, this post seems out of
place. If you are talking about builds specific for certain hardware,
then you need to go to android-porting and ask there.

you can delete ./system/etc/01_Vendor_ti_omx.cfg in your file system,
so as to use SW codecs from PVOMX components (picked up by
./system/etc/pvplayer.cfg).

Hi Uander,

You can disable Hardware acceleration by editing this file:

platform/vendor/ti/zoom2/BoardConfig.mk

But I think it's better to find the root cause of the issue, probably the first step could be to verify if the audio format is actually supported, take a look at the supported OMX roles (tComponentName):

platform/hardware/ti/omx/system/src/openmax_il/omx_core/src/OMX_core.c

Thanks,

Ricardo

Hello  ,

@Deva -

I disable h/w acceleration by removing 01_Vendor_ti_omx.cfg file . now its using s/w codecs  .  But still same error comes up . logcat says :

@Ricardo

my file is AMR-NB formatted (mimetype set as audio/3gp in mediascanner.java ), I can find
 {"OMX.TI.AMR.encode", "audio_encoder.amrnb"},
 {"OMX.TI.AMR.decode", "audio_decoder.amrnb"},

in platform/hardware/ti/omx/system/src/openmax_il/omx_core/src/OMX_core.c . so codecs support seem to listed there  .

error comes up from LCML_Init () call in  OMX_AmrDec_Utils.c . that means its unable to load codec .

Hi Uander,

Hw codecs from TIOMX_Core library is still significant, and it
shouldnt be in picture if 01_Vendor_ti_omx.cfg is deleted completely.
is it like have u renamed the file? (confirm by 'ls /etc/' after android bootup)

Intention of deleting the file is, PV OMX component sw-codecs should
be chosen via /etc/pvplayer.cfg..

Hey , it works now .

Disabled h/w codecs as suggested . It played using s/w codecs now .
